Fix pthread_attr_getstack__main_thread.
There were two problems here:
* This would fail when run with unlimited stack, because it didn't know
that bionic reports unlimited stacks as 8MiB.
* This would leave RLIMIT_STACK small, causing failures to exec (so the
popen and system tests would fail).
(cherry-pick of 27a9aed81978af792cb06035a1619c8141a5fb5b plus the
new ScopeGuard.h from a3ad450a2e3fb6b3fe359683b247eba20896f646.)

Have pthread_attr_getstack for the main thread report RLIMIT_STACK...
...rather than just what's already mapped in. This seems somewhat
contrary to POSIX's "All pages within the stack described by stackaddr
and stacksize shall be both readable and writable by the thread", but
it's what glibc does.

Fix pthread_getattr_np for the main thread.
On most architectures the kernel subtracts a random offset to the stack
pointer in create_elf_tables by calling arch_align_stack before writing
the auxval table and so on. On all but x86 this doesn't cause a problem
because the random offset is less than a page, but on x86 it's up to two
pages. This means that our old technique of rounding the stack pointer
doesn't work. (Our old implementation of that technique was wrong too.)
It's also incorrect to assume that the main thread's stack base and size
are constant. Likewise to assume that the main thread has a guard page.
The main thread is not like other threads.
This patch switches to reading /proc/self/maps (and checking RLIMIT_STACK)
whenever we're asked.

Do a second key cleanup in pthread_exit.
During pthread_exit, the keys are cleaned. Unfortunately, a call to
free occurs after the cleanup and the memory for some of the keys
is recreated when using jemalloc. The solution is to do the key
cleanup twice.
Also, modify the pthread_detach__leak test to be less flaky
when run on a jemalloc system.

Fix pthread_join.
Let the kernel keep pthread_internal_t::tid updated, including
across forks and for the main thread. This then lets us fix
pthread_join to only return after the thread has really exited.
Also fix the thread attributes of the main thread so we don't
unmap the main thread's stack (which is really owned by the
dynamic linker and contains things like environment variables),
which fixes crashes when joining with an exited main thread
and also fixes problems reported publicly with accessing environment
variables after the main thread exits (for which I've added a new
unit test).
In passing I also fixed a bug where if the clone(2) inside
pthread_create(3) fails, we'd unmap the child's stack and TLS (which
contains the mutex) and then try to unlock the mutex. Boom! It wasn't
until after I'd uploaded the fix for this that I came across a new
public bug reporting this exact failure.

<pthread.h> fixes and pthread cleanup.
<pthread.h> was missing nonnull attributes, noreturn on pthread_exit,
and had incorrect cv qualifiers for several standard functions.
I've also marked the non-standard stuff (where I count glibc rather
than POSIX as "standard") so we can revisit this cruft for LP64 and
try to ensure we're compatible with glibc.
I've also broken out the pthread_cond* functions into a new file.
I've made the remaining pthread files (plus ptrace) part of the bionic code
and fixed all the warnings.
I've added a few more smoke tests for chunks of untested pthread functionality.
We no longer need the libc_static_common_src_files hack for any of the
pthread implementation because we long since stripped out the rest of
the armv5 support, and this hack was just to ensure that __get_tls in libc.a
went via the kernel if necessary.
This patch also finishes the job of breaking up the pthread.c monolith, and
adds a handful of new tests.

pthread_attr_setguardsize and pthread_attr_setstacksize were reporting EINVAL

unnecessary. We can just round like POSIX suggests and glibc already does.

Handles spurious wake-ups in pthread_join()
Removed 'join_count' from pthread_internal_t and switched to using the flag
PTHREAD_ATTR_FLAG_JOINED to indicate if a thread is being joined. Combined with
a switch to a while loop in pthread_join, this fixes spurious wake-ups but
prevents a thread from being joined multiple times. This is fine for
two reasons:
1) The pthread_join specification allows for undefined behavior when multiple
threads try to join a single thread.
2) There is no thread safe way to allow multiple threads to join a single
thread with the pthread interface. The second thread calling pthread_join
could be pre-empted until the thread is destroyed and its handle reused for
a different thread. Therefore multi-join is always an error.

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.

Only have one copy of the kernel_sigset_t hack, and add more tests.

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.

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).

Fix the pthread_join on self error case.
We should return EDEADLK, not deadlock the calling thread.

Add more pthreads tests.
Someone reported a bug if pthread_detach is called while a pthread_join is
already in progress, but I'm unable to reproduce it. Keep the tests I wrote,
though.

Don't corrupt the thread list in static executables.
Several previous changes conspired to make a mess of the thread list
in static binaries. This was most obvious when trying to call
pthread_key_delete(3) on the main thread.
