Adds an `smods` key to `nvim_create_user_command` Lua command callbacks,
which has command modifiers but in a structured format. This removes the
need to manually parse command modifiers. It also reduces friction in
using `nvim_cmd` inside a Lua command callback.
The docs for `nvim_buf_set_extmark` mention that you can create a new
extmark when passing in `id=0`, however if you do this you'll get an
error since the code checks that id is positive.
```
id is not a positive integer
```
This change re-words the sentence to make it clearer.
Adds the API function `nvim_cmd` which allows executing an Ex-command through a Dictionary which can have the same values as the return value of `nvim_parse_cmd()`. This makes it much easier to do things like passing arguments with a space to commands that otherwise may not allow it, or to make commands interpret certain characters literally when they otherwise would not.
It seems range and count can be used together in commands. This PR fixes
the behavior of `nvim_parse_cmd` for those cases by removing the mutual
exclusivity of "range" and "count". It also removes range line number
validation for `nvim_parse_cmd` as it's not its job to validate the
command.
Changes the `range` value in `nvim_parse_cmd` into an array to describe
range information more concisely. Also makes `range` and `count` be
mutually exclusive by making count `-1` when command takes a range
instead of a count. Additionally corrects the behavior of `count` for
built-in commands by making the default count `0`.
Adds range, count and reg to the return values of nvim_parse_cmd. Also makes
line1 and line2 be -1 if the command does not take a range. Also moves
nvim_parse_cmd to vimscript.c because it fits better there.
PROBLEM
------------------------------------------------------------------------
$NVIM_LISTEN_ADDRESS has conflicting purposes as both a parameter ("the
current process should listen on this address") and a descriptor ("the
current process is a child of this address").
This contradiction means the presence of NVIM_LISTEN_ADDRESS is
ambiguous, so child Nvim always tries to listen on its _parent's_
socket. This is the cause of lots of "Failed to start server" spam in
our test/CI logs:
WARN 2022-04-30… server_start:154: Failed to start server: address already in use: \\.\pipe\nvim-4480-0
WARN 2022-04-30… server_start:154: Failed to start server: address already in use: \\.\pipe\nvim-2168-0
SOLUTION
------------------------------------------------------------------------
1. Set $NVIM to the parent v:servername, *only* in child processes.
- Now the correct way to detect a "parent" Nvim is to check for $NVIM.
2. Do NOT set $NVIM_LISTEN_ADDRESS in child processes.
3. On startup if $NVIM_LISTEN_ADDRESS exists, unset it immediately after
server init.
4. Open a channel to parent automatically, expose it as v:parent.

Problem:
winpty is only needed for Windows 8.1. Removing it reduces our build and code
complexity.
Solution:
- Remove winpty.
- Require Windows 10.

* feat(api): `group` can be either string or int
This affects the following API functions:
- `vim.api.nvim_create_autocmd`
- `vim.api.nvim_get_autocmds`
- `vim.api.nvim_do_autocmd`
closes#17552
* refactor: add two maps for fast lookups
* fix: delete augroup info from id->name map
When in "stupid_legacy_mode", the value in name->id map would be updated
to `AUGROUP_DELETED`, but the entry would still remain in id->name. This
would create a problem in `augroup_name` function which would return the
name of the augroup instead of `--DELETED--`.
The id->name map is only used for fast loopup in `augroup_name` function
so there's no point in keeping the entry of deleted augroup in it.

This enables retrieving autocommands defined in the given buffers. Under
the hood this simply translates the buffer numbers into '<buffer=%d>'
patterns.
Works similar to ex <f-args>. It only splits the arguments if the
command has more than one posible argument. In cases were the command
can only have 1 argument opts.fargs = { opts.args }
nvim_buf_get_text is the mirror of nvim_buf_set_text. It differs from
nvim_buf_get_lines in that it allows retrieving only portions of lines.
While this can typically be done easily enough by API clients,
implementing this function provides symmetry between the get/set
text/lines APIs, and also provides a nice convenience that saves API
clients the work of having to slice the result of nvim_buf_get_lines
themselves.
