Add an internal _once() method. This works identical to pthread_once(3)
with the additional property that it is safe for routines in libc to use
in both single-threaded and multi-threaded processes. Multi-threaded
processes use the pthread_once() implementation from the threading library
while single-threaded processes use a simplified "stub" version internal
to libc.
Add a new errno, ENOTCAPABLE, to be returned when a process requests an
operation on a file descriptor that is not authorized by the descriptor's
capability flags.

Update to BIND 9.6.1-P2. The vulnerability this is designed to fix is
related to DNSSEC validation on a resolving name server that allows
access to untrusted users. If your system does not fall into all 3 of
these categories you do not need to update immediately.
- fix a transfer cancelling bug/segfault [1]
- correct a return code in the transfer cancel function.

Not all Intel Core (TM) CPUs implement PMC_CLASS_IAF fixed-function
counters. For such CPUs, use an alternate mapping of convenience
names to events supported by PMC_CLASS_IAP programmable counters.
Add two new fcntls to enable/disable read-ahead:
- F_READAHEAD: specify the amount for sequential access. The amount is
specified in bytes and is rounded up to nearest block size.
- F_RDAHEAD: Darwin compatible version that use 128KB as the sequential
access size.
A third argument of zero disables the read-ahead behavior.
Please note that the read-ahead amount is also constrainted by sysctl
variable, vfs.read_max, which may need to be raised in order to better
utilize this feature.
Thanks Igor Sysoev for proposing the feature and submitting the original
version, and kib@ for his valuable comments.
The fd_mask type is an unsigned long, not an int, so treat the mask as a
long instead of an int when examining the results of select() to look for
RPC requests. Previously this routine would ignore RPC requests to sockets
whose file descriptor mod 64 was greater than 31 on a 64-bit platform.
* retry various system calls on EINTR
* retry the rest after a short read (common if there is more than about 1K
of output)
* block SIGCHLD like system(3) does (note that this does not and cannot
work fully in threaded programs, they will need to be careful with wait
functions)

Eliminate dead stores.
In __mbsconv(), if prec was zero, nconv could have been used
uninitialized. Initialize it to a safe value so that there's no
chance of returning an error if stack garbage happens to be equal to
(size_t)-1 or (size_t)-2.
In svc_raw_reply(), don't leave stat uninitialized if the MSG_ACCEPTED
&& SUCCESS case succeeds. The stack garbage might be zero.
In clnt_raw_create(), avoid minor race condition initializing the
file-scope variable clntraw_private.

Add simple embedded RADIUS server support to libradius, by extending existing
API, keeping backward compatibility.
First consumer for this functionality is going to become forthcoming MPD-5.4,
supporting CoA and DR of RFC 3576: Dynamic Authorization Extensions to RADIUS.
Make libc.a provide __stack_chk_fail_local weak alias. This is
needed to satisfy static libraries that are compiled with -fpic
and linked into static binary afterwards. Several libraries in
gcc are examples of such static libs.

cr_groups is no longer embedded in struct ucred and is instead stored
in a seperate array. As such we need to use kvm_read rather than bcopy

Let fall down in the hard path (thus handling shared waiters wakeup
correctly) for the shared waiters also in the rwlock held in shared mode
as well, fixing possible deadlocks.
Please note that this is a special condition as we want this fix in
before RC2 as we assume it is critical and so it has been handled
as an instant-merge. For the STABLE_7 branch, 1 week before the MFC

(incorrect handling of zero-length reads before the copy buffer is
allocated) is masked by the iso9660 taster. Tar and cpio both enable
that taster so were protected from the bug; unzip is susceptible.
This both fixes the bug and updates the test harness to exercise
this case.
