b8b8f537bd IPC privileges fixes
Kernel:
o Remove s_ipc_sendrec, instead using s_ipc_to for all send primitives
o Centralize s_ipc_to bit manipulation,
  - disallowing assignment of bits pointing to unused priv structs;
  - preventing send-to-self by not setting bit for own priv struct;
  - preserving send mask matrix symmetry in all cases
o Add IPC send mask checks to SENDA, which were missing entirely somehow
o Slightly improve IPC stats accounting for SENDA
o Remove SYSTEM from user processes' send mask
o Half-fix the dependency between boot image order and process numbers,
  - correcting the table order of the boot processes;
  - documenting the order requirement needed for proper send masks;
  - warning at boot time if the order is violated

RS:
o Add support in /etc/drivers.conf for servers that talk to user processes,
  - disallowing IPC to user processes if no "ipc" field is present
  - adding a special "USER" label to explicitly allow IPC to user processes
o Always apply IPC masks when specified; remove -i flag from service(8)
o Use kernel send mask symmetry to delay adding IPC permissions for labels
  that do not exist yet, adding them to that label's process upon creation
o Add VM to ipc permissions list for rtl8139 and fxp in drivers.conf

Left to future fixes:
o Removal of the table order vs process numbers dependency altogether,
  possibly using per-process send list structures as used for SYSTEM calls
o Proper assignment of send masks to boot processes;
  some of the assigned (~0) masks are much wider than necessary
o Proper assignment of IPC send masks for many more servers in drivers.conf
o Removal of the debugging warning about the now legitimate case where RS's
  add_forward_ipc cannot find the IPC destination's label yet

3cc092ff06 . new kernel call sysctl for generic unprivileged system operations;
now used for printing diagnostic messages through the kernel message
   buffer. this lets processes print diagnostics without sending messages
   to tty and log directly, simplifying the message protocol a lot and
   reducing difficulties with deadlocks and other situations in which
   diagnostics are blackholed (e.g. grants don't work). this makes
   DIAGNOSTICS(_S), ASYN_DIAGNOSTICS and DIAG_REPL obsolete, although tty
   and log still accept the codes for 'old' binaries. This also simplifies
   diagnostics in several servers and drivers - only tty needs its own
   kputc() now.
 . simplifications in vfs, and some effort to get the vnode references
   right (consistent) even during shutdown. m_mounted_on is now NULL
   for root filesystems (!) (the original and new root), a less awkward
   special case than 'm_mounted_on == m_root_node'. root now has exactly
   one reference, to root, if no files are open, just like all other
   filesystems. m_driver_e is unused.

2194bc0310 vfs/mount/rs/service changes:
. changed umount() and mount() to call 'service', so that it can include
   a custom label, so that umount() works again (RS slot gets freed now).
   merged umount() and mount() into one file to encode keep this label
   knowledge in one file.
 . removed obsolete RS_PID field and RS_RESCUE rescue command
 . added label to RS_START struct
 . vfs no longer does kill of fs process on unmount (which was failing
   due to RS_PID request not working)
 . don't assume that if error wasn't one of three errors, that no error
   occured in vfs/request.c
mfs changes:
 . added checks to copy statements to truncate copies at buffer sizes
   (left in debug code for now)
 . added checks for null-terminatedness, if less than NAME_MAX was copied
 . added checks for copy function success
is changes: 
 . dump rs label
drivers.conf changes:
 . added acl for mfs so that mfs can be started with 'service start',
   so that a custom label can be provided

f47aa04a30 . removed readclock command and cmos driver.
. replaced by a readclock 'driver' that runs once, a re-imported version
  of the minix 2.0.4 readclock command.
. this has also restored cmos writing.
. readclock wrapper script calls service command to run /bin/readclock.drv
  once.
