Problem:
`'scrollbind'` does not work properly if the window being scrolled
automatically contains any filler/virtual lines (except for diff filler
lines).
This is because when the scrollbind check is done, the logic only
considers changes to topline which are represented as line numbers.
Solution:
Write the logic for determine the scroll amount to take into account
filler/virtual lines.
Fixes#29751
Problem:
Variables are often assigned multiple places in common patterns.
Solution:
Replace these common patterns with different patterns that reduce the
number of assignments.
Use `MAX` and `MIN`:
```c
if (x < y) {
x = y;
}
// -->
x = MAX(x, y);
```
```c
if (x > y) {
x = y;
}
// -->
x = MIN(x, y);
```
Use ternary:
```c
int a;
if (cond) {
a = b;
} els {
a = c;
}
// -->
int a = cond ? b : c;
```
Problem: Printed line no longer overwrites colon when pressing Enter in
Ex mode (after 9.1.0573).
Solution: Restore the behavior of pressing Enter in Ex mode.

Problem: silent! causes following try/catch to not work
(Malcolm Rowe)
Solution: consider emsg_silent in handle_did_throw() and do not abort
evaluation flow for :silent! (LemonBoy)
The silent! flag causes the evaluation not to be aborted in case of
uncaught exceptions, adjust handle_did_throw to take this detail into
account.
Fixes the long-standing todo.txt item:
```
Problem that a previous silent ":throw" causes a following try/catch not
to work. (ZyX, 2013 Sep 28) With examples: (Malcolm Rowe, 2015 Dec 24)

The latter was mostly relevant with the past char_u madness.
NOTE: STRCAT also functioned as a counterfeit "NOLINT" for clint
apparently. But NOLINT-ing every usecase is just the same as disabling
the check entirely.
It's a function to perform operations in their own sealed context,
similar to pythons `with`. This helps ease operations where you need to
perform an operation in a specific context, and then restore the
context.
Marked as private for now as it's not ready for public use. The current
plan is to start using this internally so we can discover and fix any
problems. Once this is ready to be exposed it will be renamed to
`vim.with`.
Usage:
```lua
local ret = vim._with({context = val}, function()
return "hello"
end)
```
, where `context` is any combination of:
- `buf`
- `emsg_silent`
- `hide`
- `horizontal`
- `keepalt`
- `keepjumps`
- `keepmarks`
- `keeppatterns`
- `lockmarks`
- `noautocmd`
- `options`
- `sandbox`
- `silent`
- `unsilent`
- `win`
(except for `win` and `buf` which can't be used at the same time). This
list will most likely be expanded in the future.

Problem: too many strlen() calls in search.c
Solution: refactor code and remove more strlen() calls,

Problem: POSIX function name in exarg struct causes issues
on OpenVMS
Solution: Rename getline member in exarg struct to ea_getline,
remove isinf() workaround for VMS
There are compilers that do not treat well POSIX functions - like
getline - usage in the structs.
Older VMS compilers could digest this... but the newer OpenVMS compilers
( like VSI C x86-64 X7.4-843 (GEM 50XB9) ) cannot deal with these
structs. This could be limited to getline() that is defined via
getdelim() and might not affect all POSIX functions in general - but
avoiding POSIX function names usage in the structs is a "safe side"
practice without compromising the functionality or the code readability.
The previous OpenVMS X86 port used a workaround limiting the compiler
capabilities using __CRTL_VER_OVERRIDE=80400000
In order to make the OpenVMS port future proof, this pull request
proposes a possible solution.

Problem: Cannot use modifiers before :-Ntabmove.
Solution: Check backwards from the command instead of checking from the
start of the command line. Slightly adjust docs to make them

Problem: `set_string_option_direct()` contains a separate codepath specifically for setting string options. Not only is that unnecessary code duplication, but it's also limited to only string options.
Solution: Replace `set_string_option_direct()` with `set_option_direct()` which calls `set_option()` under the hood. This reduces code duplication and allows directly setting an option of any type.
A lot of functions in move.c only worked for curwin, alternatively
took a `wp` arg but still only work if that happens to be curwin.
Refactor those that are needed for update_topline(wp) to work
for any window.

and for return value of nlua_exec/nlua_call_ref, as this uses
the same family of functions.
NB: the handling of luaref:s is a bit of a mess.
add api_luarefs_free_XX functions as a stop-gap as refactoring
luarefs is a can of worms for another PR:s.
as a minor feature/bug-fix, nvim_buf_call and nvim_win_call now preserves
arbitrary return values.
Remove `export` pramgas from defs headers as it causes IWYU to believe
that the definitions from the defs headers comes from main header, which
is not what we really want.
Problem: Many places in the code use `findoption()` to access an option using its name, even if the option index is available. This is very slow because it requires looping through the options array over and over.
Solution: Use option index instead of name wherever possible. Also introduce an `OptIndex` enum which contains the index for every option as enum constants, this eliminates the need to pass static option names as strings.
FUNC_ATTR_* should only be used in .c files with generated headers.
Defining FUNC_ATTR_* as empty in headers causes misuses of them to be
silently ignored. Instead don't define them by default, and only define
them as empty after a .c file has included its generated header.
