- Add ncurses patch 20181229
+ improve man/curs_mouse.3x with regard to xterm
+ modify tracemunch to accept filename parameters in addition to use
as a pipe/filter.
+ minor optimization to reduce calls to _nc_reserve_pairs (prompted by
discussion with Bryan Christ).
+ add test/pair_content.c and test/color_content.c
+ modify infocmp to omit filtering of "OTxx" names which are used for
obsolete capabilities, when the output is sorted by long-names.
Doing this helps when making a table of the short/long capability
names.

- Add ncurses patch 20181215
+ several fixes for gcc8 strict compiler warnings.
+ fix a typo in comments (Aaron Gyes).
+ add nsterm-build309 to replace nsterm-256color, assigning the latter
as an alias of nsterm, to make mouse work with nsterm-256color -TD
+ base gnome-256color entry on "gnome", not "vte", for consistency -TD
+ updates for configure macros from work on tin and xterm:
+ CF_GNU_SOURCE, allow for Cygwin's newlib when checking for the
_DEFAULT_SOURCE symbol.
+ CF_VA_COPY, add fallback check if neither va_copy/__va_copy is
supported, to try copying the pointers for va_list, or as an array.
Also add another fallback check, for __builtin_va_copy(), which
could be used with AIX xlc in c89 mode.

- Add ncurses patch 20181208
+ modify wbkgd() and wbkgrnd() to improve compatibility with SVr4
curses, changing the way the window rendition is updated when the
background character is modified (report by Valery Ushakov).
