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.
We need support three distinct paths for destruction of
ncsubprocs: (1) external call to ncsubproc_destroy() while
the subprocess is running, (2) external call to
ncsubproc_destroy() after the subprocess has terminated, and
(3) internal call to ncsubproc_destroy() without any external
call. To do this properly, we always waitid() on the subprocess
in our ncsubproc thread, and do not cancel said thread. This
guarantees that the subprocess has been reaped if the thread
has exited. We throw a pidfd_send_signal() into the thread
prior to the waitid(), because this is safe with pidfds. The
thread reclaims no resources otherwise. ncsubproc_destroy(),
instead, reclaims them, after joining the ncsubproc thread.
It sends SIGKILL before the join, which is once again safe
thanks to pidfds. Resolves#552.

* ncplane_at_* and ncplane_at_cursor_*
We had notcurses_at_yx() expanding into three distinct parts of
the cell structure, and ncplane_at_yx() / ncplane_at_cursor()
writing directly to a cell. It was annoying to remember which
was which. The latter two now have a signature matching
notcurses_at_yx(), while the old functionality has been moved
to ncplane_at_yx_cell() and ncplane_at_cursor_yx(). #476
* packaging: s/libtinfo/Terminfo/g
* rust: add stddim_yx()
* rust: check for valid init in unit tests
* rust: serialize up tests
* constify notcurses_term_dim_yx()

Fill-type functions used to return 0 for success, and -1
on failure. They now return the number of cells written
on success, similarly to ncvisual_render(). Resolves#427.
Certain unit tests required UTF8 encoding on the output
terminal to work (#428). This includes anything which does
any kind of fill. Add enforce_utf8() checks to all such
tests that were missing them. Unit tests once again pass in
a pure ASCII environment.
Resolves#410. notcurses_at_yx() accepted a cell*, but the
gcluster of this cell was always set to 0. The EGC is instead
a heap-allocated copy, returned as the primary return value.
This is due to the absence of an egcpool to bind against.
Existing callers can be converted thus:
* instead of passing cell 'c', pass &(c)->attrword, &(c)->channels
* either initialize 'c' with CELL_TRIVIAL_INITIALIZER, or set its
gcluster field to 0 following the call
I've updated all calls from tests/demos, updated the docs, and
updated the C++ and Python wrappers.
Add ncplane_bound(3). This allows a new plane N to be created in the
*bound* state relative to another ncplane B. If B moves, N moves the
same amount. If N is moved, the coordinates are taken relative to B
as opposed to the standard plane. If B is destroyed, N is destroyed.
Each plane can have many planes bound to it, but can only be bound to
a single plane. Add ncplane_reparent(3). This allows a plane to be
detached from any plane to which it is bound, and optionally rebound
to a new plane. The standard plane cannot be reparented.
Documentation and unit tests have been added for both.
ncvisual_render() now returns the number of cells emitted
rather than just 0/-1. -1 is still returned on failure.
Rather than 0 for length meaning "all possible length", it
now means 0, and -1 means "all possible length". All demos,
tests, and PoCs have been updated. #422
