+ + improve description of BSD-style padding in curs_termcap.3x

+ + relax modification-time comparison in CF_LINK_FUNCS to allow it to
+ accept link() function with NFS filesystems which change the mtime
+ on the link target, e.g., several BSD systems.

+ Rajeev V Pillai).
+
+20210320
+ + improve parameter-checking in tput by forcing it to analyze any
+ extended string capability, e.g., as used in the Cs and Ms
+ capabilities of the tmux description (report by Brad Town,
+ cf: 20200531).

+ + if the build-time compiler accepts c11's _Noreturn keyword, use that

+ + improve tic warning when oc/op do not mention SGR 39/49 for xterm
+ compatible XT flag.
+ + revert change to lib_addch.c in waddch_literal() from 20210130, since
+ the followup fix in PutCharLR() actually corrects the problem while
+ this change causes too-early filling/wrapping (report by Johannes
+ Altmanninger).

+ + add scrt/securecrt and absolute -TD
+ + add nel to xterm-new, though supported since X11R5 -TD
+ + add/use xterm+nofkeys -TD
+ + move use of ecma+italics from xterm-basic to xterm+nofkeys -TD

+ wide-character, rather than a new part of a multibyte character.
+ + improve tracemunch's coverage of form/menu/panel libraries.
+ + improve tracemunch's checking/reporting the type for the first
+ parameter, e.g., "WINDOW*" rather than "#1".

+ + provide for wide-characters as background character in wbkgrnd
+ (report/testcase by Anton Vidovic)
+ + add name for Fedora's pcre2 to configure check for "--with-pcre2"
+ option, from xterm #363 -TD
+ + modify adjustment in PutCharLR to restore the cursor position before
+ writing to the lower-right corner, rather than decrementing the
+ cursor column, in case it was a double-width character (cf: 20210130).
+
20210130
+ correct an off-by-one in comparison in waddch_literal() which caused
scrolling when a double-cell character would not fit at the lower
+ re-enable "bel" in konsole-base (report by Nia Huang)
+ add linux-s entry (patch by Alexandre Montaron).
+ drop long-obsolete convert_configure.pl
- + add test/test_parm.c, for checking tparm changes.
+ + add test/test_tparm.c, for checking tparm changes.
+ improve parameter-checking for tparm, adding function _nc_tiparm() to
handle the most-used case, which accepts only numeric parameters
(report/testcase by "puppet-meteor").
