alloc: write out allocator definitions
Because the allocator functions for tree, blobs, etc are all very similar, we originally used a macro to avoid repeating ourselves. Since the prior commit, though, the heavy lifting is done by an inline helper function. The macro does still save us a few lines, but at some readability cost. It obfuscates the function definitions (and makes them hard to find via grep). Much worse, though, is the fact that it isn't used consistently for all allocators. Somebody coming later may be tempted to modify DEFINE_ALLOCATOR, but they would miss alloc_commit_node, which is treated specially. Let's just drop the macro and write everything out explicitly.
