4fcf0eb13c Remove pm_Heads check in msdosfs_mountfs; this value isn't really used, 
FreeBSD and OpenBSD both removed this check years ago, and this makes an
8GB Memory Stick Pro Duo formatted with a PSP work.

f4d0142196 Implement auto-track repair on tracks marked damaged when searching for 
writable tracks on session opening. Note that this an optionally implemented
feature and thus no error will be generated if it fails; the drive will most
likely autorepair it.

not done correctly and could panic when requested to load a VAT descriptor
since the fileset was not yet fetched.

62c3c2d194 Check for a node being root on node creation so when the root node is disposed 
of when working deep into the directory tree it can reliably be reget and
marked correctly as the FS root.

Fixed pwd(1) lock panic and possible endless loop in other tools.

81723cc93e The great QUOTA purge of '08: get rid of those #ifdef QUOTA and 
#include "opt_quota.h" which do exactly nothing.  Speeds up kernel
compilation by 1.375*10^-20001 seconds.  But leave the most moxious
comment in msdosfs_vfsops untouched.

9b08c3c516 Two fold commit: 
1) Enhance write speed significantly on RMW media like CD-RW, DVD-RW but also
on the DVD+RW and all other ECC blocked media. Significant speedups of access
to the device for say compilation on the DVD. Streaming copy is also still at
maximum speed though vast amounts of directory copy work can show side effects
that appear it to slow down but are actually logical when you consider that
most small files are embedded into the descriptors itself.

2) explicit wait for the created RMW thread to spinup

df11d3f1f5 Allow for the exclusive selection of `direct' for rdonly mounts; its disabled

39beb124fd In case writing past EOF, fail if extending the file fails (most 
likely due to the file system being full).

Otherwise we'd fail in VOP_PUTPAGES(), which might not happen during
VOP_WRITE(), thus giving the caller the wrong impression that
writing was succesful.

f1481725b6 Remove logic to compute relative pathes to chroots. It breaks the 
default case of ptyfs mounted under /dev/pts as any chroot would get
/%d as slave names. This allows null mounts of ptyfs to work.
To allow pty allocation from within chroots, either no ptyfs must be
mounted or a null mount exist.

5e89a5a8f1 Fixup important bug in internal recorded data fixup. Although most unlikely 
it could result in theory result in descriptor trashing.

On the performance side, it would try to fixup *every* descriptor even if
it wasn't an internally allocated one. Performance loss wasn't that big but
every bit helps.
