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: Not easy to get mark en cursor posotion by character count.
Solution: Add functions that use character index. (Yegappan Lakshmanan,
closesvim/vim#7648)

Problem: Giving error messages is not flexible.
Solution: Add semsg(). Change argument from "char_u *" to "char *", also
for msg() and get rid of most MSG macros. (Ozaki Kiichi, closes
vim/vim#3302) Also make emsg() accept a "char *" argument. Get rid of
an enormous number of type casts.

* refactor: format with uncrustify
* fixup(dundar): fix functions comments
* fixup(dundar): remove space between variable and ++/--
* fixup(dundar): better workaround for macro attributes
This is done to be able to better use uncrustify rules for macros
* fixup(justin): make preprocessors follow neovim style guide
Problem: Items in a list given to :const can still be modified.
Solution: Work like ":lockvar! name" but don't lock referenced items.
Make locking a blob work.

Problem: Negative index doesn't work for Blob.
Solution: Make it work, add a test. (closesvim/vim#3856)

Leave tv_blob_get()'s return type untouched.
Problem: Code for Blob not sufficiently tested.
Solution: Add more tests. Fix uncovered crash. Add test_null_blob().

eval0 and ex_echo's emsg-specific changes have already been ported.
These tests uncover another crash that was fixed in v8.1.0738.
Problem: Cannot handle binary data.
Solution: Add the Blob type. (Yasuhiro Matsumoto, closesvim/vim#3638)
6e5ea8d2a9
Nvim-specific Blob conversions are implemented in future commits.
Refactor write_blob() to use a FileDescriptor, as f_writefile() was
refactored to use one (does not apply to read_blob()).
Use var_check_lock() in f_add() for Blobs from v8.1.0897.
Add a modeline to test_blob.vim and fix some doc typos.
Include if_perl.txt's VIM::Blob() documentation. Interestingly, this
function already worked before this port, as it just returns a Blob
string literal, not an actual Blob object.
N/A patches for version.c:
vim-patch:8.1.0741: viminfo with Blob is not tested
Problem: Viminfo with Blob is not tested.
Solution: Extend the viminfo test. Fix reading a blob. Fixed storing a
special variable value.

vim-patch:8.1.1022: may use NULL pointer when out of memory
Problem: May use NULL pointer when out of memory. (Coverity)
Solution: Check for blob_alloc() returning NULL.

Problem: Obvious mistakes are accepted as valid expressions.
Solution: Be more strict about parsing numbers. (Yasuhiro Matsumoto,
closesvim/vim#3981)
16e9b85113
Update vim_str2nr_spec.lua to add more tests that use strict = true.
Problem: Code to handle callbacks is duplicated.
Solution: Add callback_T and functions to deal with it.
3a97bb3f0f
Port Vim's put_callback() as callback_put()
because Neovim's naming convention is {type}_{action},
not {action}_{type}.
Renaming put_callback type as PutCallback.

assert() is compiled out for release builds, but we don't want to
continue running in these impossible situations.
This also resolves the "implicit fallthrough" warnings for the asserts
in switch cases.
Problem: Comparing two NULL list fails.
Solution: Change the order of comparing two lists.

Problem: Build failure with normal features.

vim-patch:8.2.1198: terminal2 test sometimes hangs in the GUI on Travis
Problem: Terminal2 test sometimes hangs in the GUI on Travis.
Solution: Move test function to terminal3 to see if the problem moves too.
