Extract Curses differences and adaptation sections, and
move them to doc/CURSES.md. Reference this new document
in README.md. We now have sufficiently few sections that
we can dispense with the ToC. Do so.
We used to set all four quadrant bits if a full block
came through pool_direct_load(). Since users of this
function are going to be explicitly setting the quadrant
bits themselves immediately after this call, there's no
point (except for manual writes of full blocks, but those
ought be uncommon enough not to tip the scales the other
way -- this optimization was directed at blitters).
About a 5% speedup in notcurses-demo. Originates in #1316.
Eliminate NCDIRECT_OPTION_NO_READLINE (it was only introduced in
Notcurses 2.1.6). Add a new function, ncdirect_readline(). Upon
first call to this function, initialize libreadline. Destroy
libreadline in ncdirect_stop() iff we initialized it. Add
hilodirect guessing game PoC from #1325. Rename
notcurses_directmode.3 to notcurses_direct.3. Closes#1326.
Implement channels_set_fg_palindex() and channels_set_bg_palindex()
in terms of channel_set_palindex(). Add missing entries to
notcurses_channels.3 man page. Use uint32_t in place of unsigned
when dealing with channels in notcurses.h.
