kernel - Revamp subr_alist and get it ready for use
* Fix numerous bugs in the bighint code.
* Add API functions to allow static initialization.
* When shortcutting chunks we still should flesh out the parent's whole
array. This makes alist_free_info() easier to implement.
* Implement alist_free_info() which provides information on the largest
trailing chunk available (with some restrictions). This is used to
chop down a large preinitialization.
* Implement an allocate-after-block feature to alist_alloc()
* Implement natural alignment and boundary handling. Allocations can only
be in powers of 2 internally with odd-sized allocations allocating the
larger size and then piecemeal-freeing the trailing portion. This also
has the effect of ensuring that the boundary and alignment will always
be the nearest greater or equal power of 2 to the allocation request size.
