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
the serial line in use for it (mostly so that input isn't eaten by tty).

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.

0579810535 don't ignore the fact that scancodes are escaped.
if not understood explicitly, print diagnostic and 
ignore scancode.

1d8aed840c . no more HZ, but use sys_hz() to get that value
. memory maps in physical memory (for /dev/mem) with new vm interface
 . pci complete_bars() seems to be buggy behaviour sometimes
 . startup script opens its own stdout, stderr and stdin so init doesn't
   have to do it
