0707b67ac3 Handle partial nanosleeps in this_thread::sleep_for 
Signals may result in nanosleep returning with only some of the
requested sleeping performed.

Utilize nanosleep's "time-remaining" out parameter to continue sleeping
when this occurs.

e39915bdc5 Fix XFAIL condition from r208840 
The XFAILs in r208840 were too general. They were meant to only apply
to testing when use_system_lib was set.

5fda8338b2 Work around ABI differences due to LWG 2056 in tests 
When testing against the system library, there is a relatively minor
ABI breakage that the std::future_errc values have been changed to
avoid using zero. Update the tests that rely on the values being
consistent.

f9f95be930 Implement N3891: A proposal to rename shared_mutex to shared_timed_mutex 
This is as straightforward as it sounds, a renamed from shared_mutex to
shared_timed_mutex.

Note that libcxx .dylib and .so files built with c++14 support need to
be rebuilt.

9976b5511a This is a start at making the libc++ test suite friendlier to the -fnoexceptions flag. Although this is not a complete solution, it does reduce the number of test failures on OS X from 467 to 128 on OS X when -fno-exceptions is enabled, and does not impact the number of failures at all when -fno-exceptions is not enabled. The bulk of this code was donated anonymously.

76aa2ef017 Fix a bug in mutex_try_to_lock. This was previously trying to unlock a mutex that it didn't own, causing an assertion failure in mutex.cpp. The issue was that the unique_lock went out of scope, releasing the lock on m, then m.unlock() was called on an already-unlocked mutex. 
This change removes the spurious m.unlock() call.  

If this test was previously passing for anyone with assertions enabled, then they should investigate bugs in their pthread implementation, as pthread_unlock() should not return 0 if the mutex is currently unlocked.

fe14b970ac [tests] Increase a bunch of wait limits. 
- Basically I just ran the thread tests many many times on a busy machine and
   bumped the timeouts whenever I hit a test failure.

 - This is obviously subpar, but is the best I can do without the tests being
   rewritten to not depend on arbitrary timeouts.
