long is 32-bits even on 64-bit windows which makes the type suboptimal

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.

Problem:
When the CurSearch highlight group is set, and a search is active and
you are listening to the remote UI "win_viewport" events, then typing is
very unresponsive, because "win_viewport" is not sent as soon as the
character is typed. On the other hand if you refresh the screen on
"flush", the screen will scroll with a delay since "win_viewport" comes
too late. I estimate this delay be up to one second, but it varies.
Solution:
Call validate_cursor() before drawing the screen, just like other modes.
No tests have been added because only the intermediate state is wrong.

Special keys are negative integers, so sending them to terminal leads to
strange behavior.

Removes the `getoption_T` struct and also introduces the `OptVal` struct
to unify the methods of getting/setting different option value types.
This is the first of many PRs to reduce code duplication in the Vim
option code as well as to make options easier to maintain. It also
increases the flexibility and extensibility of options. Which opens the
door for things like Array and Dictionary options.

libvterm v0.3 supports reflow of terminal buffer when Nvim is resized
Since v0.3 is now a required dependency, enable it by default to find
(and fix) possible issues.
Note: Neovim's scrollback buffer does not support reflow (yet), so lines
vanishing into the buffer due to a too small window will be restored
without reflow.

This reduces the total number of khash_t instantiations from 22 to 8.
Make the khash internal functions take the size of values as a runtime
parameter. This is abstracted with typesafe Map containers which
are still specialized for both key, value type.
Introduce `Set(key)` type for when there is no value.
Refactor shada.c to use Map/Set instead of khash directly.
This requires `map_ref` operation to be more flexible.
Return pointers to both key and value, plus an indicator for new_item.
As a bonus, `map_key` is now redundant.
Instead of Map(cstr_t, FileMarks), use a pointer map as the FileMarks struct is
humongous.
Make `event_strings` actually work like an intern pool instead of wtf it
was doing before.

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.

Problem:
On Windows, pasting multiple lines on a terminal buffer cause all the
lines to appear on the same line, i.e., the line breaks are lost.
Cause:
Windows shells expect "\r\n" as line break but "terminal_paste" function
uses "\n".
Solution:
Use "\r\n" as line break for pasting in terminal buffer on Windows.
Note:
Although this issue was reported with powershell set as 'shell', it
occurs in cmd too.
Fixes #14621

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.

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.

This was used in the past with assumption that curwin/curbuf
is "special" but this has not been true since basically forever
at this point.
Reduce NOT_VALID/CLEAR panic in options.lua . These should not
be set if an effect of the option is causing something
which by itself invokes redraw_later().

Problem: The screen.c file is much too big.
Solution: Split it in three parts. (Yegappan Lakshmanan, closes vim/vim#4943)
https://github.com/vim/vim/commit/7528d1f6b5422750eb778dfb550cfd0b0e540964
This is an approximation vim-patch 8.1.2057. Applying the patch directly
isn't feasible since our version of screen.c has diverged too much,
however we still introduce drawscreen.c and drawline.c:
- screen.c is now a much smaller file used for low level screen functions
- drawline.c contains everything needed for win_line()
- drawscreen.c contains everything needed for update_screen()

- Remove autocmd.h from fileio.h
- Remove normal.h from main.h
- Move bufinfo_T from undo_defs.h to undo.c

Solution:
Change terminal_destroy and terminal_close to set caller storage to NULL,
similar to XFREE_CLEAR. This aligns with the pattern found already in:

The size of long varies depending on architecture, in contrast to the
MAXLNUM constant which sets the maximum allowable number of lines to
2^32-1. This discrepancy may lead to hard to detect bugs, for example
https://github.com/neovim/neovim/issues/18454. Setting linenr_T to a
fix maximum size of 2^32-1 will prevent this type of errors in the
future.
Also change the variables `amount` and `amount_after` to be linenr_T
since they're referring to "the line number difference" between two
texts.

* on_scrollback_option_changed renamed to adjust_scrollback. The
function name did not correspond to what it was doing. It is
called unconditionally in every refresh of the terminal
unrelated if the scrollback option was changed.
* new on_scrollback_option_changed function, which calls
refresh_terminal, which then calls adjust_scrollback
* terminal_check_size is not the appropriate function to call when the
option is changed since it only conditionally adjusts the scrollback.
Use the new on_scrollback_option_changed

At the moment of comparison, the pointer save_curwin can be invalid (as
suggested by the comment) because it has been free'd. Worst, the new
curwin could have been re-allocated to that same pointer, altering the
execution flow unpredictably.
While there are many other potential similar cases to fix in the
codebase, the presented scenario is not hypothetical and does happen in
practice (while spawning new windows from fzf for instance).
There are numerous other instances of curwin comparisons in the
codebase, and they may need further investigation.
