Problem:
There is no indication of when cursor is "behind" an unfocused, floating window.
Solution:
Set underline cursor to indicate when an unfocused floatwin is over the active cursor.

This commit unifies the usage of range and full/delta requests as
recommended by the LSP spec and aligns neovim with the way other LSP
clients use these request types for semantic tokens.
When a server supports range requests, neovim will simultaneously send a
range request and a full/delta request when first opening a file, and
will continue to issue range requests until a full response is
processed. At that point, range requests cease and full (or delta)
requests are used going forward. The range request should allow servers
to return a result faster for quicker highlighting of the file while it
works on the potentially more expensive full result. If a server decides
the full result is too expensive, it can just error out that request,
and neovim will continue to use range requests.
This commit also fixes and cleans up some other things:
- gen_lsp: registrationMethod or registrationOptions imply dynamic
registration support
- move autocmd creation/deletion to on_attach/on_detach
- debounce requests due to server refresh notifications
- fix off by one issue in tokens_to_ranges() iteration
Problem: 0x08 is treated as Backspace instead of Ctrl-H on Windows.
Solution: Treat 0x7f as Backspace if VT input is enabled, so that 0x08
is treated as Ctrl-H.

Problem:
Temporary files from /tmp/ and /private/ paths clutter :oldfiles list.
Additionally, the documented Windows default (rA:,rB:) was never applied
due to a missing platform condition.
Solution:
Drop platform-specific shada differences and default to excluding
/tmp/ and /private/ paths.
Problem: The wildmenu is hidden behind the dialog window with "list" in 'wildmode'.
Global ('laststatus' set to 3) statusline is hidden behind the
pager window.
Solution: Check wildmenumode() to adjust the dialog position when necessary.
Ensure pager is positioned above the global statusline with 'laststus' set to 3.
problem: currently when empty string is set as prompt the prompt-mark
column doesn't update.
solution: ensure the column is reset to 0 when starting prompt buffer and
before creating a new prompt after prompt-callback.
Problem: Internal messages do not have an ID, which is unexpected and
undocumented.
Solution: Always assign a msg_id to msg_show events, simplifying
logic/expectations for UIs.
Problem: No empty msg_ruler event after leaving a window whose ruler
is not part of the statusline with 'rulerformat'.
Solution: Properly keep track of when a ruler event was emitted with
'rulerformat' to emit clear event.
Problem: Scheduled callbacks reference potentially outdated window
handles e.g. after switching tabpage.
Solution: Use ext.wins which stores the updated window handles.
Problem:
Using vim.defer_fn() just before Nvim exit leaks luv handles.
Solution:
Make vim.schedule() return an error message if scheduling failed.
Make vim.defer_fn() close timer if vim.schedule() failed.
Problem:
On Windows, writing to a pipe doesn't work if the pipe isn't connected
yet. This causes an RPC request to a session newly created by connect()
to hang, as it's waiting for a response to a request that never reaches
the server.
Solution:
Wait for uv.pipe_connect() callback to be called when using connect().
Problem:
Currently, : mark is set in start of prompt-line. But more relevant
location is where the user text starts.
Solution:
Store and update column info on ': just like the line info
Previously, adjust_start_col returned nil when completion items had
different start position from lsp textEdit range
This caused the completion to fall back to \k*$ which ignores the
non-keyword characters
Changes:
- adjust_start_col: now returns the minimum start postion among all
items instead of nil
- _lsp_to_complete_items - normalizes the items by adding the gap between
current and minimum start
Fixes: https://github.com/neovim/neovim/issues/37441
Problem: 'cursorline' and part of 'statusline' are missing after
:diffput to an empty buffer.
Solution: Make sure the cursor doesn't go beyond the last line after
:diffput (zeertzjq)

Problem: Unexpected behavior after PTY child process fails to chdir(),
as it then thinks it's the parent process.
Solution: Exit the child process instead of returning.
Problem: Heap UAF if a terminal buffer is deleted during TermRequest in
Normal mode.
Solution: Increment terminal refcount before triggering TermRequest, and
destroy the terminal if the buffer is closed during that.
Problem: Wrong terminal scrollback if BufFile* autocommand drains PTY
output but doesn't process the pending refresh.
Solution: Refresh scrollback before refreshing screen in terminal_open()
if scrollback has been allocated.
Problem:
The :intro fails to display in ui2 because wait_return(true) triggers a full
redraw. Furthermore statuslines are visible when using :intro
Solution:
Replace wait_return() with plain_vgetc(). This works with old and ui2 while also removing the unnecessary statusline and "press ENTER" prompt.
Updates tests to work with new behaviour.

Problem:
Two cases lsp.enable() won't work in the first FileType event
1. lsp.enable luals inside FileType or ftplugin/lua.lua, then:
```
nvim a.lua
```
2. lsp.enable luals inside FileType or ftplugin/lua.lua, then:
```
nvim -> :edit a.lua -> :mksession! | restart +qa! so Session.vim
```
Solution:
Currently `v:vim_did_enter` is used to detected two cases:
1. "maunally enabled" (lsp.enable() or `:lsp enable`)
2. "inside FileType event"
To detect 2. correctly we use did_filetype().
Problem:
Calling os_chdir() to change the child processes' CWD may cause some
unnecessary UI events to be buffered. These UI events don't go anywhere
as execvp() is called before flushing the UI buffer.
Solution:
Use uv_chdir() instead of os_chdir(). Also fix getting error string
incorrectly. Add test for the current behavior.
Problem: Terminal loses output if a BufFilePre or BufFilePost autocmd
polls for events.
Solution: Rename the buffer after allocating the terminal instance. Also
fix buffer getting wrong name if BufFilePre uses NameBuff.
Problem: There are still ways to run into textlock errors with
vim.ui_attach callbacks trying to display a UI event.
Solution: Disregard textlock again during vim.ui_attach() callbacks
(also when scheduled). Partially revert 3277dc3b; avoiding
to flush while textlock is set is still helpful.
* cache all tokens from various range requests for a given document
version
- all new token highlights are merged with previous highlights to
maintain order and the "marked" property
- this allows the tokens to stop flickering once they've loaded once
per document version
* abandon the processing coroutine if the request_id has changed instead
of relying only on the document version
- this will improve efficiency if a new range request is made while a
previous one was processing its result
* apply new highlights from processing coroutine directly to the current
result when the version hasn't changed
- this allows new highlights to be immediately drawable once they've
processed instead of waiting for the whole response to be processed
at once
* rpc layer was changed to provide the request ID back in success
callbacks, which is then provided as a request_id field on the handler
context to lsp handlers
Usually, terminal_close() calls refresh_terminal(), which allocates the
scrollback buffer, and term_may_alloc_scrollback() in terminal_open()
won't dereference the buffer. However, refresh_terminal() is not called
during Nvim exit, in which case a heap-use-after-free may happen if
TermOpen wipes buffer. Check for non-NULL buf_handle to avoid that.
Problem: When TermOpen polls for enough events to use the scrollback
buffer, scrollback is lost until the next terminal refresh.
Solution: Allocate the scrollback buffer when it's needed.
Problem: Fast context for msg_show event inhibits vim.ui_attach from
displaying a stream of messages from a single command.
Solution: Remove fast context from msg_show events emitted as a result
of explicit API/command calls. The fast context was originally
introduced to prevent issues with internal messages.
Problem: Esc on commandline executes command instead of abandoning it.
Solution: Save and restore KeyTyped when removing the popup menu.

No code change is needed in Nvim as Nvim doesn't call update_screen() to
redraw pum.
