vim-patch:8.2.0559: clearing a struct is verbose
Problem: Clearing a struct is verbose.
Solution: Define and use CLEAR_FIELD() and CLEAR_POINTER().

Problem: Command line history code is spread out.
Solution: Put the code in a new file. (Yegappan Lakshmanan, closesvim/vim#4779)
Also graduate the +cmdline_hist feature.

** 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.
The size of long varies depending on architecture, in contrast to the
MAXLNUM constant which sets the maximum allowable number of lines to
2^32-1. This discrepancy may lead to hard to detect bugs, for example
https://github.com/neovim/neovim/issues/18454. Setting linenr_T to a
fix maximum size of 2^32-1 will prevent this type of errors in the
future.
Also change the variables `amount` and `amount_after` to be linenr_T
since they're referring to "the line number difference" between two
texts.
Uncrustify version 0.75 assumes the macro inside the enum is an enum
element, and thus adds a comma after it. This breaks neovim and makes it
impossible to build it.
Add space around arithmetic operators '+' and '-'.
Remove space between back-to-back parentheses, i.e. ')(' vs. ') ('.
Remove space between '((' or '))' of control statements.
Add space between ')' and '{' of control statements.
Remove space between function name and '(' on function declaration.
Collapse empty blocks between '{' and '}'.
Remove newline at the end of the file.
Remove newline between 'enum' and '{'.
Remove newline between '}' and ')' in a function invocation.
Remove newline between '}' and 'while' of 'do' statement.
`:verbose` didn't work properly with lua configs (For example:
options or keymaps are set from lua, just say that they were set
from lua, doesn't say where they were set at.
This fixes that issue. Now `:verbose` will provide filename and line no
when option/keymap is set from lua.
Changes:
- compiles lua/vim/keymap.lua as vim/keymap.lua
- When souring a lua file current_sctx.sc_sid is set to SID_LUA
- Moved finding scripts SID out of `do_source()` to `get_current_script_id()`.
So it can be reused for lua files.
- Added new function `nlua_get_sctx` that extracts current lua scripts
name and line no with debug library. And creates a sctx for it.
NOTE: This function ignores C functions and blacklist which
currently contains only vim/_meta.lua so vim.o/opt wrappers aren't
targeted.
- Added function `nlua_set_sctx` that changes provided sctx to current
lua scripts sctx if a lua file is being executed.
- Added tests in tests/functional/lua/verbose_spec.lua
- add primary support for additional types (:autocmd, :function, :syntax) to lua verbose
Note: These can't yet be directly set from lua but once that's possible
:verbose should work for them hopefully :D
- add :verbose support for nvim_exec & nvim_command within lua
Currently auto commands/commands/functions ... can only be defined
by nvim_exec/nvim_command this adds support for them. Means if those
Are defined within lua with vim.cmd/nvim_exec :verbose will show their
location . Though note it'll show the line no on which nvim_exec call was made.
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
As Strings and Blobs are encoded as msgpack BINs, the current ShaDa
implementation will restore global Blob variables as Strings (or msgpack
special dicts if they contain NULs).
Encode an additional element with Blob globals to differentiate them
from Strings so that we can restore them with the correct type.
Adjust variables_spec.lua's autotest() to also check for proper type.
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.
If set the number of history saves is 0, assertions fail when inserting an entry on exit.
Dont insert an entry when the number of saves is 0 fixes the issue.
fixes#11497
Since 8b8ecf4, the shada module loads files in the jumplist to properly
clear duplicates. This can trigger some autocommands, which in turn
saves and restores search and substitute patterns, freeing the previous
strings in "spats" which are held in "wms" as well (heap-use-after-free).
To avoid this, initialize the jumplist in "wms" before search patterns.
- Always load files when cleaning up jumplist.
- For Shada: avoids writing duplicate entries, which happens when you read
from a shada file with duplicate entries (merging the jumplist while
writing sometimes produces duplicate entries, bug?) and then write right
away (i.e.: without any `:jumps`, `getjumplist()`, or any jump movement,
that is: nothing that calls `cleanup_jumplist` with `loadfiles == true`).
- For Context: avoids non-idempotent behavior for the same reason (i.e.:
first call to `shada_encode_jumps` does not remove duplicate entries).
- Do not set pcmark when dumping jumplist for Context.
- Retrieving current Context shouldn't add an entry to the jumplist
(which will be removed by a subsequent `cleanup_jumplist` anyway, i.e.:
tail entry matching current position), just act like `getjumplist` for
instance.
Problem: Terminal buffers are stored in the viminfo file while they can't
be useful.
Solution: Skip terminal buffers for file marks and buffer list

- Check shada_pack_xx() result, abort on failure.
- Use xcalloc() to zero-initialize `wms`, fixes below ASAN failure.
ASAN failure (running vim_spec.lua in a loop):
../src/nvim/shada.c:1773:13: runtime error: load of value 224, which is not a valid value for type 'bool'
SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior ../src/nvim/shada.c:1773:13
Adding an explicit check just before the ASAN failed line:
case kSDItemRegister: {
if (*((int *)(void *)&entry.data.reg.is_unnamed) != 1
&& *((int *)(void *)&entry.data.reg.is_unnamed) != 0) {
abort();
(gdb) p entry.data.reg
+p entry.data.reg
$5 = {name = 49 '1', type = kMTLineWise, contents = 0x60200000c250, is_unnamed = true, contents_size = 1, width = 0, additional_data = 0x0}
(gdb) p *((uint8_t *)(void *)&entry.data.reg.is_unnamed)
+p *((uint8_t *)(void *)&entry.data.reg.is_unnamed)
$7 = 2049
Nvim notes:
- Nvim does not support "-u DEFAULTS", that change is omitted.
- Also add 'shadafile' as an alias to 'viminfofile'.
- Deprecate 'viminfofile'.
Problem: Not easy to start Vim cleanly without changing the viminfo file.
Not possible to know whether the -i command line flag was used.
Solution: Add the --clean command line argument. Add the 'viminfofile'
option. Add "-u DEFAULTS".

Note about shada.c:
- shada_read_next_item_start was intentionally shadowing `unpacked` and
`i` because many of the macros (e.g. ADDITIONAL_KEY) implicitly
depended on those variable names.
- Macros were changed to parameterize `unpacked` (but not `i`). Macros
like CLEAR_GA_AND_ERROR_OUT do control-flow (goto), so any other
approach is messy.
