See users group request for iterating notes: https://groups.google.com/g/dynamorio-users/c/OOLkCNS24dA/m/aXMQkI77BAAJ?utm_medium=email&utm_source=footer

Xref complexities discussed there: whether the section headers are themselves mapped in via some loaded segment and whether the target section is mapped in or whether you have to go to disk.

There are other use cases for reading notes, in particular NT_GNU_BUILD_ID for recording while tracing, so adding a new API would be useful to multiple tools.

Xref rseq_process_module() which deals with some of the above.
