2dfdfdf45c [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.

1e9592a9c7 [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.

1f393c3eaf Remove XFAIL from a number of tests that aren't expected to fail 
These tests haven't been failing on darwin11 or 12 since r189610 when
pr17027 was fixed, but they've been keeping the libc++ bot red by
XPASSing since then.

a429ba738c Back out the <type_traits> changes from r198431; they were breaking when building with glibc. Need to find a better solution for PR18218.

d41295da72 Patch by Howard. First part of fix for PR18218; add type traits needed to do the right thing. Fix the problems in PR18218 for isnan and pow - they also need to be applied to the other functions in <cmath>. Also, a drive-by fix for the test - now actually calls test_abs()

a60ae88db2 Marshall Clow found some divide-by-zero warnings with UBSan in rand's binomial_distribution test. This eliminates the divide-by-zeros and describes in comments the numerical difficulties the test is having. Each of the problematic tests are exploring edge cases of the distribution.

00d8c245b2 Reimplemented much of <istream> such that single character extractions do not check to see if this is the last character in the stream and thus never set eofbit. This fixes http://llvm.org/bugs/show_bug.cgi?id=10817 . This fix requires a recompiled libc++.dylib to be fully implemented. The recompiled libc++.dylib is ABI compatible with that shipped on Lion.

b4d2fd2f0f [rand.dist.samp.plinear]. This means we've got a fully tested and functional <random>! 489 tests over 48 sections are passing. :-) The only thing still on my plate in this area is to back-port some of this technology to random_shuffle/shuffle in <algorithm>. That will involve shuffling header bits around (<random> depepends on <algorithm>), but it won't entail that much development (compared to what has been required for <random>).
