every new segment, including a trailing backslash. Simplified . and .. logic.
Converted switch to if because there were few cases left.

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.

does truename("D:", CDS_MODE_SKIP_PHYSICAL), and this mode was changed
to no longer call QRemote_Fn (int2f/ax=1123).

IBM PCDOS technical reference says to call BLDBPB if there are no used
buffers, so we only do it then, instead of flushing the buffers.

was always preceeded by split_path(). The return code is now an error code,
DE_FILENOTFND, DE_PATHNOTFND, or SUCCESS, depending on the failure.

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 *".

(split_path()) which only uses it to find out if the path ends in a backslash
and the length of the directory part.

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:\.

to truename (newstuff.c), because TRUENAME should check these characters
before passing paths on to fatfs.c & fatdir.c.

* 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.

Simple country support is kept: COUNTRY=31 will look for country.sys but
if it does not exist, not complain and load the built-in info.

* merge unstable kernel optimizations
* enable seek for int2f/AX=1228
* -1 is a valid offset, so we need to process the return code seperately

r_si/r_di contents added as documented in PC-DOS Technical Update.
I also moved the CharReqHdr filling in to just before execrh, and
made the command table a static const so it is outside the SDA (OW places
it in CONST2).

stack usage. Always return DE_ACCESS when the device fails instead
of DE_DEVICE, as DE_DEVICE is only used for renames between devices that
are not the same.
