Problem: when processing cycle such as
:for pat in [' \ze*', ' \zs*']
: try
: let l = matchlist('x x', pat)
: $put ='E888 NOT detected for ' . pat
: catch
: $put ='E888 detected for ' . pat
: endtry
:endfor
`:let l = …` throwing an error causes this error to be caught after
color_cmdline attempts to get callback for highlighting next line (the one with
`$put = 'E888 NOT…`). Saving/restoring state prevents this from happening.
Problem: When creating a bufref, then using :bwipe and :new it might get
the same memory and bufref_valid() returns true.
Solution: Add br_fnum to check the buffer number didn't change.

Also re-word some error messages:
- "Key does not exist: %s"
- "Invalid channel: %<PRIu64>"
- "Request array size must be 4 (request) or 3 (notification)"
- "String cannot contain newlines"

Fixes problem introduced by “api: Allow kObjectTypeNil to be zero without
breaking compatibility”: apparently there are clients which use metadata and
there are which aren’t. For the first that commit would not be needed, for the
second that commit misses this critical piece.
During testing found the following bugs:
1. msgpack-gen.lua script is completely unprepared for Float values either in
return type or in arguments. Specifically:
1. At the time of writing relevant code FLOAT_OBJ did not exist as well as
FLOATING_OBJ, but it would be used by msgpack-gen.lua should return type
be Float. I added FLOATING_OBJ macros later because did not know that
msgpack-gen.lua uses these _OBJ macros, otherwise it would be FLOAT_OBJ.
2. msgpack-gen.lua should use .data.floating in place of .data.float. But it
did not expect that .data subattribute may have name different from
lowercased type name.
2. vim_replace_termcodes returned its argument as-is if it receives an empty
string (as well as _vim_id*() functions did). But if something in returned
argument lives in an allocated memory such action will cause double free:
once when freeing arguments, then when freeing return value. It did not cause
problems yet because msgpack bindings return empty string as {NULL, 0} and
nothing was actually allocated.
3. New code in msgpack-gen.lua popped arguments in reversed order, making lua
bindings’ signatures be different from API ones.
Reasonings:
1. It is not used for anything, but scope dictionaries currenly. So there is no
need to generalize and split it into dict_set_var (which will contain some
scope-dictionary-specific checks) and dict_set_value (which will work for any
dictionary).
2. Check for key size is no longer valid for non-scope dictionaries: you *can*
use empty keys there. In scope dictionaries also, but you actually are not
supposed to store there anything, but variables.
Note that actually one may still do
let b:[''] = 1
and “bypass” check for variable name. It won’t change what `echo b:` will show,
but it may affect code which iterates over scope dictionary keys and sets them
to something (if there is such code).
v7.4.2024 changed a few function signatures of functions that we use in
Neovim-specific code, e.g. the API.
Due to that the commit for 7.4.2024 doesn't build on its own, only together with
this commit.
Also fixed dumping of partials by encode_vim_to_object and added code which is
able to work with partials and dictionaries to test/unit/eval/helpers.lua
(mostly copied from #5119, except for partials handling).
