iterator such that future calls to `next()` were after the nth element.
This commit fixes that.

Added the `AMchangeHashes` struct.
Added the `AMchange` and `AMchanges` structs.
Tied the lifetime of an `AMobjId` struct to the `AMresult` struct that
it's returned through so that it can be used to reach equivalent objects
within multiple `AMdoc` structs.
Removed the `AMfreeObjId()` function.
Renamed `AMallocDoc()` to `AMalloc()`.
Added the `AMcommit()` function.
Added the `AMgetChangeHash()` function.
