rHG071f97d03acb: manifest: rename manifestlog._treeinmem to ._treemanifests
Summary

Not sure what "inmem" was supposed to indicate. This object is an
interface to manifest data on disk as well as "in memory" (assuming
that's what "inmem" means).

We used to have a way to do tree-in-memory but flat-on-disk, IIRC.

_treeinmem was used for indicating that the treemanifest type should be used in memory and this variable (_treeondisk) was used for indicating that treemanifest revlogs should be used. The only reason this distinction was useful was so you could set manually force _treeinmem = True in the code and run the test suite to make sure that the treemanifest type worked.
