Problem: Session has wrong arglist with :tcd and :arglocal.
Solution: Also use absolute path for :argadd when there is tabpage-local
directory (zeertzjq).

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: Restore lastused_tabpage too early in do_arg_all() function it

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: Moving tabpages on :drop may cause an endless loop
Solution: Disallow moving tabpages on :drop when cleaning up the arglist
first
Moving tabpages during drop command may cause an endless loop
When executing a :tab drop command, Vim will close all windows not in
the argument list. This triggers various autocommands. If a user has
created an 'au Tabenter * :tabmove -' autocommand, this can cause Vim to
end up in an endless loop, when trying to iterate over all tabs (which
would trigger the tabmove autocommand, which will change the tpnext
pointer, etc).
So instead of blocking all autocommands before we actually try to edit
the given file, lets simply disallow to move tabpages around. Otherwise,
we may change the expected number of events triggered during a :drop
command, which users may rely on (there is actually a test, that expects
various TabLeave/TabEnter autocommands) and would therefore be a
backwards incompatible change.
Don't make this an error, as this could trigger several times during the
drop command, but silently ignore the :tabmove command in this case (and
it should in fact finally trigger successfully when loading the given
file in a new tab). So let's just be quiet here instead.

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.
We already have an extensive suite of static analysis tools we use,
which causes a fair bit of redundancy as we get duplicate warnings. PVS
is also prone to give false warnings which creates a lot of work to
identify and disable.

- option_defs.h is for option-related types
- option_vars.h corresponds to Vim's option.h

Problem: ":drop fname" may change the last used tab page.
Solution: Restore the last used tab page when :drop has changed it.

Problem:
The "force" flag of win_close() complicates the code and adds edge cases
where it is not clear what the correct behavior should be.
The "free_buf" flag of win_close() is passed on to float windows when
closing the last window of a tabpage, which doesn't make much sense.
Solution:
Remove the "force" flag and always close float windows as if :close! is
used when closing the last window of a tabpage, and set the "free_buf"
flag for a float window based on whether its buffer can be freed.
As 'hidden' is on by default, this change shouldn't affect many people.

Allow Include What You Use to remove unnecessary includes and only
include what is necessary. This helps with reducing compilation times
and makes it easier to visualise which dependencies are actually
required.

it since this only works fully for .c files and not headers.
