Added LFS3_F_REGBMAP and LFS3_F_COMPACTMETA

Browse Source 
These are unlikely to make much progress, but that doesn't seem like a
great reason to disallow these flags in lfs3_format:

  LFS3_F_REGBMAP      0x00002000  Repopulate the gbmap
  LFS3_F_COMPACTMETA  0x00008000  Compact metadata logs

These are actually guaranteed to do _no_ work when formatting _without_
the gbmap, but with the gbmap it's less clear. Looking forward to the
planned ckfactory feature, these may be useful for cleaning up any rbyd
commits created as a part of building the initial gbmap.

---

Also tweaked the formatting for LFS3_F_* flags a bit, including making
all ifdefs explicit (mainly ifdef LFS3_RDONLY). Mixed ifdefs are a real
pain to read.

No code changes.
