Release libbsd 0.12.2

With linker sections GC enabled, we get a test failure in `nlist.c`:
```
nlist: nlist.c:72: main: Assertion `rc == 0' failed.
```

This turns out to be because several sections used by the test can be discarded:
```
ld: removing unused section '.text.func_pub' in file 'nlist.o'
ld: removing unused section '.bss.data_pub_uninit' in file 'nlist.o'
ld: removing unused section '.data.data_pub_init' in file 'nlist.o'
```

Reproduced with `CFLAGS="-Og -fdata-sections -ffunction-sections"` and
`LDFLAGS="-Wl,-O1 -Wl,--as-needed -Wl,--gc-sections -Wl,-z,start-stop-gc"`.

Additionally, `LDFLAGS="... -Wl,--print-gc-sections"` can help with diagnosing
which sections get removed.

We already mark these symbols as `used`, but we need `retain` [0] for them
to survive linker GC too.

+for include usage.)
+.Ft void
+.Fn TIMEVAL_TO_TIMESPEC "struct timeval *tv" "struct timespec *ts"
+.Ft void
+.Fn TIMESPEC_TO_TIMEVAL "struct timeval *tv" "struct timespec *ts"
+.Sh DESCRIPTION
+The
+.Va timeval
+structure represents elapsed time, in whole seconds,
+and the rest of the elapsed time in microseconds.
+.Pp
+The
+.Va timespec
+structure represents elapsed time, in whole seconds,
+and the rest of the elapsed time in nanoseconds.
+.Pp
+A microsecond is equal to one millionth of a second,
+1000 nanoseconds, or 1/1000 milliseconds.
+To ease the conversions, the macros
+.Fn TIMEVAL_TO_TIMESPEC
+and
+.Fn TIMESPEC_TO_TIMEVAL
+can be used to convert between
+.Em struct timeval
+and
+.Em struct timespec .
+.Sh EXAMPLES
+It can be stressed that the traditional
+.Tn UNIX
+.Va timeval
+and
+.Va timespec
+structures represent elapsed time, measured by the system clock.
+The following sketch implements a function suitable
+for use in a context where the
+.Va timespec
+structure is required for a conditional timeout:
+.Bd -literal -offset indent
+static void
+example(struct timespec *spec, time_t minutes)
+{
+	struct timeval elapsed;
+
+	(void)gettimeofday(&elapsed, NULL);
+
+	TIMEVAL_TO_TIMESPEC(&elapsed, spec);
+
+	/* Add the offset for timeout in minutes. */
+	spec->tv_sec = spec->tv_sec + minutes * 60;
+}
+.Ed
+.Pp
+A better alternative would use the more precise
+.Xr clock_gettime 2 .

 .Sh DESCRIPTION
-This family of functions provides higher quality data than those
-described in
-.Xr rand 3 ,
+The
+.Nm
+family of functions provides a cryptographic pseudorandom number
+generator automatically seeded from the system entropy pool and safe to
+use from multiple threads.
+.Nm
+is designed to prevent an adversary from guessing outputs,
+unlike
+.Xr rand 3
+and
 .Xr random 3 ,
-and
-.Xr rand48 3 .
+and is faster and more convenient than reading from
+.Pa /dev/urandom
+directly.
 .Pp
-Use of these functions is encouraged for almost all random number
-consumption because the other interfaces are deficient in either
-quality, portability, standardization, or availability.
-These functions can be called in almost all coding environments,
-including
-.Xr pthreads 3
-and
-.Xr chroot 2 .
-.Pp
-High quality 32-bit pseudo-random numbers are generated very quickly.
-On each call, a cryptographic pseudo-random number generator is used
-to generate a new result.
-One data pool is used for all consumers in a process, so that consumption
-under program flow can act as additional stirring.
-The subsystem is re-seeded from the kernel random number subsystem using
-.Xr getentropy 2
-on a regular basis, and also upon
-.Xr fork 2 .
-.Pp
-The
 .Fn arc4random
-function returns a single 32-bit value.
-.Pp
-The
-.Fn arc4random_buf
-function fills the region
-.Fa buf
-of length
-.Fa nbytes
-with random data.
+returns an integer in [0, 2^32) chosen independently with uniform
+distribution.
 .Pp
 .Fn arc4random_uniform
-will return a single 32-bit value, uniformly distributed but less than
-.Fa upper_bound .
-This is recommended over constructions like
-.Dq Li arc4random() % upper_bound
-as it avoids "modulo bias" when the upper bound is not a power of two.
-In the worst case, this function may consume multiple iterations
-to ensure uniformity; see the source code to understand the problem
-and solution.
+returns an integer in [0,
+.Fa bound )
+chosen independently with uniform distribution.
 .Pp
+.Fn arc4random_buf
+stores
+.Fa len
+bytes into the memory pointed to by
+.Fa buf ,
+each byte chosen independently from [0, 256) with uniform
+distribution.
+.Pp
+.Fn arc4random_stir
+draws entropy from the operating system and incorporates it into the
+library's PRNG state to influence future outputs.
+.Pp
+.Fn arc4random_addrandom
+incorporates
+.Fa len
+bytes, which must be nonnegative, from the buffer
+.Fa buf ,
+into the library's PRNG state to influence future outputs.
+.Pp
+It is not necessary for an application to call
+.Fn arc4random_stir
+or
+.Fn arc4random_addrandom
+before calling other
+.Nm
+functions.
+The first call to any
+.Nm
+function will initialize the PRNG state unpredictably from the system
+entropy pool.
+.Sh SECURITY MODEL
 The
-.Fn arc4random_stir
-function reads data from
-.Xr getentropy 2
-and uses it to re-seed the subsystem via
-.Fn arc4random_addrandom .
+.Nm
+functions provide the following security properties against three
+different classes of attackers, assuming enough entropy is provided by
+the operating system:
+.Bl -enum -offset abcd
+.It
+An attacker who has seen some outputs of any of the
+.Nm
+functions cannot predict past or future unseen outputs.
+.It
+An attacker who has seen the library's PRNG state in memory cannot
+predict past outputs.
+.It
+An attacker who has seen one process's PRNG state cannot predict past
+or future outputs in other processes, particularly its parent or
+siblings.
+.El
+.Pp
+One
+.Sq output
+means the result of any single request to an
+.Nm
+function, no matter how short it is.
+.Pp
+The second property is sometimes called
+.Sq forward secrecy ,
+.Sq backtracking resistance ,
+or
+.Sq key erasure after each output .
+.Sh IMPLEMENTATION NOTES
+The
+.Nm
+functions are currently implemented using the ChaCha20 pseudorandom
+function family.
+For any 32-byte string
+.Fa s ,
+.Pf ChaCha20_ Fa s
+is a function from 16-byte strings to 64-byte strings.
+It is conjectured that if
+.Fa s
+is chosen with uniform distribution, then the distribution on
+.Pf ChaCha20_ Fa s
+is indistinguishable to a computationally bounded adversary from a
+uniform distribution on all functions from 16-byte strings to 64-byte
+strings.
+.Pp
+The PRNG state is a 32-byte ChaCha20 key
+.Fa s .
+Each request to
+an
+.Nm
+function
+.Bl -bullet -offset abcd -compact
+.It
+computes the 64-byte quantity
+.Fa x
+=
+.Pf ChaCha20_ Fa s Ns Pq 0 ,
+.It
+splits
+.Fa x
+into two 32-byte quantities
+.Fa s'
+and
+.Fa k ,
+.It
+replaces
+.Fa s
+by
+.Fa s' ,
+and
+.It
+uses
+.Fa k
+as output.
+.El
 .Pp
-There is no need to call
-.Fn arc4random_stir
-before using
 .Fn arc4random
-functions family, since
-they automatically initialize themselves.
-.Sh RETURN VALUES
-These functions are always successful, and no return value is
-reserved to indicate an error.
+yields the first four bytes of
+.Fa k
+as output directly.
+.Fn arc4random_buf
+either yields up to 32 bytes of
+.Fa k
+as output directly, or, for longer
+requests, uses
+.Fa k
+as a ChaCha20 key and yields the concatenation
+.Pf ChaCha20_ Fa k Ns Pq 0
+||
+.Pf ChaCha20_ Fa k Ns Pq 1
+|| ... as output.
+.Fn arc4random_uniform
+repeats
+.Fn arc4random
+until it obtains an integer in [2^32 %
+.Fa bound ,
+2^32), and reduces that modulo
+.Fa bound .
+.Pp
+The PRNG state is per-thread, unless memory allocation fails inside the
+library, in which case some threads may share global PRNG state with a
+mutex.
+The global PRNG state is zeroed on fork in the parent via
+.Xr pthread_atfork 3 ,
+and the per-thread PRNG state is zeroed on fork in the child via
+.Xr minherit 2
+with
+.Dv MAP_INHERIT_ZERO ,
+so that the child cannot reuse or see the parent's PRNG state.
+The PRNG state is reseeded automatically from the system entropy pool
+on the first use of an
+.Nm
+function after zeroing.
+.Pp
+The first use of an
+.Nm
+function may abort the process in the highly unlikely event that
+library initialization necessary to implement the security model fails.
+Additionally,
+.Fn arc4random_stir
+and
+.Fn arc4random_addrandom
+may abort the process in the highly unlikely event that the operating
+system fails to provide entropy.

-The original version of this random number generator used the

-A good mnemonic is

+The name
+.Sq arc4random
+was chosen for hysterical raisins -- it was originally implemented
+using the RC4 stream cipher, which has been known since shortly after
+it was published in 1994 to have observable biases in the output, and
+is now known to be broken badly enough to admit practical attacks in

+Unfortunately, the library found widespread adoption and the name stuck
+before anyone recognized that it was silly.
+.Pp
+The signature of
+.Fn arc4random_addrandom
+is silly.
+There is no reason to require casts or accept negative lengths:
+it should take a
+.Vt void *
+buffer and a
+.Vt size_t
+length.
+But it's too late to change that now.
+.Pp
+.Fn arc4random_uniform
+does not help to choose integers in [0,
+.Fa n )
+uniformly at random when
+.Fa n
+> 2^32.
+.Pp
+The security model of
+.Nm
+is stronger than many applications need, and stronger than other
+operating systems provide.
+For example, applications encrypting messages with random, but not
+secret, initialization vectors need only prevent an adversary from
+guessing future outputs, since past outputs will have been published
+already.
+.Pp
+On the one hand,
+.Nm
+could be marginally faster if it were not necessary to prevent an
+adversary who sees the state from predicting past outputs.
+On the other hand, there are applications in the wild that use
+.Nm
+to generate key material, such as OpenSSH, so for the sake of
+.Nx
+users it would be imprudent to weaken the security model.
+On the third hand, relying on the security model of
+.Nm
+in
+.Nx
+may lead you to an unpleasant surprise on another operating system
+whose implementation of
+.Nm
+has a weaker security model.
+.Pp
+One may be tempted to create new APIs to accommodate different
+security models and performance constraints without unpleasant
+surprises on different operating systems.
+This should not be done lightly, though, because there are already too
+many different choices, and too many opportunities for programmers to
+reach for one and pick the wrong one.

-.Pp
-The
-.Va tv_sec
-member is again the elapsed time in whole seconds.
-The
-.Va tv_nsec
-member represents the rest of the elapsed time in nanoseconds.
-.Pp
-A microsecond is equal to one millionth of a second,
-1000 nanoseconds, or 1/1000 milliseconds.
-To ease the conversions, the macros
-.Fn TIMEVAL_TO_TIMESPEC
-and
-.Fn TIMESPEC_TO_TIMEVAL
-can be used to convert between
-.Em struct timeval
-and
-.Em struct timespec .
-.El
-.Sh EXAMPLES
-It can be stressed that the traditional
-.Tn UNIX
-.Va timeval
-and
-.Va timespec
-structures represent elapsed time, measured by the system clock.
-The following sketch implements a function suitable
-for use in a context where the
-.Va timespec
-structure is required for a conditional timeout:
-.Bd -literal -offset indent
-static void
-example(struct timespec *spec, time_t minutes)
-{
-	struct timeval elapsed;
-
-	(void)gettimeofday(&elapsed, NULL);
-
-	_DIAGASSERT(spec != NULL);
-	TIMEVAL_TO_TIMESPEC(&elapsed, spec);
-
-	/* Add the offset for timeout in minutes. */
-	spec->tv_sec = spec->tv_sec + minutes * 60;
