revlog: use dedicated code for reading sidedata We are about to introduce a new, dedicated, file to store sidedata.

The reading is very simple right now and will need some improvement later to reuse some of the caching strategy we use for the data file. Differential Revision: https://phab.mercurial-scm.org/D10785
