1bdbd70599 Implement process-shared locks support for libthr.so.3, without
breaking the ABI.  Special value is stored in the lock pointer to
indicate shared lock, and offline page in the shared memory is
allocated to store the actual lock.

(when they actually get committed, that is), and might also come in handy

cd1832fe92 Reorganize the handling all-zeroes terminal block in sparse mode
The intent of the previous code in that case was to force
an explicit write, but the implementation was incorrect, and
as a result the write was never performed. This new implementation
instead uses ftruncate(2) to extend the file with a trailing hole.

Also introduce regression tests for these cases.

ac2875fa16 Explicitly add unmarked bin/ binaries to the runtime package.
Note: tcsh(1) has a MK_TCSH=no test, so this should be a separate

The symbols of libiconv from ports were changed to
have prefixed.
Since we have iconv in our libc these days, we don't
need it on 10.X and later.  However, 9.X still need
this.

bd9b38d1f7 sh: Don't allocate a redirtab if there are no redirections.
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.

f1602fa511 test: Optimize operator lookup.
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.
