50b06261b6 Implementation of truncate(), ftruncate() and the F_FREESP fcntl().
Implemented by changing write_map to accept a WMAP_FREE flag. In that
case, it doesn't update the datablock (creating indirect zones as
necessary) pointer, but it frees the datablock if present. Also it
frees the single and double indirect blocks if unused.

This makes the implementation of truncate_inode() simpler.
truncate_inode() now accepts a truncation length which makes
implementing truncate() and ftruncate() simple.

This also allowed implementing the F_FREESP fcntl().

6a911b5284 Merge of minix-vmd symlink code.
. new_node() now returns inode of parent dir as argument that
	  has to be put_node()d again by the caller of new_node().
	  it can also return the name of the last component as last_dir()
	  did.
	. advance() takes a pointer to a pointer of an inode as the
	  parent now. This parent can change, in which case the old
	  one is put_node()d and a new one is put there.
	. eat_path() replaced by more flexible parse_path()
	. last_dir() replaced by call to parse_path().
	. do_slink(), do_readlink(), do_lstat() and slink_traverse() added.

Also added some truncate()/ftruncate()-introduction related changes.
(e.g. renamed truncate() to truncate_inode().)

74711a3b14 Check if kernel calls is allowed (from process' call mask) added. Not yet
enforced. If a call is denied, this will be kprinted. Please report any such
errors, so that I can adjust the mask before returning errors instead of
warnings.

Wrote CMOS driver. All CMOS code from FS has been removed. Currently the
driver only supports get time calls. Set time is left out as an exercise
for the book readers ... startup scripts were updated because the CMOS driver
is needed early on. (IS got same treatment.) Don't forget to run MAKEDEV cmos
in /dev/, otherwise the driver cannot be loaded.

e44e9ad261 small compile fixes; initial select() stubs; release.sh script doesn't
need /tmp any more since 16MB root device; increase to 3.0.5 to make new
CD with working FXP driver. (not tagged 3.0.5 yet as at driver bios-copy
workaround hasn't been done.)

functionality). Currently working on memory allocation (not yet finished).

322ec9ef8b Moved stime, time, times POSIX calls from FS to PM. Removed child time
accounting from kernel (now in PM).  Large amount of files in this commit
is due to system time problems during development.
