Make some minor improvements in memory-context infrastructure. We lack a version of repalloc() that supports MCXT_ALLOC_NO_OOM semantics, so invent repalloc_extended() with the usual set of flags. repalloc_huge() becomes a legacy wrapper for that.
Also, fix dynahash.c so that it can support HASH_ENTER_NULL requests when using the default palloc-based allocator. The only reason it didn't do that already was the lack of the MCXT_ALLOC_NO_OOM option when that code was written, ages ago. While here, simplify a few overcomplicated tests in mcxt.c.
