SWCODEC: Get rid of extra swap buffer and get back 512K of RAM or 100K if the players RAM is <= 1MB. Make any needed changes to things to stabilize and facilitate this including removing flattening out initialization. Comment some things heavily. Fix a few logfs I didn't want to see the compiler complaining about.
