update the CDS cluster. Call media_check explicitly in truename() as a central
first and only place in directory-using DOS calls (except DosFindNext)
to call it.

dir/filename separator to 0 can be avoided, and we don't need to calculate
its location in split_path(). Without the trick many more char * path
arguments in the kernel can become "const char *".

added was the need to check for "d:\" paths which return DE_NFILES.
Also, findfirst("d:\nonexist\*.*",D_VOLID) should fail even if it actually
searches in d:\.

* ignore 0x40 (D_DEVICE) in search attribute.
* if you specify D_VOLID + one or more of D_HIDDEN, D_SYSTEM, and D_DIR you
will get files *and* volume labels in the specified directory, not forced
to the root directory.
* VOLID searches must look at the search pattern name too, or do not match.

Because of the explicit dir_write() calls we only need them in situations
where SFTs where used, that is for open files but not for directories.

Its only purpose left was to flush buffers, which isn't necessary after
just open/read, so we can move that to dir_write().

dos_setfsize still needed to merge changes for SHARE so the call was replaced
by a new dos_merge_file_changes() call.

sector) fields to the fnode, to make fnodes more compatible with SFTs.
Use them to simplify dir_read() and dir_write().

field, simplifies remove_lfn_entries(), and avoids a bug if you delete
the first entry in the root directory on FAT32.

extend() now uses f_cluster instead of f_back, while map_cluster makes
sure it's not set to LONG_LAST_CLUSTER (but to the cluster before it)
when calling extend().
extend() and first_fat() now return the new cluster number or
LONG_LAST_CLUSTER, just like find_fat_free()
Hopefully I didn't break anything... Initial testing was successful.

save a few bytes too. Also changed the FcbParseFname return value:
returns offset portion of pointer (SI) instead of the number of bytes to
be added to SI.

and find_fat_free). This completely messed up rwblock. Removed these calls
(for directories they are already covered at a higher level) and added
a few sanity checks to dir_close and dir_write.

FAT16 partitions (just like FAT16 kernels do)
* added extra checks to make sure that invalid FAT entries are never
followed
* made put_console() public to be able to print a message in case of
FAT corruption
* some small optimizations and header cleanups (some suggested by Arkady)
