4d9f97b40b [libc++] Don't return uninitialized data from random_device::operator()
Make sure we appropriately retry calls to read if the return result is
less than what we asked for.

Additionally, check and handle IO errors: EINTR results in the read
operation getting restarted; other errors turn into exceptions.

8db32cc2ac [libc++] random_device fails if open returns zero
random_device::random_device(const string&) wrongly assumes that open
can only validly return a file descriptor greater than zero.

This results in random_device believing that it didn't successfully open
the device causing it to throw in it's constructor, this ends up leaking
a file descriptor.

The fix is simple, don't error on file descriptors which are zero.

997e454139 Solaris port. Currently sees around 200 test failures, mostly related to
Solaris not providing some of the locales that the test suite uses.

Note: This depends on an xlocale (partial) implementation for Solaris and a
couple of fixed standard headers.  These will be committed to a branch later
today.
