4f251bee5d Don't corrupt the thread list if the main thread exits.
...and don't pass a non-heap pointer to free(3), either.

This patch replaces the "node** prev" with the clearer "node* prev"
style and fixes the null pointer dereference in the old code. That's
not sufficient to fix the reporter's bug, though. The pthread_internal_t*
for the main thread isn't heap-allocated --- __libc_init_tls causes a
pointer to a statically-allocated pthread_internal_t to be added to
the thread list.

1a6961650c Stop defining our own PAGE_SIZE and PAGE_MASK, and test dlclose(3) too.
Also remove an unnecessary #include and a now-obsolete TODO.

124fae9eab Reject .so files with no sysv hash table.
Also ensure that dlopen(3) errors always include the name of the library we
failed to open.

Also fix a bug where we'd fall back to searching LD_LIBRARY_PATH and the
built-in paths for names that include slashes.

58b575485c Clean up the <libgen.h> implementation a little, bring in tests.
Most of these tests were in system/extras, but I've added more to cover other
cases explicitly mentioned by POSIX.

10ce96944e Fix bug in pthread_join, pthread_exit, pthread_detach
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).

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.

5419b94747 Make dlerror(3) thread-safe.
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.

3b297c4079 Fix dlerror(3).
Add unit tests for dlerror(3) in various situations. I think We're at least
as good as glibc now.

Also factor out the ScopedPthreadMutexLock and use it here too.
