x11/xterm: update to 372

Patch #372 - 2022/03/09
    -amend allocation/freeing of scrollback lines, eliminating an adjustment for
    status-line added in patch #371 (report/testcase by Rajeev V. Pillai).

Patch #371 - 2022/02/24
    -drop double-buffer default from test-packages, since that interferes with
    status-line.
    -add faceSize7 to table in charproc.c, overlooked in patch #360 (patch by
    Vladimir A. Pavlov).
    -use XDrawString rather than XDrawString16 for text when the latter is not
    needed.
    -improve performance for initializing/reusing graphic objects in the SIXEL
    feature.
    -improve error-checking for resize.
    -fix errata in manual page (Debian #988221).
    -extended list of environment variables to purge on startup, i.e., in case a
    user starts xterm from another terminal emulator.
    -add comment in cursor.c to explain why autowrap (DECAWM) does not apply to
    data saved/restored with save/restore cursor-operations (report by Thomas
    Wolff).
    -add special case in generating the combining-character table in wcwidth.c,
    for Hangul Jamo Extended-B (report by Luis Javier Merino).
    -simplify/improve portability of trap commands in shell-scripts.
    -update configure options
     --disable-rectangles,
     --disable-tcap-fkeys and
     --disable-tcap-query
     to account for changed default settings.
    -rather than ignore empty parameter for setting title, use that to reset it
    to “xterm” for scripting.
    -check for out-of-bounds condition while drawing sixels, and quit that
    operation (report by Nick Black).
    -add fallback definition for PROJECTROOT so that a suitable default location
    for luit will be compiled-in on build-servers.
    -implement DEC status-line controls DECSASD/DECSSDT:
        decode controls, set state
        implement DECRQSS responses
        implement indicator-style status-line
        add configure option --enable-status-line
        add resource indicatorFormat
        implement host-writable status-line, able to handle video-attributes and
        simple left/right cursor movement. This disallows all of the DEC/xterm
        private modes such as switching to/from the alternate screen.
        move the status-line if the window is resized.
        Note: the associated screen-resizing does not work for the special case
        of TrueType fonts with double-buffering (see note in patch #349).
    -modify configure-script fixup for -Werror options to exclude fixup for
     -Werror=format, e.g., -Werror=format-security.
    -amend change from patch #370; DEC 070's pseudo-code for DECCOLM incorrectly
    suggests that it enables DECLRMM as a side-effect.
    -fix some memory leaks seen using esctest and asan2 (patch by Luis Javier
    Merino).
