Tons of work on ncreel (#627, #749, #694)
Improve reel demo: get input wired up once more, avoid the FPS demo at bottom, print pointer and line count in each tablet, use new ncreel API. Improve notcurses-ncreel explorer: kill memory leaks (#694), draw tablets better, use new ncreel API. Fix bug in ncreel core where cruft could be left on the screen, via a very gross brute force algorithm. I'll likely come back and make this a bit less ghastly in the future #749. Remove weird one-off input system from ncreel, residue from outcurses. Make some of the normalizing changes speced out in #627
* ncreel: give each tablet an index, and print it #749
* reel: eliminate FIXME + param to insert_tabler() #749
* ncreel: label tablets with their adress to correlate against debugging logs #749
* more terminal environment variable notes
* TERMS.md: add Sakura, st
* ncreel: move legend out of reel proper
* ncreel_options: dump min/max_supported_rows/cols #627
* ncreel: remove weird one-off input layer #627
* ncreel: add ncreel_offer_input()
* reel demo: call demo_getc()
* reel demo: rig up input to demo main
* ncreel: drop ncreel_del_focused(), properly bind tablets
* reel demo: don't free up necessary plane
* ncreel: don't pull absolute locations of tablets
* ncreel: place tablets correctly in boundrel
* reel demo: add back support for left/right
* reel demo: restore thread movement
* ncreel: remove a great deal of complexity
* reel demo: stay out of FPS graph's way

* reel: brute force decruftification, how embarrassing #749
CELL_ALPHA_OPAQUE et al were defined as 0..3, meaning
CELL_ALPHA_SHIFT had to be used to compare them to their
channel representations. Instead, define them in said
representation outright, eliminating the need to shift while
retaining arithmetic properties, and zero initialization for
CELL_ALPHA_OPAQUE. Eliminate CELL_ALPHA_SHIFT #738.
The Plot unit tests were reaching directly into the objects,
which meant the implementations couldn't include anything
we didn't want public. This was annoying, so I've changed it.
This required adding ncdplot_sample() and ncuplot_sample(),
which we should have had anyway.
In order to properly determine the scaling of an ncvisual to
be rendered, ncvisual_geom() needs know the blitting method.
For this reason, it took an ncblitter_e argument. It also,
however, needs handle degradation, which means knowing whether
NCVISUAL_OPTIONS_NODEGRADE is in use. It thus really wants the
struct ncvisual_options. Pass and accept it. Closes#697, and
fixes the "yield" demo in ASCII mode (#696).
Very simple take at ncplane_puttext(), a new function for linebroken text. Also some very basic unit tests. I doubt this works very well yet, but it handles the simplest cases #682. Added nclog(), internal function for logging. #520
