Fix a bug in bsdgrep that caused the program to hang in a tight loop for
some combinations of command line options and search patterns. The code was
examining regexec flags looking for a regcomp flag value. The fix is to
look in the struct field where the decoded regcomp flag was stored when the
regex was compiled.
With this fix, it's possible to build WITHOUT_GNU_GREP_COMPAT and
WITH_BSDGREP and have a usable GPL-free grep (which of course lacks gnugrep
extensions). It now passes the kyua tests except for one test that requires
the -z/--null-data gnu extension, and one test involving outputting context
lines across multiple files which appears to sometimes output an extra
delimiter line ("--") between matches (a rather obscure failure of a rather
obscure feature, so bsdgrep should be generally usable now).
Remove name length limitation from autofs(5). The linear search with
strlens is somewhat suboptimal, but it's a temporary measure that will
be replaced with red-black trees later on.

Do not include system call wrappers in libc for old FreeBSD system calls.
The base system libc is only used to run binaries built on FreeBSD 7.0 and
later. It does not need to include system call wrappers for system calls
only used by FreeBSD binaries built on versions older than 7.0. This was
already true for "COMPAT" system calls, but now wrappers for system calls
used on FreeBSD 4 and 6 are excluded as well.
This makes sure the default context of each ring is cleaned up with the
ring itself and fixes a memory leak.

drm/i915: unreference default context on module unload
Before module unload is called, gpu_idle() will switch
to default context. This will increment ref count of base

time. Unreference the drm object so that when context
is freed, base object is freed as well.

Fix autofs triggering problem. Assume you have an NFS server,
192.168.1.1, with share "share". This commit fixes a problem
where "mkdir /net/192.168.1.1/share/meh" would return spurious
error instead of creating the directory if the target filesystem
wasn't mounted yet; subsequent attempts would work correctly.
The failure scenario is kind of complicated to explain, but it all
boils down to calling VOP_MKDIR() for the target filesystem (NFS)
with wrong dvp - the autofs vnode instead of the filesystem root
mounted over it.

This obsoletes the _SKIP_BUILD check but keeps it for now until it

'make dirdeps' which builds dependencies and then builds the current

dirdeps phase AND the sub-make phase which creates all kinds of problems

DIRDEPS_BUILD: Avoid rebuilds due to changed build commands with newly staged tools.
This is a follow-up to r291561 which reworked the bootstrap tool PATH
handling.
An example of this is when building lib/clang/libclangedit. At first
clang-tblgen will not be staged in the host tree so it will have
CLANG_TBLGEN=clang-tblgen set and exported. During the build though it
will stage clang-tblgen and then find it via the PATH. On the next
build it finds clang-tblgen in the stage directory and would set
CLANG_TBLGEN=<stagedir/usr/bin>/clang-tblgen thus causing the build
command to change. In both cases the same exact tool was used though so
there is no need to rebuild. If the tool did change the normal
meta/filemon handling would pick that up via timestamp comparisons and
rebuild.

Fix various GCC mis-configurations for newer versions.
This patch goes through and enables C++11 and C++14 features for newer GCC's.
The main changes are:
1. Turn on variable templates. (Uses __cpp_variable_templates)
2. Assert atomic<Tp> is trivially copyable (Uses _GNUC_VER >= 501).
3. Turn on trailing return support for GCC. (Uses _GNUC_VER >= 404)
4. XFAIL void_t test for GCC 5.1 and 5.2. Fixed in GCC 6.
Together, these should fix building clang 3.8.0 as part of building

ports).

- Try to guess what is provided as a pin spec for -t or for get/set

- Add -p and -N switches to force pin specification interpretation:
-p forces spec to be pin number, -N forces it to be name
Do not perform unneccessary shared recursion on the allproc_lock in

FAST_DEPEND: Use .dinclude to enable full .depend logic in bmake.
The inclusion of .MAKE.DEPENDFILE (.depend) has special logic in make

directive that uses the special logic for .depend when including the file.
This fixes a build error when a file is moved or deleted that exists in a
.depend.OBJ file. This happened in r292782 when sha512c.c "moved" and an
incremental build of lib/libmd would fail with:
make: don't know how to make /usr/src/lib/libcrypt/../libmd/sha512c.c. Stop
Now this will just be seen as a stale dependency and cause a rebuild:
make: /usr/obj/usr/src/lib/libmd/.depend.sha512c.o, 13: ignoring stale .depend for /usr/src/lib/libcrypt/../libmd/sha512c.c
--- sha512c.o ---
...
This rebuild will only be done once since the .depend.sha512c.o will
be updated on the build with the -MF flags.
This also removes -MP being passed for the .depend.OBJ generation (which
would create fake targets for system headers) since the logic is no
longer needed to protect from missing files.
