This is useful in environments where system configuration is performed by
automated interaction with the system console, since unexpected witness
output makes such automation difficult. With this change, the new
debug.witness.output_channel sysctl allows one to specify that witness
output is to be printed to the kernel log (using log(9)) rather than the
console.

This fixes building objects directly, or skipping 'make depend', not generating
required headers first. This case did work without FAST_DEPEND so there's no
reason it should not work here as well.
An example of this can be seen building in gnu/usr.bin/binutils/libbfd

When the M_NOWAIT allocation fails, we recurse the if_addr_lock trying
to clean up. Reorder the cleanup after dropping the if_addr_lock. The
obvious race is already possible between if_addmulti and IF_ADDR_WLOCK
above, so it must be ok.

trying to do a mount. Given the backtrace,
it appears that the crash occurred when smb_vc_create() failed and then
called smb_vc_put() with vcp->vc_iod == NULL. smb_vc_put() subsequently
called smb_vc_disconnect() with vcp->vc_iod == NULL, causing the crash.
This patch adds a check for vcp->vc_iod != NULL in smb_vc_disconnect() to
avoid the crash. It also fixes the case in smb_vc_create() where
kproc_create() fails so that it destroys the mutexes and sets
vcp->vc_iod == NULL before free()'ing the iod structure.
The person who reported the PR tested the patch, but was not able
to reproduce the crash with or without the patch.

The _SKIP_BUILD is used while computing DIRDEPS. If MACHINE=host is passed in
then this logic was replacing 'MACHINE' with a literal value of the host arch,
which then caused the dirdeps graph to be wrong since it no longer had the
literal 'host' for any of include's dependencies.
This is a NOP currently since include/ is not usually built with MACHINE=host.

The bootstrap-tools are supposed to be host tools, which in most cases, use
host headers and libraries. As such, directly including the src tree's headers
for libmd here causes the need to link libmd in since it will be built with
the new symbols (which /usr/lib/libmd.so) won't have unless it is new enough.
During the target build in buildworld the target headers are staged into
WORLDTMP and used via --sysroot, allowing the target xinstall to be built with
the new/target libmd.
The .PATH here was also not doing anything since xinstall does not use libmd
source files.

pmcstat(8) contains an option to output sampling data in a gmon format
compatible with gprof(1). Currently, it uses the default histcounter,
which is an (unsigned short). With large sets of sampling data, it
is possible to overflow the maximum value provided by an (unsigned
short).
This change adds the -e argument to pmcstat. If -e and -g are both
specified, pmcstat will use a histcounter type of uint64_t.
