bookmarks: Change references to "repo" by references to "self" (
issue1611)
Using "repo" instead of "self" inside bookmark_repo methods was causing a
circular reference and, thus, a memory leak. It has been detected because the
method bundlerepository.__del__ is never called, therefore leaving dangling
uncompressed bundles inside .hg subdirectory.
run-tests: use os.path.realpath() to find hg's setup.py.
Needed for running out-of-tree test suites without --with-hg/--local.
Make RPM spec in contrib more aligned with the one from Fedora
This is mostly syntactical changes which make the real differences more obvious
when looking at a diff.
contrib/mergetools.rc is now also installed and enabled by default.
