(Doesn't try to increase the number of TLS slots; that leads to
an inability to boot. Adds more tests.)

2a1bb4e646 More pthreads cleanup.
POSIX says pthread_create returns EAGAIN, not ENOMEM.

Also pull pthread_attr_t functions into their own file.

Also pull pthread_setname_np into its own file.

Also remove unnecessary #includes from pthread_key.cpp.

Also account for those pthread keys used internally by bionic,
so they don't count against the number of keys available to user
code. (They do with glibc, but glibc's limit is the much more
generous 1024.)

Also factor out the common errno-restoring idiom to reduce gotos.

ad59322ae4 Pull the pthread_key_t functions out of pthread.c.
This was originally motivated by noticing that we were setting the
wrong bits for the well-known tls entries. That was a harmless bug
because none of the well-known tls entries has a destructor, but
it's best not to leave land mines lying around.

Also add some missing POSIX constants, a new test, and fix
pthread_key_create's return value when we hit the limit.

There's now only one place where we deal with this stuff, it only needs to
be parsed once by the dynamic linker (rather than by each recipient), and it's
now easier for us to get hold of auxv data early on.

1e980b6bc8 Fix the duplication in the debugging code.
We had two copies of the backtrace code, and two copies of the
libcorkscrew /proc/pid/maps code. This patch gets us down to one.

We also had hacks so we could log in the malloc debugging code.
This patch pulls the non-allocating "printf" code out of the
dynamic linker so everyone can share.

This patch also makes the leak diagnostics easier to read, and
makes it possible to paste them directly into the 'stack' tool (by
using relative PCs).

This patch also fixes the stdio standard stream leak that was
causing a leak warning every time tf_daemon ran.

2c5153b043 libc: add getauxval()
Add support for getauxval().  This method allows a program an easy way
to retrieve information from the kernel auxiliary vector, and will
hopefully replace other clumsy ways of accessing this same information.

This particular function was also added to glibc in glibc 2.16.
See the following URLs for more details.

a4b2dc016f Add signalfd call to bionic
Add signalfd() call to bionic.

Adding the signalfd call was done in 3 steps:
- add signalfd4 system call (function name and syscall
  number) to libc/SYSCALLS.TXT
- generate all necessary headers by calling
  libc/tools/gensyscalls.py. This patch is adding
  the generated files since the build system
  does not call gensyscalls.py.
- create the signalfd wrapper in signalfd.cpp and add
  the function prototype to sys/signalfd.h

(cherry-pick of 0c11611c11, modified to
work with older versions of GCC still in use on some branches.)

20c4a3a8ee Replace .S version of x86 crtfiles with .c version
This patch replaces .S versions of x86 crtfiles with .c which are much
easier to support. Some of the files are matching .c version of Arm
crtfiles. x86 files required some cleanup anyway and this cleanup actually
led to matching Arm files.

I didn't change anything to share the same crt*.c between x86 and Arm. I
prefer to keep them separate for a while in case any change is required
for one of the arch, but it's good thing to do in the following patches.

c30396f5f2 libc: Fix alphasort() signature (and implementation).
The declaration for alphasort() in <dirent.h> used the deprecated:

  int alphasort(const void*, const void*);

while both Posix and GLibc use instead:

  int alphasort(const struct dirent** a, const struct dirent** b);

See: http://pubs.opengroup.org/onlinepubs/9699919799/functions/alphasort.html

This patch does the following:

- Update the declaration to match Posix/GLibc
- Get rid of the upstream BSD code which isn't compatible with the new
  signature.
- Implement a new trivial alphasort() with the right signature, and
  ensure that it uses strcoll() instead of strcmp().
- Remove Bionic-specific #ifdef .. #else .. #endif block in
  dirent_test.cpp which uses alphasort().

Even through strcoll() currently uses strcmp(), this does the right
thing in the case where we decide to update strcoll() to properly
implement locale-specific ordered comparison.

ad88a08631 Per-thread -fstack-protector guards for x86.
Based on a pair of patches from Intel:

  https://android-review.googlesource.com/#/c/43909/
  https://android-review.googlesource.com/#/c/44903/

For x86, this patch supports _both_ the global that ARM/MIPS use
and the per-thread TLS entry (%gs:20) that GCC uses by default. This
lets us support binaries built with any x86 toolchain (right now,
the NDK is emitting x86 code that uses the global).

I've also extended the original tests to cover ARM/MIPS too, and
be a little more thorough for x86.
