commpage: randomize position of commpage

This patch introduces randomization of commpage position. From now on commpage
table contains offsets from begining to of the commpage to the particular
commpage entry. Similary addresses of symbols in ELF memory image "commpage"
are just offsets from the begining of the commpage.

This patch also updates KDL so that commpage entries are recognized and shown
correctly in stack trace. An update of Debugger is yet to be done.


# 02dd3236 30-Jul-2012 Alex Smith <alex@alex-smith.me.uk>

Better names for syscall/signal functions copied to the commpage.


# c0d28c01 30-Jul-2012 Alex Smith <alex@alex-smith.me.uk>

Implemented signals for x86_64.


# 370ab57d 23-Jul-2012 Alex Smith <alex@alex-smith.me.uk>

Initial userland support for x86_64.

Userland switch is implemented, as is basic system call support (using
SYSCALL/SYSRET). The system call handler is not yet complete: it doesn't
handle more than 6 arguments, and does not perform all the necessary kernel
entry/exit work (neither does the interrupt handler). However, this is
sufficient for runtime_loader to start and print some debug output.
