There are various allocations that can't be moved or shrunk.
Provide a global callback struct for this use case instead of
making each caller declare its own dummy struct.
Also fixed ROLO and x1000 installer code which incorrectly
used movable allocations.

This adds code sufficient to extract files to available storage given a
suitable root directory to extract to. It works on an already open zip
handle and also supports chain-loading a secondary callback in the event
that integration into the process is desired.

This provides rudimentary support for parsing the contents of a ZIP
file. For now this just supports uncompressed file entries but DEFLATE
support is planned. This also only implements a low level public API
so more work will be needed to make it usable by application code.
