This makes parsing for build IDs in the markup filter slightly more
permissive, in line with fromHex.
It also removes the distinction between missing build ID and empty build
ID; empty build IDs aren't a useful concept, since their purpose is to
uniquely identify a binary. This removes a layer of indirection wherever
build IDs are obtained.

This creates a library for fetching debug info by build ID, whether
locally or remotely via debuginfod. The functionality was refactored
out of existing code in the Symboliize library. Existing utilities
were refactored to use this library.
