During the update process in sa_modify_attrs(), the sizes of existing
variably-sized SA entries are obtained from sa_lengths[]. The case where
a variably-sized SA was being replaced neglected to increment the index
into sa_lengths[], so subsequent variable-length SAs would be rewritten
with the wrong length. This patch adds the missing increment operation
so all variably-sized SA entries are stored with their correct lengths.
Another problem was that index into attr_desc[] was increased even when
an attribute was removed. If that attribute was not the last attribute,
then the last attribute was lost.
The variable isn't actually checked -- just the end result which gets
returned from the function

bash lacks the ksh93 optimization that makes sub-shells fast if they do
not alter io. bash 3.1-alpha1 introduced printf -v var_to_set which is not
as fast but is still significantly faster than var_to_set=$( printf ) when
using any version of bash. If we find our interpreter to somehow be bash
by invocation or inclusion, use the feature that provides fastest results.
"make kernels" is now shorthand for "make universe -DMAKE_JUST_KERNELS"
"make worlds" is now shorthand for "make universe -DMAKE_JUST_WORLDS"
The kernels target includes modules (unless you add -DNO_MODULES).
And of course you can still add all the other universe options, such as
"make kernels TARGETS=arm" to build kernels for all arm arches, or
TARGET_ARCH=armv6 to build all armv6 kernels, etc.

print until cncheckc returned a non -1, i.e. a character had been entered.
After this change it would print only if cncheckc returned a character.
As this was before each call to db_mach_vtrace the normal outcome was
nothing was printed.
With this change 'show ktr /a' will now keep printing until the user stops
the command with a key press, or there is no more entries to print.

embedded structures out of a packed, unaligned struct into local copies
on the stack which are aligned.
The original patch to do this was submitted by Guy Yur <guyyur@gmail.com>,
and this is conceptually the same change, but restructured with the
#ifndef __NO_STRICT_ALIGNMENT wrapper, similar to how the same issue is
handled in the kernel pf code.

Builtins (including variable assignments without command word), function
calls and redirected compound commands need to restore file descriptors
to their original state after execution. This is handled by allocating a
redirtab structure. These mallocs and frees show up heavily in pmcstat.
Only allocate a redirtab if there are actually redirections and maintain a
count of how many levels of REDIR_PUSH there are without redirtabs.
A simple loop without external programs like
sh -c 'i=0; w=$(printf %0100d 7); while [ "$i" -lt 1000000 ]; do
i=$((i+1)); done'
is over 25% faster on an amd64 bhyve VM.
The linear search using strcmp() shows up in pmcstat for several percent.
Split the operators into lengths and whether they start with '-' and compare
bytes using == instead of strcmp().
A simple test
sh -c 'i=0; w=$(printf %0100d 7); while [ "$i" -lt 1000000 ]; do
v=$(printf %sx%s "$w" "$w"); i=$((i+1)); done'
is over 4% faster on an amd64 bhyve VM.
Some of the structures referenced in power.c (in particular
struct nvme_power_state) are missing from sbin/nvmecontrol/
