fff3c0fdcf Align arm64 stacks to 16 bytes in __bionic_clone.
Also ensure that arm64/x86-64/x86 assembler uses local labels.
(There are are so many non-local labels in arm that fixing them
seems out of scope.)

Also synchronize the __bionic_clone.S comments.

Included is a new target generic-neon that will use neon instructions
on 64 bit platforms where appropriate.

954cf0d4e2 Hide the __bionic_clone and __bionic_clone_entry implementation details.
clone(2) is the public symbol.

Also switch a test from __bionic_clone to clone; testing public API
means the test now works on glibc too.

Elliott Hughes
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.)

c78368f04f Change the interface for fatal logging.
This more general interface lets liblog give us any fatal log message,
regardless of source. This means we can remove the special case for
LOG_ALWAYS_FATAL with a simpler scheme that automatically works for
the VM too.

0686d5e26f Reserve some space in sem_t for the future.
Reserve 12 more bytes in sem_t to give room for future implementation
improvements. This gets us to a 16 bytes sem_t. Glibc uses 32 bytes (16
actual use + 16 reserved), while OpenBSD has 16 bytes (out of which 4
are for padding).

7d8f303353 Allow for better utmp logging.
Increase (UT_NAMESIZE,UT_LINESIZE,UT_HOSTSIZE) to (32,32,256).

Nobody writes utmp on Android but it would be nice to be aligned
with others who use 32,32,256 (like glibc). If ever used it will produce
nicer logging. There is no consensus in BSDs for these values.

7c435f2415 Leave more space for extensions in pthread_rwlockattr_t
Change pthread_rwlockattr_t from int to long. On LP64 this gives us more
room for extensibility since longs are 8 bytes. glibc also reserves 8
bytes for this.

2605261691 Test that relro sharing actually saves memory.
Spawn 20 child processes, have them all load the library, and compare
the total PSS used in the case where we use dlopen() and the case where
we use android_dlopen_ext() with relro sharing. We assume we will save
at least 10% of the memory; in practise this example saves 40% or more
so this should be a reasonable threshold.

9a5a3e8e74 Fix <math.h> to quieten most of our warnings.
I've reported the wcsftime bug upstream, but we really just want to use -D
to ensure the buggy code isn't built. (I've also brought our strftime a bit
closer to upstream now we have the right define.)

I don't think upstream is likely to fix all their sign-compare and
uninitialized warnings, so let's just silence them.

As for libm, again upstream isn't likely to fix all their warnings, and
silencing those made the ones that were our fault stand out. I've fixed
our <math.h> to fix the warnings caused by our lack of definitions for
the non-imprecise long-double functions. I checked the C99 standard, and
all these functions are there.

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.
