shells/pbosh: Update to 20191205

Based on Schily Tools Release 2019-12-05.

AN-2019-11-11:
-   libschily: the new functions wcastoi wcastol wcastolb that have been
    added with the previous release have been forgotten in the linker map
    file.

AN-2019-12-05:
-   include/schily/stdio.h: We no longer define getc_unlocked() on Solaris
    in case that it is defined already. This was needed since Oracle
    Solaris 11.4 compiles 64 bit by default and made stdio less opaque
    than before - this result in the same bahavior as for 32 bit programs.
    This means, we no longer need to use tricks to get fast access to
    stdio.

    Thanks to Rolf Dietze for reporting.

-   libschily: the function getargs() and similar (from the option parser
    group) fixed a bug that prevented the usability of the official method
    to include the char '+' inside option names by quoting the character
    in the option name used in the format string.

    This bug has been fixed in order to be able to support "star -dump+ \ 
..."

-   libshedit: because of the changes in Oracle Solaris 11.4, we need to
    #undef FAST_GETC_PUTC in order to avoid to use getc_unlocked().

    Thanks to Rolf Dietze for reporting.

-   Bourne Shell/bsh: */hashcmd.c did not handle a malloc()ed string
    correctly and could cause a memory leak with hash commands that
    do not add new aliases.

    We now create a copy using make()/makestr() before calling ab_push()
    or ab_insert() and always free "name" at the end of the function
    hashcmd()

-   Bourne Shell: The man page now documents that the command

        "set -o hashcmds"

    inside the file $HOME/.shrc makes a # on the fist column of that
    file and followed by a non-space character, no longer a comment..
    It is thus recommended to have "set -o hashcmds" close to the.
    bottom of the file $HOME/.shrc
