Watch unaligned lumps and per-region free heap 2021-08-24 19:12:30 +02:00

Support multiple zones in Z_Malloc and add user stack leftover 
lumpinfo is now allocated in Z_Malloc because it's needed for some
larger WADs.

More heap is needed to compensate and to support larger WADs fully, so
the unused part of the user stack is added as a second zone.

This makes at least the start of the DOOM Ultimate WAD playable.

Initialize memory allocator with 422 kB system stack 
Instead of ProgrammerNerd's in-user-stack 256 kB stack which works both
quickly hits its size limit when playing.
