BACKPORT: removal of music slots
Relevant commits cherry-picked. Basically everything except the internal music track name switches.
See merge request !43
This fixes how removing certain flags (such as FF_EXISTS) from FOFs can cause HOMs on walls bordering their target sectors. Also fixes how the force-FOF-to-vanish linedef special can leave behind the FOF's shadow
Use whatever names you want for your music. So long as you prefix the lumps with O_ or D_, it doesn't matter anymore.
DISCLAIMER: Linedef type 413 (change music) and Lua scripting is not tested.
(cherry picked from commit 025ca413a2a01a8ec7c104748c2f510e350aa457)
# Conflicts:
# src/p_user.c
Compiling errors fixed in this commit:
* Various cases of mixed declaration and statement code
* Implicit declaration of slope functions (read: you forgot to put "include "p_slopes.h" in MORE than a few places)
* an odd case of a bad fixed_t to float typecase, cause by using P_GetZAt directly inside FIXED_TO_FLOAT
* a few minor cases of bad unsigned-signed comparisons
* no prototypes for some of the new slope functions. For goodness sake Red, this is basic stuff!

(It's that infamous intangible West/South linedefs bug, which was really a blockmap-related bug all along. AND IT WAS SO SIMPLE TO FIX!)
