pbosh: update to 20190311.

Update provided by Michael Bäuerle via pksrc-wip.

Changelog
=========

Release 2019-02-18:
- libgetopt: The undocumented variable "_sp" from SVr4 has been renamed
             to "opt_sp" and (on platforms that support "#pragma weak") there
             is a  weak reference _sp to that new variable, giving backwards
             compatibility.

             The reason for doing this is to make sure that people on Illumos
             or Oracle Solaris, who still have an outdated version of getopt()
             in their local libc, do not try to link the Bourne Shell only
             against their old getopt(). If they did this, they would not get
             the documented enhanced getopt() features from the Bourne Shell.

- Bourne Shell: The shell now uses "opt_sp" as the name for the
                undocumented additional getopt() interface from AT&T. This has
                been done to avoid being able to link the Bourne Shell on
                Illumos or Oracle Solaris without using our libgetopt. If this
                was done, we could not support UNIX/MULTICS style long options
                and we could not support -help/--help, since the latter is
                implemented via long options that are not an alias to short
                options.

- Bourne Shell: added a new timestamp to the Bourne Shell version.


Release 2018-11-21:
- Bourne Shell: make it exit the whole shell with set -e after a command
                substitution failed on the right side of a variable assignment
                that has no command. This is required by POSIX.

- Bourne Shell: added a unit tests for the above case.

- Bourne Shell: New version date set to 2018-12-08 the this change.

Release 2019-01-22:
- bsh / Bourne Shell / star: the function hop_dirs() no longer checks
                             for p2 != NULL before calling *p2 = '/' as p2 has
                             been granted to be != NULL from a break with
                             strchr(p, '/') == NULL

                             Thanks to Pavel Raiskup for poiting to a related
                             Coverity message.

- Bourne Shell: Added a missing /* FALLTHROUGH */ comment..

                Thanks to Pavel Raiskup for poiting to a related Coverity
                message.

- Bourne Shell: added a range check for $OPTIND to tge getopts(1)
                implementation

                Thanks to Pavel Raiskup for poiting to a related Coverity
                message.

- Bourne Shell: Removed a nonsense variable in expand() that caused
                Coverity not to understand that a directory was correctly
                closed()

                Thanks to Pavel Raiskup for poiting to a related Coverity
                message.

- Bourne Shell: Added a paranoia comparison to make Coverity quiet.

                Thanks to Pavel Raiskup for poiting to a related Coverity
                message.

- Bourne Shell: avoid to call catpath() with a NULL pointer for path

                Thanks to Pavel Raiskup for poiting to a related Coverity
                message.

- Bourne Shell: check the write() return code in io.c

                Thanks to Pavel Raiskup for poiting to a related Coverity
                message.

- Bourne Shell: Added a paranopia check for "test -o" to make Coperity
                quiet.

                Thanks to Pavel Raiskup for poiting to a related Coverity
                message.

- Bourne Shell: Added (void) before fcntl() in hope to make Coverity
                quiet.

                Thanks to Pavel Raiskup for poiting to a related Coverity
                message.

- Bourne Shell: Removed dead code from readwc()

                Thanks to Pavel Raiskup for poiting to a related Coverity
                message.

- Bourne Shell: Cstyle changes to xec.c

- Bourne Shell: "builtin -d ..." did access free()d memory.

                Thanks to Pavel Raiskup for poiting to a related Coverity
                message.

- Bourne Shell: expand.c: added a check for fd == -1 to avoid calling
                openat() with that fd.

                Thanks to Pavel Raiskup for poiting to a related Coverity
                message.

-Bourne Shell: func.c: added a check for fd == -1 to avoid calling
               read()/close() with that fd.

                Thanks to Pavel Raiskup for poiting to a related Coverity
                message.

- Bourne Shell: jobs.c: enlarged a buffer to be of same size as
                numbuf[] to avoid a potential buffer overflow.

                Thanks to Pavel Raiskup for poiting to a related Coverity
                message.

- Bourne Shell: print.c::prt_cntl() had a very old (AT&T) bug with
                printing byte sequences that get an error with mbtowc() and it
                did not print byte sequences correctly that refer to legal but
                "nonprintable" multi byte characters.

                Thanks to Pavel Raiskup for poiting to a related Coverity
                message.

- Bourne Shell: xec.c: the reserved word "time" could cause to
                access uninitialized memory if the string in $TIMEFORMAT
                contains the format %J

                Thanks to Pavel Raiskup for poiting to a related Coverity
                message.

- Bourne Shell: xec.c: added a paranoia check on whether
                findnam("funcname") returns NULL even though the existence of
                a function with that name already has been verified via the
                hash service.

                Thanks to Pavel Raiskup for poiting to a related Coverity
                message.

Release 2019-02-18:
- Bourne Shell: Another vfork() problem has been fixed. "trap cmd EXIT"
                has incorrectly called "cmd" after a non-existing command was.
                called by the shell. This was a result of the shared data from
                vfork().

                Thanks to Martijn Dekker for reporting.

- Bourne Shell: A unit test case for the above bug has been added.

- Bourne Shell: __growstak() now always uses realloc() on modern
               platforms. This may speed up things up to 15%.

               Thanks to Jan Engelhardt for reporting.

Release 2019-03-11:
- libgetopt/Bourne Shell: added an #ifndef __CYGWIN__ in order to avoid
                          overwriting non-standard definitions by standard
                          definitions on Cygwin for the global getopt()
                          variables.

                          Thanks to Heiko Ei[eszett]feldt for proposing this
                          fix.

- Bourne Shell: better comment in bltin.c
