arm64: Add exception flag for ksiginfo_t and set in trapsignal
The `ksiginfo_t` flag `KSI_TRAP` is set both for exceptions and when
copying between userspace and the kernel fails. In the latter case, the
exception syndrome register as captured in `struct trapframe` won't be
valid. That means we can't use `KSI_TRAP` to determine whether `tf_esr`
is valid. This motivates the addition of a new flag, here called
`KSI_EXCEPT`, for specifically identifying signals caused by exceptions.
It is added to `ksi_flags` via `trapsignal`.

arm64: Expose ESR in mcontext
At present, the exception syndrome register (ESR) is not accessible via
the user context on FreeBSD AArch64, which makes it difficult to
determine the cause of an exception. For example, a signal handler might
get a `SIGSEGV` with `SEGV_ACCERR`, but it can't know whether that
occurred due to a bad read or write. The change implemented here
includes ESR in `struct __mcontext`, thereby allowing access via
`ucontext_t` for use by signal handlers, sanitizers, debuggers, etc.
Note that this addition consumes one of the seven spare 64-bit slots in
`struct __mcontext`.

bhyve(8): allow cpu pinning using N-M:X-Y ranges
bhyve's -p allows to pin guest's virtual CPU vcpu to hostcpu, however
this becomes very tedious work when you have to pin more than a single
CPU.
This allows to pass a range to -p, e.g. -p 0-3:4-7 which will pin the
cpus 0:4, 1:5, 2:6, 3:7. The ranges must be equal and the CPU numbers
must be ascending.

rc: Bail if /dev/null is not a device
On startup, check that /dev/null exists and is a character device.
Otherwise, one of two things will happen: either /dev is a writable
directory and we will immediately create /dev/null as a regular file
and dump garbage into it, or it does not and we will spit out a stream
of error messages about failing to create /dev/null.

etcupdate: Make nobuild the default
The common case for etcupdate is to run it after building and installing

Add a -b option to turn nobuild off (opposite of -B), and turn nobuild

fts: address post-merge feedback on fts_children_test.c
- Remove fts_check_debug() which is only needed by test cases
that use the fts_test() helper; fts_children_test.c does not
call fts_test()
- Remove fts_lexical_compar where traversal order does not matter
for the test result
- Drop fts_test.h and copy fts_lexical_compar locally

fts: address post-merge feedback on fts_set_test.c
Per review by des@:
- Remove fts_check_debug() which has no effect in fts_set_test.c, and
remove unused #include "fts_test.h"
- Add errno = 0 before fts_read() so errno check is meaningful
- Remove fts_lexical_compar where traversal order does not matter
- Change int boolean flags to bool throughout
- Use !saw_inside instead of saw_inside == false
- Move fts_set_clientptr/fts_get_clientptr test inside fts_read()
loop so the pointer is exercised during active traversal

nfsd: Add per-MDS fs striping configuration
Commit 72e57bc26417 added support for striping to the pNFS
server when using the Flexible File layout.
It is configured globally via the following sysctls:
vfs.nfsd.pnfsstripeunit - Size (in bytes) of a stripe
vfs.nfsd.pnfsstripecnt - # of DSs to stripe across
This patch allows the above settings to be overridden
on a per-MDS exported file system basis. With this
patch, a stripeunit can optionally be specified for
the MDS file system listed when one is listed after
a '#' in the "-p" nfsd argument. This is done by
appending "@NNN", where NNN is the stripeunit, in bytes.
The current syntax implies that neither a '#' nor '@'
can be in the MDS mount point's directory path.
This patch does not affect current pNFS server
