2dd02cc560 mark pages whose refcount were >1 and drop to 1 and are 
read/write writable in the pagetable right away instead of waiting for
a pagefault. minor optimization.

some a sanity check of SLAB-allocated pointers.

vm gets its own _exit and __exit like PM, so the stock (library) panic works.

e0f3a5acf1 - enable ipc warnings by default 
- ipc checking code in kernel didn't properly catch the
   sendrec() to self case; added special case check
 - triggered by PM using stock panic() - needs its own _exit()

9647fbc94e moved type and constants for random data to include file; 
added consistency check in random; added source of randomness
internal to random using timing; only retrieve random bins that are full.

6a0e8e3b80 Added a separate keymap for escaped scancodes. This makes the code 
a little cleaner (escaped scancodes are less of a special case) and
lets us be completely flexible when assigning meaning to them.

Future: a tool and ioctl to load the escaped keymap.

80f5eea8b8 If serial debugging in the boot monitor / kernel is enabled, don't touch

c628f24bc2 moved stacktrace to sysctl, as vmctl is very privileged so can't 
be used outside VM. IS code cleanup. added stacktrace feature to IS.

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.
