pull: add hgsubversion.filestoresize to control memory consumption
The configuration entry defines the size of the replay or stupid edited
file store, that is the maximum amount of edited files data in megabytes
which can be kept in memory before falling back to storing it in a
temporary directory. Default to 200 (megabytes), use -1 to disable.
