LockedPool: fix explosion for illegal-sized alloc

Check for unreasonable alloc size in LockedPool rather than lancing through new
Arenas until we improbably find one worthy of the quixotic request or the system
can support no more Arenas.

Do not shadow variable, use deprecated MAP_ANON if MAP_ANONYMOUS is not defined.

support: Add LockedPool

Add a pool for locked memory chunks, replacing LockedPageManager.

This is something I've been wanting to do for a long time. The current
approach of locking objects where they happen to be on the stack or heap
in-place causes a lot of mlock/munlock system call overhead, slowing
down any handling of keys.

Also locked memory is a limited resource on many operating systems (and
using a lot of it bogs down the system), so the previous approach of
locking every page that may contain any key information (but also other
information) is wasteful.
