In order to support gpart(8), geom(8) needs to support a named
argument. Also, optional string parameters are a requirement.
Both have been added to the infrastructure. The former required
all existing classes to be adjusted.

o Implement automatic commit. It's enabled when the flags parameter
exists and contains the 'C' flag.
o The partition label can be the empty string. It's how labels are
cleared.
o When an action fails, lower permissions when they were raised
in order to allow the action. A failed action will not result
in any uncommitted changes.
o Allow the flags paremeter to be present but empty. It's the
equivalent of not being present.

Rework the support for ABIs to override resource limits (used by 32-bit
processes under 64-bit kernels). Previously, each 32-bit process overwrote
its resource limits at exec() time. The problem with this approach is that
the new limits affect all child processes of the 32-bit process, including
if the child process forks and execs a 64-bit process. To fix this, don't
ovewrite the resource limits during exec(). Instead, sv_fixlimits() is
now replaced with a different function sv_fixlimit() which asks the ABI to
sanitize a single resource limit. We then use this when querying and
setting resource limits. Thus, if a 32-bit process sets a limit, then
that new limit will be inherited by future children. However, if the
32-bit process doesn't change a limit, then a future 64-bit child will
see the "full" 64-bit limit rather than the 32-bit limit.
MFC is tentative since it will break the ABI of old linux.ko modules (no
other modules are affected).

Move cpu_exit() earlier in exit1() to close a race between
SIGCHLD/kevent(2) notification of process termination and wait(). Now
we no longer drop locks between sending the notification and marking
the process as a zombie. Previously, if another process attempted to do
a wait() with W_NOHANG after receiving a SIGCHLD or kevent and locked
the process while the exiting thread was in cpu_exit(), then wait() would
fail to find the process, which is quite astonishing to the process
calling wait().

Use unsigned comparisons. Prior to this commit, SHA1_Update and
RIPEMD160_Update were broken when all of the following conditions
applied:
(1) The platform is i386.
(2) The program calling *_Update is statically linked to libmd.
(3) The buffer provided to *_Update is aligned modulo 4 bytes.
(4) The buffer extends beyond 2GB.
Due to the design of this code, SHA1_Update and RIPEMD160_Update will
still be broken if conditions (1)-(3) apply AND the buffer extends
beyond 4GB (i.e., there is an integer overflow in computing "data + len").
Since this remaining bug simply replaces SIGSEGV with a bogus hash (and
non-broken programs should never provide such operands) I don't consider
it to be a serious problem.

Improve INCLUDE_CONFIG_FILE support.
This change will let us to have full configuration of a running kernel
available in sysctl:
sysctl -b kern.conftxt
The same configuration is also contained within the kernel image. It can be
obtained with:
config -x <kernelfile>
Current functionality lets you to quickly recover kernel configuration, by
simply redirecting output from commands presented above and starting kernel
build procedure. "include" statements are also honored, which means options
and devices from included files are also included.
Please note that comments from configuration files are not preserved by
default. In order to preserve them, you can use -C flag for config(8). This
will bring configuration file and included files literally; however,
redirection to a file no longer works directly.
