Implement persistent history storage:
the strategy is simple at start: loads the existing .sh_history file
at exit dump it.
The implementation respects the HISTFILE variable and its POSIX
definition: ~/.sh_history is used if HISTFILE is not set.
to avoid sh to create the history file, set HISTSIZE to 0 or HISTFILE to
en empty value

Without this patch, sh can autocomplete file names but not commands from
$PATH. Use libedit's facility to execute custom function for autocomplete,
but yield to the library's standard autocomplete function when cursor is
not at position 0.

The POSIX sh case statement does not allow for pattern matching using the

The following situation can trigger the deadlock:
1) Long time ago a_service was started through rc.d
2) We want to restart a_service and issue service a_service restart
3) rc.subr reads current process PID (via file or process),
sends TERM signal and runs pwait with PID harvested
4) a_service process dies very quickly so it's PID becomes available.
It is possible that while original process was running,
PID counter overflowed and pwait got assigned a_service's PID.
This patch ignores pid(s) to wait that are equal to pwait PID.

PR252358 reported a serious performance problem when
copying a large non-sparse file on a UFS file system.
This problem seems to have been caused by a large
number of SEEK_HOLE operations, with one done
for each copy_file_range(2) call.
This patch modifies cp(1) to use a large (SSIZE_MAX)
len argument, reducing the number of system calls
and resolving the performance issue.
While here, convert the type of the "rcount" from "int"
to "ssize_t" so that it is consistent with that returned
by both read(2) and copy_file_range(2).

This change has been motivated by a mail from bde sent in 2015 in
which he mentioned inappropriate use of sscanf() in 3 programs in
/bin.
This change removes the potential mismatch of the types of the return
values and the variable width specified in the scan pattern. While
there was no issue with the patterns and types used, the new code is
simpler and more efficient.
The previous version normalized the width list (replaced empty fields
with "0") just to be able to use sscanf() on the string.
It is much simpler to just parse the string as-is.
The clearing of f_notabs is preserved for the case that less than 9
width values have been defined, but I do not understand the rationale
for this particular condition. E.g., LS_COLWIDTHS="::::::::" will be
counted as 9 defined fields (may clear f_notabs) but is no different
fron LS_COLWIDTHS="" with regard to the field width (and that does not
clear f_notabs, since there are less than 9 fields).
This is addressing cases such as fts_read(3) encountering an [EIO]
from fchdir(2) when FTS_NOCHDIR is not set. That would otherwise be
seen as a successful traversal in some of these cases while silently
discarding expected work.
As noted in r264201, fts_read() does not set errno to 0 on a successful
EOF so it needs to be set before calling it. Otherwise we might see
a random error from one of the iterations.
gzip is ignoring most errors and could be improved separately.

The acl_from_stat function accepts a stat_t * argument, but only uses its
st_mode field. There is no reason to pass the whole struct, so make it accept
a mode_t and rename the function to acl_from_mode.
Linux has non-standard acl_from_mode function in its libacl, so naming the
function this way may help discovering it during porting efforts.
