Fix crash when `get_bvar_id` is used

`infallibleAppend` is crashing the server when amxmodx is compiled in non-debug mode. It happens because `growIfNeeded` is called inside `assert` which is a no-op in non-debug builds and no memory is allocated, so the data is written to invalid addresses and segfault happens.

Revert "Do not allow admins to change cvars with FCVAR_SPONLY flag when not in singleplayer via amx_cvar"

https://github.com/alliedmodders/amxmodx/pull/822/commits/adbc3e0c53f2e46179da32461afdf133556e9536

Behavior change. For now reverting it to give time and decide how it should be handled properly.

* Fix internal player's team id returning -1 in a specific but valid situation

* Use a local variable

* Fix spaces

* Adminslot: Trim spaces

* Adminslot: Use semicolon everywhere

* Adminslot: Use brackets everywhere

* Adminslot: Hook cvars change and make sure max visible players is set right away

* Adminslot: Rename g_sv_visiblemaxplayers

* Adminslot: Move free slot calculation in its own function

* Adminslot: Use create_cvar and define appropriate bounds

* Adminslot: Use get_playersnum_ex with flag for clarity

* Adminslot: Move all the logic inside setVisibleSlots

Looks like the commit should have been split for clarity.

The initial purpose is to avoid code duplication and regroup checks.
The logic is the same with a little improvement to handle situations where a cvar is changed on-the-fly and sv_visiblemaxplayers needs to be reset.

Ultimately, the logic is the following:

 - At player's connection:
 -- Do nothing if amx_reservation == 0 and sv_visiblemaxplayers <= 0. If sv_visiblemaxplayers is set, we reset it directly.
 -- Check if player needs to be kicked. If not, and amx_hideslots == 0, then do nothing.
 -- Otherwise we update sv_visiblemaxplayers

 - Others events:
 -- Do nothing if either amx_reservation == 0 or amx_hideslots == 0, and if sv_visiblemaxplayers <= 0. If sv_visiblemaxplayers is set, we reset it directly.
 -- Otherwise we update sv_visiblemaxplayers
