simplehash: Additional tweaks to make specifying an allocator work.

Browse Source 
Even if we don't emit definitions for SH_ALLOCATE and SH_FREE, we
still need prototypes.  The user can't define them before including
simplehash.h because SH_TYPE isn't available yet.

For the allocator to be able to access private_data, it needs to
become an argument to SH_CREATE.  Previously we relied on callers
to set that after returning from SH_CREATE, but SH_CREATE calls
SH_ALLOCATE before returning.
