[PATCH 1/2] Split ufs.mod into ufs1.mod and ufs2.mod

[Vladimir 'phcoder' Serbinenko]

ufs1 and ufs2 mainly differ by some structure definitions. Putting
them into the same module and checking on runtime creates continuous
if ( ... == UFS1) { ... }
By using preprocessor it's possible to avoid most of such ifs
Additionally user needs only one FS in core so we save some space
core.img with ufs.mod: 23793
core.img with ufs1.mod: 23078
core.img with ufs2.mod: 23322
