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.

Committing early to make sure we have time to fix any side-effect.

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!

if it's invoked without parameters. It's simpler than adding adding
/etc/rc.conf and /etc/rc.conf.local parameters whereever _rc_parse_conf
is used (e.g. /etc/rc and /etc/netstart).
While here, replace a

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.

a "location" is just a special type of a "virtual" server.

The option "directory auto index" implements basic directory listing
and is turned off by default.

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.
