with fixes for adfs:
- factor out filename comparison, so we can be sure that adfs_compare()
(used for namei compare) and adfs_match() (used for lookup) have the
same behaviour.
- factor out filename lowering (which is not the same as tolower() which
will lower top-bit-set characters) to ensure that we have the same
behaviour when comparing filenames as when we hash them.
- factor out the object fixups, so we are applying all fixups to
directory objects in the same way, independent of the disk format.
- factor out the object name fixup (into the previously factored out
function) to ensure that filenames are appropriately translated -
for example, adfs allows '/' in filenames, which being the Unix path
separator, need to be translated to a different character, which is
normally '.' (DOS 8.3 filenames represent the . as a / on adfs, so
this is the expected reverse translation.)
- remove filename truncation; Al asked about this and apparently the
decision is to remove it. In any case, adfs's truncation was buggy,
so this rids us of that bug by removing the truncation feature.
- we now have only one location which adds the "filetype" suffix to the
filename, so there's no point that code being out of line.
- since we translate '/' into '.', an adfs filename of "/" or "//" would
end up being translated to "." and ".." which have special meanings.
In this case, change the first character to "^" to avoid these special
directory names being abused.
