Require an NSID and CNS value to be passed to the nvme_identify()
function. This enables the caller to control what type of data is returned by
the NVMe controller.

This commit changes how reboot() handles REBOOT_HALT. Now instead of one
core being halted, all cores will be halted through an IPI to a halt
vector.

This commit removes handling of the PROC_INEXEC flag as md_td_kick() takes
care of the transfer to user mode in a cleaner way.

This commit introduces usage of swapgs to switch out the GS register
with the user GS register. An md_td_kick() function is also introduced
to start up user threads. The this_cpu() function uses the GS register
to read the current CPU structure using a new "self" field.

handler. This will be useful in the future for more complicated
operations that need to be done before the handler is ran.

Add stack initialization code for exec functions. This new code
initializes values on the stack, including argc, argv, and the
auxiliary vector.

This function will be useful for things like exec in order to setup
registers which are machine dependent.

Rename md_td_init() to md_fork() and change up what it does to keep
things as simple as possible.
