Graceful fallback among blitters #637
If we're in ASCII mode, no blitter except for NCBLIT_1x1 is going to
work. Whenever NCBLIT_DEFAULT is provided, select NCBLIT_1x1 if we're
in ASCII mode. Add NCVISUAL_OPTIONS_MAYDEGRADE and
NCPLOT_OPTIONS_MAYDEGRADE. Both serve to allow smooth degradation when a
blitter other than NCBLIT_DEFAULT has been provided. Closes #637.

Make calc_gradient_cell() static inline so our templated ncppplot
implementation can use it (ugh). When using NCBLIT_1x1 for plots in
ASCII mode, use space rather than full block, and invert colors.

Use NCBLIT_DEFAULT in the demo for the FPS plot.

Fully general ncvisual layer (#647)
This represents an essentially complete rewrite of ncvisual and associated code. It had two major goals:

Improve the ncvisual API based off lessons learned, pursuant to the upcoming API freeze. In particular, I wanted to:

decouple ncvisuals from ncplanes. It should be possible to render a ncvisual to multiple planes, with different scaling each time. It should be possible to create an ncvisual without a plane, etc.
normalize the various ways of constructing an ncvisual -- file, memory, plane, etc.
Support multiple blitters, from 7-bit ASCII to Sixel. This required writing the blitters in several cases, and they're not yet in their final implementations (but the API is fine)
I have not yet unified Plots and Visuals, and might not, given that the Plot code works fine. We could at this point implement Plots in terms of Visuals, though -- the blitter backend range has been unified. Sixel is not yet implemented, though it is listed.

There is a new POC tool, blitter. It renders its arguments using all possible blitter+scaling combinations. Another new POC, resize, displays its argument, then resizes it to the screen size and displays that, explicitly making use of ncvisual_resize() rather than a scaling parameter to ncvisual_render().

This also eliminates some memory leaks and bugs we were seeing in trunk, and brings in Sixel scaffolding.

The C++ wrapper will also need patching back up; I cut most of it down while wrestling with this crap, urk.

Closes #638, #562, and #622.

O(1) z-axis moves #623
Replace the singly-linked z-axis with a doubly-linked list,
and reimplement all z-axis moves as O(1) functions.
Eliminate ncplane_move_{above/below}_unsafe(), as there are no
longer unsafe moves.

f63325db60 Lots of ncvisual work
Unify ffmpeg/oiio/null implementations, where possible. This effectively
required placing all three in the same file, which meant they're all now
C++. Update FFmpeg implemenation to be C++-usable. Implement
ncvisual_rotate_cw() and ncvisual_rotate_ccw() #515. Move most of tetris
over to Visual from Plane #558. Add bgra_to_rgba(), necessary for
creating ncvisual from BGRA memory. Implement ncvisual_from_rgba()
and ncvisual_from_bgra() #557. Add unit tests on ncvisual rotation.
