Most of these tests were in system/extras, but I've added more to cover other
cases explicitly mentioned by POSIX.

pthread_no_op_detach_after_join test from bionic-unit-tests hangs
on x86 emulator. There is a race in the pthread_join, pthread_exit,
pthread_detach functions:
- pthread_join waits for the non-detached thread
- pthread_detach sets the detached flag on that thread
- the thread executes pthread_exit which just kills the now-detached
thread, without sending the join notification.
This patch improves the test so it fails on ARM too, and modifies
pthread_detach to behave more like glibc, not setting the detach state if
called on a thread that's already being joined (but not returning an error).

The first NULL pointer check against `attr' suggests that `attr' can
be NULL. Then later `attr' is directly dereferenced, suggesting the
opposite.
if (attr == NULL) {
...
} else {
...
}
...
if (attr->stack_base == ...) { ... }
The public API pthread_create(3) allows NULL, and interprets it as "default".
Our implementation actually swaps in a pointer to the global default
pthread_attr_t, so we don't need any NULL checks in _init_thread. (The other
internal caller passes its own pthread_attr_t.)

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.

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.

Also separate out the C++ files so we can use -Werror on them. I'd
rather wait for LOCAL_CPPFLAGS to be in AOSP, but this also lets us
see which files still need to be sorted into one bucket or the other.

I'll come back and remove the separate files (and change the regular 'generate'
script) when the separate files are obsolete, but in the interim period, it's
easier to have both old and new files available.

This patch updates the C library headers to provide ucontext_t
definitions for three architectures.
+ Fix <signal.h> to always define 'struct sigcontext'.
The new declarations are announced with new macros defined in
<sys/cdefs.h> in order to make it easier to adapt client code
that already defines its own, incompatible, versions of the
structures seen here.

I gave up trying to use the usual thread-local buffer idiom; calls to
calloc(3) and free(3) from any of the "dl" functions -- which live in
the dynamic linker -- end up resolving to the dynamic linker's stubs.
I tried to work around that, but was just making things more complicated.
This alternative costs us a well-known TLS slot (instead of the
dynamically-allocated TLS slot we'd have used otherwise, so no difference
there), plus an extra buffer inside every pthread_internal_t.

LONG_LONG_MIN, LONG_LONG_MAX and ULONG_LONG_MAX are
GLibc-specific macros that are better defined in <limits.h>
instead of the current exotic location (<pthread.h>).
Note that GCC's <limits.h> only defines these macros
when __GNU_LIBRARY__ is also defined. This is only the
case when building against GLibc, so manually redefine
the macros here.
Note that using LLONG_MIN/LLONG_MAX/ULLONG_MAX is the
C99-compliant way to get these values, but it's easier
to define these compatibility macros for the sake of
porting existing code.

perf_event_open syscall has a different syscall number for
the 3 supported architectures: arm, x86 and mips. Currenlty
only the arm syscall number is defined for all architectures.
Tracing tools like perf will not work on other architectures
than arm.
Add the different values for perf_event_open on x86 and mips
and run gensyscalls.py to update generated headers.
