helixhorned b8ed142c6b Remove some #if 0 blocks that are probably of no interest any more. 
For reference, they are the following:
 - cache1d.c: suckcache()
 - build.c: compare_wall_coords()
 - make switch-invisible heuristic
 - Mapster32: old sprite search
 - Mapster32: manual z range
 - m32script: read/writearray, qgetsysstr
 - menus.c: savetemp()

// This module keeps track of a standard linear cacheing system.
// To use this module, here's all you need to do:
//
// Step 1: Allocate a nice BIG buffer, like from 1MB-4MB and
// Call initcache(int32_t cachestart, int32_t cachesize) where
//
// cachestart = (intptr_t)(pointer to start of BIG buffer)
// cachesize = length of BIG buffer
//
// Step 2: Call allocache(intptr_t *bufptr, int32_t bufsiz, char *lockptr)
// whenever you need to allocate a buffer, where:
//
// *bufptr = pointer to multi-byte pointer to buffer
// Confused? Using this method, cache2d can remove
// previously allocated things from the cache safely by
// setting the multi-byte pointer to 0.
// bufsiz = number of bytes to allocate
// *lockptr = pointer to locking char which tells whether
// the region can be removed or not. If *lockptr = 0 then
// the region is not locked else its locked.
//
// Step 3: If you need to remove everything from the cache, or every
// unlocked item from the cache, you can call uninitcache();
// Call uninitcache(0) to remove all unlocked items, or
// Call uninitcache(1) to remove everything.
// After calling uninitcache, it is still ok to call allocache
// without first calling initcache.
// Uncomment for easier allocache-allocated bound checking (e.g. with Valgrind)
