- 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.

typeof() is a gcc builtin and is not always available (such as clang when
-std=c*). Both gcc and clang always expose __typeof__(), so just use that.

- used underscore_style_for_vars
- extracted time related functionality into a function
- cleaned up style
- removed unused fields from pthread_rwlock_t on LP64
- changed reservation in pthread_rwlock_t so that the size of the
structure equals glibc version

Also hide part of the system properties compatibility code, since
we needed to touch that to keep it building.
I'll remove __futex_syscall4 and futex in a later patch.

There's no need to expose gregset_t and fpregset_t when they
are not used in ucontext_t.

Use the upstream OpenBSD implementations of these functions.
Also ensure we have symbols for htonl, htons, ntohl, and ntohs.
gtest doesn't like us using the macro versions in ASSERT_EQ.

This increases bionic source compatibility with other libcs where
"wctype_t foo = 0;" is valid without -fpermissive.

The kernel struct has some spare space at the end too, and some extra
fields, so having a bit of flexibility in statvfs might be worthwhile.

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.)

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).

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.

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.

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.

__SIGRTMIN will continue to tell the truth. This matches glibc's
behavior (as evidenced by the fact that we don't need a special case
in the strsignal test now).
