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.

f6d2ca2696 Expose __srefill for LP64 until we can fix the NDK.
The LP64 has a duplicate copy of part of stdio, and relies
on bionic supplying this part. We should remove the hack from
the NDK, at least for LP64, and then revert this.

The unwinder will end up on the parent thread's stack if the return
address register is not cleared.

Dan Albert
a7821b7121 Use __typeof__() instead of typeof()
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.

The NDK apparently includes an android_support.a library that
refers to __srefill in its copy of the vsnprintf implementation.

Anthony King <anthonydking@slimroms.net> reports that for Grouper the
Nvidia GL blobs need access to __swbuf. This is because the old <stdio.h>
had inline getc and putc implementations that directly referred to these
symbols.

This reverts commit 8167dd7cb9.

For some reason I thought the bcopy change was bzero. The bcopy code doesn't pass our tests, so reverting until I can figure out what's wrong.

8df0fe0c74 Clear link register in __bionic_clone.
Since __bionic_clone uses tail-call to invoke __bionic_clone_entry,
at runtime the unwinder will reach the stack of the clone() function,
which belongs to the parent thread, if the link register is not cleared.

2899de9b05 Hide various stdio implementation details.
I've left __sF exposed since that's how the OpenBSD stdin, stdout, stderr
are implemented. Other BSDs and glibc use a separate global for each instead
of an array.

3c005d6019 Do not add arcs to the soinfo graph on dlopen
While introducing RTLD_NOLOAD in b648a8a5 a change in how soinfo structs are
connected was also introduced. When calling dlopen the library that is loaded
is added as a child to the soinfo from which the caller comes - i.e. building a
dependency graph.

Unfortunately this shows issues upon unloading, such as blowing the stack if
there are loops in the graph.

This change reverts that part of b648a8a5, keeping everything as a child of the
root soinfo.

92687e41bc Cleaned up pthread rwlocks implementation.
- 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

6e599a904b Remove the tkill(2) stub.
glibc doesn't have tkill or tgkill and says "use syscall(3) instead".
I've left tgkill since it's quite widely used, but there's no reason
to have tkill as well.
