d525a5f7b5 [fs][fat][test] pass in the path to the test dir so files can be included correctly 
Due to the way INCBIN works, the full path relative to the root of the
assembler instance must be used, so pass in the full path as a define.

def9bea065 [fs][fat] general fs structural improvements 
Move more of the driver into a proper object oriented model.
Start to build the structure to track open file/dirs so as to
allow multiple open instances share the same underlying object.

to make sure there's at least one file that crosses a FAT sector.

variable.

Redo the entry parsing code to make a single pass across the long file
names to handle crossing sector boundaries.

d829ad24ef [fs][fat] fix up the mount and read logic in fat32

successfully reading a single file in the root directory that spans a
few 512 byte clusters.

c7bef34590 [lib][fs] fix path parsing bug 
If two mount points had similar names but one was longer, the path
matching logic would be triggered on the shorter name.

ie, /foo and /foo2 were illegal, since /foo2 path matching would match
against /foo. Tighten the logic a bit to match against the matching
element of the passed in path.

Note: heirarchial path matching still works, so /foo/bar/baz will match
against a mount point at /foo/bar. Debatable if heirarchial mount points
should work at the moment with this simple logic, but it's there for
now.

helper routines to feed into the PCI bus manager in the future.
