This effectively reverts 1f824a0:
- LFS3_T_COMPACTMETA -> LFS3_T_COMPACT
- gc_compactmeta_thresh -> gc_compact_thresh
And friends.
After using LFS3_T_COMPACTMETA for a bit, I think it just adds noise
without much value. Especially when next to LFS3_T_LOOKAHEAD,
LFS3_GC_PREERASE, LFS3_M_SYNC, etc.
It's interesting that we already have some very distinct verbs for this
sort of thing based on data type (compact => metadata, garbage-collect
=> disk, compress => data).
