Doom: use PU_CACHE in R_PrecacheLevel #373

This should prevent port to consume a lot of RAM and able to free it when necessary. RAM consumption after ~one minute of fast-forwarding Sunder maps by holding "Next Level":

Before: up to 1.1 GB
After: up to 560 MB

Needs extensive and long-time playtesting, but there now full demo sync for such cases.

Port was able to run for about 24 hours of playing tntf65200 (packed as DEMO1/2/3 along with tnt31.wad for inner demo loop playing) and no crushes are happening on nuts.wad. Probably, all previous silent crashes were caused by mixed usage of STATIC/CACHE in status bar code, which is now fixed entirely. PU_WELLDONE!
