Mark Johnston 9978bd996b Add malloc_domainset(9) and _domainset variants to other allocator KPIs.
Remove malloc_domain(9) and most other _domain KPIs added in r327900.
The new functions allow the caller to specify a general NUMA domain
selection policy, rather than specifically requesting an allocation from
a specific domain.  The latter policy tends to interact poorly with
M_WAITOK, resulting in situations where a caller is blocked indefinitely
because the specified domain is depleted.  Most existing consumers of
the _domain KPIs are converted to instead use a DOMAINSET_PREF() policy,
in which we fall back to other domains to satisfy the allocation
request.

This change also defines a set of DOMAINSET_FIXED() policies, which
only permit allocations from the specified domain.
