Update xterm to version 377 / rev 134 via SR 1040169
https://build.opensuse.org/request/show/1040169
by user msmeissn + dimstar_suse
- update to 377:
* add control sequences for reporting the current state of the
modified keys options (XTQMODKEYS) and allowed/disallowed
operations (XTQALLOWED), (prompted by discussion with Bram
Moolenaar).
* amend modifyOtherKeys case 2 to distinguish the escape character
with modifiers, e.g., shift-escape, from a plain escape character
(suggested by Bram Moolenaar).
* improve parsing and error-recovery in the case where a list of X11
bitmap fonts is given in the -fn and related options.
* change default for xftTrackMemUsage to false, because libXft has
does not handle certain fonts. (forwarded request 1039839 from dirkmueller)
