2a05fbb949 Unroll the loop for calculating the 8.3 filename checksum. In testing
on my P3, microbenchmarks show the unrolled version is 78x faster.  In
actual use (recursive ls), this gives an average of 9% improvement in
system time and 2% improvement in wall time.

bddcdc5193 Use size_t or ssize_t wherever appropriate instead of casting from int *
to size_t *, which is incorrect because they may have different widths.
This caused some subtle forms of corruption, the mostly frequently
reported one being that the last character of a filename was sometimes
duplicated on amd64.

91f1c2b3cc Split the global timezone structure into two integer fields to
prevent the compiler from optimizing assignments into byte-copy
operations which might make access to the individual fields non-atomic.

Use the individual fields throughout, and don't bother locking them with
Giant: it is no longer needed.

e62d4b517b Fix winChkName() to match when the last slot contains nothing but the
terminating zero (it was treated as length missmatch). The mtools create
such slots if the name len is the product of 13 (max number of unicode
chars fitting in directory slot).

69a36f24fb Fixes for some bugs in the VFAT/FAT32 support:
- 'mv longnamedfile1 longnamedfile2' would cause longnamedfile2 to lose its
   long name.
 - Long names have trailing spaces/dots stripped for lookup as well as
   assignment.
 - A lockup when the mdsosfs was accessed from within the Linux emulator is fixed.
 - A bug whereby long filenames were recognised by Microsoft operating systems but
   not FreeBSD is fixed.

2b5b6623f6 Add initial support to map 0x4XX Unicode Cyrillic range names:
only win->unix part is implemented at this time with 256-byte
table defaulted to KOI8-R (will be loadable in future).
Since back mapping not supported yet, you'll get "No such file or directory"
on each Cyrillic name with 'ls -l', only 'echo *' work at this moment.
Teach current code to understand Unicode a bit.

952a6212d9 Update MSDOSFS code using NetBSD's msdosfs as a guide to support
FAT32 partitions.  Unfortunately, we looked around here at
Walnut Creek CDROM for any newer FAT32-supporting versions
of Win95 and we were unsuccessful; only the older stuff here.
So this is untested beyond simply making sure it compiles and
someone with access to an actual FAT32 fs will have
to let us know how well it actually works.

030e2e9ebb In sys/time.h, struct timespec is defined as:
/*
         * Structure defined by POSIX.4 to be like a timeval.
         */
        struct timespec {
                time_t  ts_sec;         /* seconds */
                long    ts_nsec;        /* and nanoseconds */
        };

        The correct names of the fields are tv_sec and tv_nsec.

63e4f22a2a Fix numerous timestamp bugs.
DE_UPDATE was confused with DE_MODIFIED in some places (they do have
confusing names).  Handle them exactly the same as IN_UPDATE and
IN_MODIFIED.  This fixes chmod() and chown() clobbering the mtime
and other bugs.

DE_MODIFIED was set but not used.

Parenthesize macro args.

DE_TIMES() now takes a timeval arg instead of a timespec arg.  It was
stupid to use a macro for speed and do unused conversions to prepare
for the macro.

Restore the left shifting of the DOS seconds count by 1.  It got
lost among the shifts for the bitfields, so DOS seconds counts
appeared to range from 0 to 29 seconds (step 1) instead of 0 to 58
seconds (step 2).

Actually use the passed-in mtime in deupdat() as documented so that
utimes() works.

Change `extern __inline's to `static inline's so that msdosfs_fat.o
can be linked when it is compiled without -O.

Remove faking of directory mtimes to always be the current time.  It's
more surprising for directory mtimes to change when you read the
directories than for them not to change when you write the directories.
This should be controlled by a mount-time option if at all.
