kernel - Change the discrete mplock into mp_token
* Use a lwkt_token for the mp_lock. This consolidates our longer-term
spinnable locks (the mplock and tokens) into just tokens, making it
easier to solve performance issues.
* Some refactoring of the token code was needed to guarantee the ordering
when acquiring and releasing the mp_token vs other tokens.
* The thread switch code, lwkt_switch(), is simplified by this change
though not necessarily faster.
* Remove td_mpcount, mp_lock, and other related fields.
* Remove assertions related to td_mpcount and friends, generally folding
them into similar assertions for tokens.
