Replace the old hash used to hold file names within a directory with

open hashing.

An interesting optimization is that the open hashing interface is more
fine-grained, hence we can compute the correct hash value at the start
of Dir_FindFile, and reuse it for each hash structure into which we look
(the effect is measurable on large directories along with objdir/VPATH).

Remove a few unnecessary Lst_Open/Lst_Close that serve no purpose except
obfuscating the code.

The interface to dir.h changes slightly, hence tedious includes changes...
