GetMainExecutable yet.

7abb8df743 Apply a patch from Kees van Reeuwijk to add support for Minix. 
Minix apparently doesn't like double-slash separators, and there's
no apparent need for them here.

093ad188e7 CrashRecovery/Darwin: On Darwin, raise sends a signal to the main thread instead 
of the current thread. This has the unfortunate effect that assert() and abort()
will end up bypassing our crash recovery attempts. We work around this for
anything in the same linkage unit by just defining our own versions of the
assert handler and abort.

b0f45f192c Rather than using an ifdef on the target to zero out fields, 
just use memset to zero the entire struct.

b049874698 Factor out the handler work from SignalHandler into a helper function, 
and change llvm::sys::RunInterruptHandlers to call that function directly
instead of calling SignalHandler, because the rest of SignalHandler
invokes side effects which aren't appropriate, including raising the
signal.

152b2bc046 This is horrible. Split the difference, and declare 'environ' on all non-Darwin 
platforms to unbreak the darwin and linux builds. The BSD folks should feel
free to change the #if, if this breaks them.

22b58ac393 make Program::Execute use posix_spawn on systems that support it, 
as it is more efficient than fork/exec.

Thanks to Eric for adding the autoconf check.  It would be nice if
a cmake guru could add a cmake check for posix_spawn as well.

58964f4bee Fix a false-positive memory leak in code using RemoveFileOnSignal(). Because 
libstdc++'s std::string class points to the interior of an allocation, valgrind
reports strings still alive at program termination as possible leaks.  I didn't
use a ManagedStatic for this because System can't depend on Support.

46925cc515 Fix TimeValue::now() on Unix. 
TimeValue()::now().toEpochTime() is supposed to be the same as time(),
but it wasn't, because toEpoch subtracted PosixZeroTime, but now()
didn't add PosixZeroTime!
Add a unittest to check this works.

435a9894a7 This patch ensures that Path::GetMainExecutable is able to handle the 
case where realpath() fails. When this occurs we segfault trying to
create a std::string from a NULL pointer.

b9ff937285 Use 'waitpid' instead of 'wait'. Basing Program::Wait() on 'wait()' prevents it being correct within a multithreaded context. 
This address: PR 5277 (Program::Wait is unsafe to call from multiple threads).

Note: If waitpid() turns out to be non-portable, we can add more autoconf magic, or look into
another solution.
