KNF

I started to KNF this file but quickly ended up figuring out I was not
courageous enough for such ugliness. So I only KNF'ed the first 300
lines.

I'll come back later.

Don't spam if mount fails due to invalid file system.

Initialise the "fork" local variable in hfslib_get_file_extents().
This variable was not actually used uninitialised, but some compilers

Inspired by PR 41255 from Kurt Lidl.
