Make dsa_allocate interface more like MemoryContextAlloc.
A new function dsa_allocate_extended now takes flags which indicate
that huge allocations should be permitted, that out-of-memory
conditions should not throw an error, and/or that the returned memory
should be zero-filled, just like MemoryContextAllocateExtended.
Commit 9acb85597f1223ac26a5b19a9345849c43d0ff54, which added
dsa_allocate0, was broken because it failed to account for the
possibility that dsa_allocate() might return InvalidDsaPointer.
This fixes that problem along the way.
Thomas Munro, with some comment changes by me.
