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().)

dd99ee67e0 Rename some #defines such as MAX_BLOCK_SIZE to _MAX_BLOCK_SIZE and such
so as to not pollute application namespace.

9664ba0c4f Started select() implementation.
Added interface to select() for pipes (also named pipes), and select()
stubs for regular files.

Added timer library in FS that select() is the first customer of.


This is unfinished, but committed anyway to get a new release out to
Al and testers.

c2cd510adf Removed debug dumps from the PM and FS servers. The dumps are now done by the
IS servers, which obtains a copy of the data through the getsysinfo() system
call. CTRL-F1 now is a special TTY key to shows function key mappings.

2f74381dcc Fixed 'ps' utility: now get process table addresses with getsysinfo() calls.
To be done: get copies of process tables instead of using /dev/(k)mem.
