Problem: buffer text with composing chars are converted from UTF-8
to an array of up to seven UTF-32 values and then converted back
to UTF-8 strings.
Solution: Convert buffer text directly to UTF-8 based schar_T values.
The limit of the text size is now in schar_T bytes, which is currently
31+1 but easily could be raised as it no longer multiplies the size
of the entire screen grid when not used, the full size is only required
for temporary scratch buffers.
Also does some general cleanup to win_line text handling, which was
unnecessarily complicated due to multibyte rendering being an "opt-in"
feature long ago. Nowadays, a char is just a char, regardless if it consists
of one ASCII byte or multiple bytes.
Problem: [security]: FPE in adjust_plines_for_skipcol
Solution: don't divide by zero, return zero
Prevent a floating point exception when calculating w_skipcol (which can
happen with a small window when the number option is set and cpo+=n).

We already have an extensive suite of static analysis tools we use,
which causes a fair bit of redundancy as we get duplicate warnings. PVS
is also prone to give false warnings which creates a lot of work to
identify and disable.
long is 32 bits on windows, while it is 64 bits on other architectures.
This makes the type suboptimal for a codebase meant to be
cross-platform. Replace it with more appropriate integer types.

- option_defs.h is for option-related types
- option_vars.h corresponds to Vim's option.h
- option_defs.h and option_vars.h don't include each other
Most of the messy things when changing a non-current buffer is
not about the buffer, it is about windows. In particular, it is about
`curwin`.
When editing a non-current buffer which is displayed in some other
window in the current tabpage, one such window will be "borrowed" as the
curwin. But this means if two or more non-current windows displayed the buffers,
one of them will be treated differenty. this is not desirable.
In particular, with nvim_buf_set_text, cursor _column_ position was only
corrected for one single window. Two new tests are added: the test
with just one non-current window passes, but the one with two didn't.
Two corresponding such tests were also added for nvim_buf_set_lines.
This already worked correctly on master, but make sure this is
well-tested for future refactors.
Also, nvim_create_buf no longer invokes autocmds just because you happened
to use `scratch=true`. No option value was changed, therefore OptionSet
must not be fired.
ml_get_buf() takes a third parameters to indicate whether the
caller wants to mutate the memline data in place. However
the vast majority of the call sites is using this function
just to specify a buffer but without any mutation. This makes
it harder to grep for the places which actually perform mutation.
Solution: Remove the bool param from ml_get_buf(). it now works
like ml_get() except for a non-current buffer. Add a new
ml_get_buf_mut() function for the mutating use-case, which can
be grepped along with the other ml_replace() etc functions which
can modify the memline.
Problem: Temporarily changing current window in a script causes
CursorMoved to be triggerd.
Solution: Don't trigger CursorMoved if neither curwin nor cursor
changed between two checks.
Problem: Bad redrawing with spell checking, using "C" and "$" in 'cpo'.
Solution: Do not redraw the next line when "$" is in 'cpo'. (closesvim/vim#11285)

Problem: With spell checking, deleting a full stop at the end of a line
does not update SpellCap at the start of the next line.
Solution: Update the next line when characters have been deleted. Also when
using undo.

libnvim couldn't be easily used in C++ due to the use of reserved keywords.
Additionally, add explicit casts to *alloc function calls used in inline
functions, as C++ doesn't allow implicit casts from void pointers.

Jackson)

drawscreen.c vs screen.c makes absolutely no sense.
The screen exists only to draw upon it, therefore helper functions
are distributed randomly between screen.c and the file that
does the redrawing. In addition screen.c does a lot of drawing on the
screen.
It made more sense for vim/vim as our grid.c is their screen.c
Not sure if we want to dump all the code for option chars into
optionstr.c, so keep these in a optionchar.c for now.
Problem: Reproducing memory access errors can be difficult.
Solution: When testing, copy each line to allocated memory, so that valgrind
can detect accessing memory before and/or after it. Fix uncovered
problems.

Since test_override() is N/A, enable ml_get_alloc_lines when ASAN is
enabled instead, so it also applies to functional tests.
Use xstrdup() to copy the line as ml_line_len looks hard to port.
Squash the test changes from patch 9.0.0016.

Allow Include What You Use to remove unnecessary includes and only
include what is necessary. This helps with reducing compilation times
and makes it easier to visualise which dependencies are actually
required.
Work on https://github.com/neovim/neovim/issues/549, but doesn't close
it since this only works fully for .c files and not headers.
Problem: Assert_fails() setting emsg_silent changes normal execution.

Cherry-pick no_wait_return from patch 9.0.0846.

This is a refactor extracted from vim-patch 9.0.0067: cannot show virtual text
The logic for inline virtual text is going to be different in nvim than
text property based text in vim, but this refactor is still useful,
as calculation of displayed linesize is going to be stateful in a
similar way.
