Renamed LFS3_T_COMPACT -> LFS3_T_COMPACTMETA (and gc_compactmeta_thresh)

Browse Source 
- LFS3_T_COMPACT -> LFS3_T_COMPACTMETA
- gc_compact_thresh -> gc_compactmeta_thresh

And friends:

  LFS3_M_COMPACTMETA   0x00000800  Compact metadata logs
  LFS3_GC_COMPACTMETA  0x00000800  Compact metadata logs
  LFS3_I_COMPACTMETA   0x00000800  Filesystem may have uncompacted metadata
  LFS3_T_COMPACTMETA   0x00000800  Compact metadata logs

---

This does two things:

1. Highlights that LFS3_T_COMPACTMETA only interacts with metadata logs,
   and has no effect on data blocks.

2. Better matches the verb+noun names used for other gc/traversal flags
   (REPOPGBMAP, CKMETA, etc).

It is a bit more of a mouthful, but I'm not sure that's entirely a bad
thing. These are pretty low-level flags.
