cd32219c5b Remove declarations related to cuserid(3).
cuserid(3) was removed from POSIX 2004, and we don't have an
implementation anyway.

a382a792a4 Hide non-standard syslog API.
The definitions are still available on LP32 for binary compatibility, but
they're gone on LP64, and the declarations are gone everywhere.

We should probably just make syslog(3) log to the regular Android log,
but that's a job for another day.

47ba295b06 Rewrite and hide longjmperror.
This shouldn't be public API, isn't supported on x86/x86_64, and it's
unlikely anyone would have actually seen the message before anyway.
Using __libc_fatal makes it much more likely to be seen.

Elliott Hughes
69f05d291d Fix the printf family for non-ASCII.
The bug here turned out to be that we hadn't increased the constant
corresponding to the maximum number of bytes in a character to match
our new implementation, so any character requiring more than a byte
in UTF-8 would break our printf family.

40fca0f08b Removes index() from bionic.
This function has been removed from POSIX.

Unfortunately, we can't leave #define index(a, b) strchr((a), (b)) in its place
because defining a preprocessor macro for index() breaks a whole lot of code.

bdca3802c9 Remove unnecessary padding in ucontext_t
- removed extra padding from ucontex_t on x86, x86_64 and mips
- force ucontext_t struct to use 64 bits for the sigmask on all arches
(previsouly wrong since sigset_t on arm and x86 is only 32 bits)
- arm and arm64 continue to use padding to match glibc sigset_t

This brings Bionic on par with the kernel w.r.t ucontext padding.

4aa2e6a32a Give bionic's __ANDROID_API__ a more reasonable value.
This matches what frameworks/base does with Build.VERSION and means that
bionic's version number will always sort >= than any released version.
This should prevent confusion in code that builds both against bionic
and the NDK.

(Note that <sys/cdefs.h> drags this in, so it's always in the namespace.)

are for padding).

nicer logging. There is no consensus in BSDs for these values.

9ded07cff6 bionic: make epoll_event structure packed
Description: In the kernel the epoll_event structure is packed
in 64 bit kernel builds to allow the structure to be more easily
compatible with 32 bit user space.  As a result, when user space
is 64-bit the structure must be packed as well.

Add unit test to show the ptr alignment issue.

01ae00f317 Switch to the OpenBSD implementations of the wide scanf functions.
This also gets us the C99 wcstoimax and wcstoumax, and a working fgetwc and
ungetwc, all of which are needed in the implementation.

This also brings several other files closer to upstream.

3d7a0d9b08 Switch to the OpenBSD wcsto* functions.
This replaces a partial set of non-functional functions with a complete
set of functions, all of which actually work.

This requires us to implement mbsnrtowcs and wcsnrtombs which completes
the set of what we need for libc++.

The mbsnrtowcs is basically a copy & paste of wcsnrtombs, but I'm going
to go straight to looking at using the OpenBSD UTF-8 implementation rather
than keep polishing our home-grown turd.

(This patch also opportunistically switches us over to upstream btowc,
mbrlen, and wctob, since they're all trivially expressed in terms of
other functions.)

Add flags and a file descriptor to android_dlopen_ext() to allow writing
the RELRO section of the loaded library to a file after relocation
processing, and to allow mapping identical pages from the file over the
top of relocated memory in another process. Explicitly comparing the
pages is required in case a page contains a reference to a symbol
defined in another library loaded at a random base address.

Add flags and parameters to android_dlopen_ext() to allow loading a
library at an already-reserved fixed address. If the library to be
loaded will not fit within the space reserved, then the linker will
either fail, or allocate its own address space as usual, according to
which flag has been specified. This behaviour only applies to the
specific library requested; any other libraries loaded as dependencies
will be loaded in the normal fashion.

There is a new gtest included to cover the functionality added.

a0cd9bc339 Add si_timerid to <signal.h>.
The kernel uses the very misleading name "si_tid", but glibc uses the more
intention-revealing "si_timerid". We should let people use that.

(Added because I wanted to improve SI_TIMER siginfo_t dumping in strace.)

Our sigset_t definition hasn't been tied to our NSIG definition since we
switched to uapi headers, so we can now fix it without breaking the LP32 ABI.
The kernel uapi headers define and use _NSIG, so we need to have our scripts
rename the kernel's definitions out of the way, then we can define _NSIG
and NSIG in terms of the kernel's off-by-one value.

323d4b6f68 Add "__noreturn" to assert and assert2
These functions should print assertion violation messages and then
call abort(). They do really not return control flow afterwards.
Consider the declaration of the similar __assert_fail from glibc:

extern void __assert_fail (const char *__assertion,
                           const char *__file,
			   unsigned int __line,
                           const char *__function)
     __THROW __attribute__ ((__noreturn__));

Bionic has __noreturn defined in sys/cdefs.h to be that GNU
noreturn attribute.

This patch has a practical value. Consider the following function:

void check(void* ptr) {
  assert(ptr != NULL);
}

Without this patch applied, gcc (and presumably clang) shows even in
debug mode:

warning: unused parameter 'ptr' [-Wunused-parameter]

In release mode, NDEBUG is defined and assert() becomes a no-op, as
one should expect. Thus, the warning is shown correctly then.

Another code sample:

float array[2];
int i = 3;
...
assert(i < 2);
array[i] = 0;

gcc says,

warning: array subscript is below array bounds [-Warray-bounds]

In other words, without noreturn attribute, assertions do not
allow a compiler's static analyzer to properly understand
the preconditions.

0f461e35f6 Fix <sys/resource.h>.
The situation here is a bit confusing. On 64-bit, rlimit and rlimit64 are
the same, and so getrlimit/getrlimit64, setrlimit/setrlimit64,
and prlimit/prlimit64 are all the same. On 32-bit, rlimit and rlimit64 are
different. 32-bit architectures other than MIPS go one step further by having
an even more limited getrlimit system call, so arm and x86 need to use
ugetrlimit instead of getrlimit. Worse, the 32-bit architectures don't have
64-bit getrlimit- and setrlimit-equivalent system calls, and you have to use
prlimit64 instead. There's no 32-bit prlimit system call, so there's no
easy implementation of that --- what should we do if the result of prlimit64
won't fit in a struct rlimit? Since 32-bit survived without prlimit/prlimit64
for this long, I'm not going to bother implementing prlimit for 32-bit.

We need the rlimit64 functions to be able to build strace 4.8 out of the box.
