d4dcb70287 Don't restrict ourselves to a "max" fd when closing fds before exec() 
when we have a way to get an actual list of all open fds from the OS.

Fixes issue #21618: The subprocess module would ignore fds that were
inherited by the calling process and already higher than POSIX resource
limits would otherwise allow.  On systems with a functioning /proc/self/fd
or /dev/fd interface the max is now ignored and all fds are closed.

efeb9da4ae Add conditional code for android's lack of definition of SYS_getdent64. 
Fixes issue20307.  No Misc/NEWS entry because frankly this is an
esoteric platform for anyone to be figuring out how to cross compile
CPython for.

54532c9742 Undo supposed fix for Issue #15798 until I understand why this is 
causing test_multiprocessing_forkserver and test_multiprocessing_spawn
failures on head (3.4).

daf455554b Issue #18571: Implementation of the PEP 446: file descriptors and file handles 
are now created non-inheritable; add functions os.get/set_inheritable(),
os.get/set_handle_inheritable() and socket.socket.get/set_inheritable().

8d07c264e4 Raise our own SubprocessError rather than a RuntimeError in when dealing with 
odd rare errors coming from the subprocess module.

a10ddb8a55 Fixes Issue #16114: The subprocess module no longer provides a 
misleading error message stating that args[0] did not exist when
either the cwd or executable keyword arguments specified a path that
did not exist.

5591b02a4c Fixes Issue #16114: The subprocess module no longer provides a 
misleading error message stating that args[0] did not exist when
either the cwd or executable keyword arguments specified a path that
did not exist.

It now keeps track of if the child got as far as preexec and reports it if
not back to the parent via a special "noexec" error message value in
the error pipe so that the cwd can be blamed for a failed chdir
instead of the exec of the executable being blamed instead.

The executable is also always reported accurately when exec fails.

Unittests enhanced to cover these cases.
