fuzz: add hg to sys.path when constructing mpatch corpus
Differential Revision: https://phab.mercurial-scm.org/D10777
==========================================================
Test file dedicated to checking side-data related behavior
==========================================================
Check data can be written/read from sidedata

Check upgrade behavior
======================
Right now, sidedata has not upgrade support
Check that we can upgrade to sidedata
