This introduces the following breaking changes:
- nvim_get_keymap now always returns a LuaRef object as "callback" for a
Lua mapping regardless of how it is called. The LuaRef object can be
called from Lua and Vim script, but is lost over RPC.
- maparg() now returns a Funcref instead of a ref number as "callback"
for a Lua mapping. The Funcref can be called from Lua and Vim script,
but is lost over RPC.
This may also make nvim_get_keymap faster, but make maparg() slower.
`!did_throw` doesn't exactly imply `!current_exception`, as `did_throw = false`
is sometimes used to defer exception handling for later (without forgetting the
exception). E.g: uncaught exception handling in `do_cmdline()` may be deferred
to a different call (e.g: when `try_level > 0`).
In #7881, `current_exception = NULL` in `do_cmdline()` is used as an analogue of
`did_throw = false`, but also causes the pending exception to be lost, which
also leaks as `discard_exception()` wasn't used.
It may be possible to fix this by saving/restoring `current_exception`, but
handling all of `did_throw`'s edge cases seems messier. Maybe not worth
diverging over.
This fix also uncovers a `man_spec.lua` bug on Windows: exceptions are thrown
due to Windows missing `man`, but they're lost; skip these tests if `man` isn't
executable.
Problem: The option.c file is too big.
Solution: Split off the code dealing with strings. (Yegappan Lakshmanan,

Cherry-pick set_string_option_direct_in_win() from patch 8.1.1405.
Cherry-pick shift_line() comment change from patch 8.1.2096.
Move 'clipboard' default parsing to didset_string_options().
Reorder option flags to put Nvim-only flags at the end.
problem: code for drawing statusline is arbitrarily spreadout between drawscreen.c, screen.c and buffer.c
solution: move it to a new file statusline.c
- rename archaic internal name "status match" to public name "wildmenu"
- showruler() does not show the ruler. it show anything which displays
info about the cursor. Rename it accordingy.
Problem: The screen.c file is much too big.
Solution: Split it in three parts. (Yegappan Lakshmanan, closesvim/vim#4943)

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()

Problem: Clearing a struct is verbose.
Solution: Define and use CLEAR_FIELD() and CLEAR_POINTER().

Problem: Support for user commands is spread out. No good reason to make
user commands optional.
Solution: Move user command support to usercmd.c. Always enable the
user_commands feature.

Reduce the amount of string allocations and length calculations.
With the following benchmark:
```lua
total = 0
for _ = 1, loops do
local start = now()
vim.api.nvim_cmd({cmd = 'let', args = {'a', '=', '1'}}, {})
total = total + (now() - start)
end
print('nvim_cmd', total / loops)
```
```

Problem: Vim9: bool option type is number.
Solution: Have get_option_value() return a different value for bool and
number options. (closesvim/vim#7583)

Cherry-pick ins_compl_len() -> get_compl_len() from patch 8.2.4001.
Revert a71c5e9eb9: ctrl_x_mode is no
longer a global variable, so l_ctrl_x_mode is no longer needed.
In case nvim A sends nvim_error_event to nvim B, it would
respond with another nvim_error_event due to unknown
request name. Fix this by adding dummy request handler for now.
** Refactor
Previously most functions used to "get" a mark returned a position,
changed the line number and sometimes changed even the current buffer.
Now functions return a {x}fmark_T making calling context aware whether
the mark is in another buffer without arcane casting. A new function is
provided for switching to the mark buffer and returning a flag style
Enum to convey what happen in the movement. If the cursor changed, line,
columns, if it changed buffer, etc.
The function to get named mark was split into multiple functions.
- mark_get() -> fmark_T
- mark_get_global() -> xfmark_T
- mark_get_local() -> fmark_T
- mark_get_motion() -> fmark_T
- mark_get_visual() -> fmark_T
Functions that manage the changelist and jumplist were also modified to
return mark types.
- get_jumplist -> fmark_T
- get_changelist -> fmark_T
The refactor is also seen mainly on normal.c, where all the mark
movement has been siphoned through one function nv_gomark, while the
other functions handle getting the mark and setting their movement
flags. To handle whether context marks should be left, etc.
** Mark View
While doing the refactor the concept of a mark view was also
implemented:
The view of a mark currently implemented as the number of lines between
the mark position on creation and the window topline. This allows for
moving not only back to the position of a mark but having the window
look similar to when the mark was defined. This is done by carrying and
extra element in the fmark_T struct, which can be extended later to also
restore horizontal shift.
*** User space features
1. There's a new option, jumpoptions+=view enables the mark view restoring
automatically when using the jumplist, changelist, alternate-file and
mark motions. <C-O> <C-I> g; g, <C-^> '[mark] `[mark]
** Limitations
- The view information is not saved in shada.
- Calls to get_mark should copy the value in the pointer since we are
using pos_to_mark() to wrap and provide a homogeneous interfaces. This
was also a limitation in the previous state of things.
