bionic_systrace.h contains an implementation of tracing that
can be used with systrace.py and its associated viewer. pthread_mutex
now uses this tracing to track pthread_mutex contention, which can be
enabled by using the "bionic" command line option to systrace.

This doesn't require us to change any of the syscall implementations
because (a) the LP32 ones have sizeof(int) == sizeof(long) anyway,
which is how we never noticed this bug before and (b) the LP64 ones
all use a 64-bit register for the result (and for the syscall number
too).

It seemed like a clever trick to use the internal log message formatting
code in syslog(3), but on reflection that means you can't (for example)
format floating point numbers. This patch switches us over to using good
old vsnprintf(3), even though that requires us to jump through a few hoops.
There's no obvious way to unit test this, so I wrote a little program and
ran that.

This also brings our copy of strftime.c much closer to upstream, though
we still have several GNU extensions and hacks to deal with Android32's
broken time_t.

I've also added insque(3) and remque(3) (from NetBSD because the OpenBSD
ones are currently broken for non-circular lists).
I've not added the three hash table functions that should be in this header
because they operate on a single global hash table and thus aren't likely
to be useful.

Save and restore floating point registers via 64-bit
load/stores when possible. Use assembler's builtin macro
ops to generate pairs of 32-bit load/stores on Mips I cpus.
Some cpus or FR modes have only 16 even-numbered dp fp regs.
This is exposed by _MIPS_FPSET, defined by existing compilers.

The change that added this support causes a cpu hard lock on one
device. This code clearly isn't at fault, but disabling it to
unblock until we can find a real fix.

Explicitly tell 32-bit links that they are doing 32-bit links.
This is needed when using united 32-bit and 64-bit toolchains.
This is harmless when using older separate 32-only toolchains.

The getentropy_linux.c is lightly modified to build on Android, but we're now
completely in sync with upstream OpenBSD's arc4random implementation.

Since we don't have syslogd on Android and you can't run one on a non-rooted
device, it's more useful if syslog output just goes to the regular Android
logging system.

Some platform code is apparently compiled with switches that do
not support char16_t and char32_t. This caused stdatomic.h to fail
to compile. This CL makes stdatomic.h usable in those environments.

To avoid any issues calling malloc related routines, use mmap/munmap.
Specifically, this avoids any problems when this is compiled into a
malloc debug shared library.

Had intended to remove this one before submitting the locale changes,
but forgot. It isn't a standard ctype function, so we don't need it.

There were two bugs here:
- For 64 bit values, this did not properly round up.
- The macro rounded to the power of 2 less than value, not to the power
of 2 greater than value.
