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).

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.

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.)

Make our structures equal in size with glibc structures. This should
give us plenty of space to implement any missing feature.

This patch includes just enough to keep external/chromium_org building

This is to make it possible to adopt the BSDs' implementations for a few locale
APIs in libc++ rather than writing our own, nearly identical, code.

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.

Add a function "android_dlopen_ext()", defined in <android/dlext.h>.
This is an extended version of dlopen() which takes a struct for passing
additional parameters for Android-specific functionality. This will be
used to support RELRO section sharing between separate processes.

The upstream intention was for this to be architecture-dependent, but it's a
lot clearer if we just have one copy.
