to hold the malloc lock across mmap syscalls in all cases. dropping it
allows another thread to access the existing chunk cache if necessary.
could be improved to be a bit more aggressive, but i've been testing this
simple diff for some time now with good results.
This enables support for the new getrandom(2) syscall in Linux 3.17.
If the call exists and fails, return a failure in getentropy(2) emulation as
well. This adds a EINTR check in case the urandom pool is not initialized.
Tested on Fedora Rawhide with 3.17rc0 and Ubuntu 14.04

circular lists. Amazingly, they managed to extend the requirements to no
longer match the behavior of the VAX instructions they were modeled after,
so the trivial VAX ASM versions have to go. Nice job breaking it, X/Open!

Most assembly blocks remain inactive if OPENSSL_NO_ASM is not defined,
only enabling inline assembly, but the RSA / RC4-5 blocks (used only in
amd64 systems) turn on implicitly. Guard these two as well.
This simplifies enabling just inline ASM in portable, no effective
change in OpenBSD.
the details are under embargo. The original plan was to wait for the
embargo to lift, but we've been waiting for quite some time, and there's no
indication of when or even if it will end. No sense in dragging this out
any longer.
The SRP code has never been enabled in OpenBSD, though I understand it is
in use by some other people. However, in light of this and other issues,
we're officially saying SRP is outside the scope of libressl. (For now.)
Move <sys/mman.h> and raise(SIGKILL) calls to OS-specific headers.
On OpenBSD, move thread_private.h as well to arc4random.h.
On Windows, use TerminateProcess on getentropy failure.

6.11.5 - Storage-class specifiers:
The placement of a storage-class specifier other than at the
beginning of the declaration specifiers in a declaration is
an obsolescent feature.

it shows up in libraries. Even the system call is probably not finalized.
Bit dissapointed it has turned out to be a descriptor-less read() with
EINVAL and EINTR error conditions, but we can work with it.
into one if a system has an awesome getentropy(). In that case it
is valid to totally throw away the rsx state in the child. If the
getentropy() is not very good and has a lazy reseed operation, this
combining is a bad idea, and the reseed should probably continue to
use the "something old, something new" mix. _rs_allocate() can
accomodate either method, but not on the fly.

1. Use "len" parameter instead of sizeof(*rs).
2. Simplify the atfork handler to be strictly async signal safe by
simply writing to a global volatile sig_atomic_t object, and then
checking for this in _rs_forkdetect(). (Idea from discussions with
Szabolcs Nagy and Rich Felker.)
3. Use memset(rs, 0, sizeof(*rs)) to match OpenBSD's MAP_INHERIT_ZERO
fork semantics to avoid any skew in behavior across platforms.

into the hash; hoping the system has some ASLR or PIE. This replaces and
substantially improves upon &main which proved problematic with some picky
linkers.
