Added the Drive Cache Descriptor Ring (DCDR) framework to manage the
caching of logical blocks for LBA-based storage mediums. This commit
implements core components including data structures for Drive Cache
Descriptors (DCDs) and Drive Cache Descriptor Rings (DCDRs). Other
implemented features include:
- DCD eviction policy based on least hit count
- DCD invalidation
- DCD lookups
- Support for logical block coalescing

This will be useful when fork() is implemented.

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.

Add macros that perform certain operations before invoking the actual
handler. This will be useful in the future for more complicated
operations that need to be done before the handler is ran.
