Also tweaked related flag comments a bit.
---
This adds another internal flag modifier ('a') to dbgflags.py to
indicate a flag is an alias for multiple other flags.
These still show up in -l/--list and name searches:
$ ./scripts/dbgflags.py -l +ck
LFS3_CK_MKCONSISTENT 0x00000100 Make the filesystem consistent
LFS3_CK_LOOKAHEAD 0x00000200 Repopulate lookahead buffer
LFS3_CK_COMPACT 0x00000800 Compact metadata logs
LFS3_CK_CKMETA 0x00001000 Check metadata checksums
LFS3_CK_CKDATA 0x00002000 Check metadata + data checksums
LFS3_CK_CK 0x00003000 Alias for all check work
LFS3_CK_GC 0x00003b00 Alias for all gc work
But are hidden from value searches, as they would be redundant and the
specific low-level flags are probably more useful:
$ ./scripts/dbgflags.py +ck 0x00003000
LFS3_CK_CKMETA 0x00001000 Check metadata checksums
LFS3_CK_CKDATA 0x00002000 Check metadata + data checksums
