repair: specify unit for ui.progress in rebuildfncache()

repair: use 'rebuilding' progress topic in rebuildfncache()

largefiles: use revisions as a ui.progress unit Using plural form is consistent with other progress units, and "1 out of 5 revisions" sounds more correct. Also, tests don't show this, but if you have 'speed' item in progress.format config, it shows e.g. '100 revisions/sec', which also seems better.

largefiles: specify unit for ui.progress when operating on files Also make it available for translation. It could already be translated, because it's used as a unit in archival.py and subrepo.py, for example.

templater: make label() just fail if ui object isn't available Silent failure hides bugs and makes it harder to track down the issue. It's worse than raising exception. In future patches, I plan to sort out template functions that require 'ui', 'ctx', 'fctx', etc. so that incompatible functions are excluded and the doc can say in which context these functions are usable. @templatefunc('label', requires=('ui',)) def label(context, mapping, args): ...

convert: fix "stdlib import follows local import" problem in transport Before this patch, import-checker reports error below for importing subversion python binding libraries. stdlib import "svn.*" follows local import: mercurial

convert: fix relative import of stdlib module in subversion Before this patch, import-checker reports "relative import of stdlib module" error for importing Pool and SubversionException from svn.core in subversion.py. To fix this relative import of stdlib module, this patch adds prefix 'svn.core.' to Pool and SubversionException in source. These 'svn.core.' relative accessing shouldn't cause performance impact, because there are much more code paths accessing to 'svn.core.' relative properties. BTW, in transport.py, this error is avoided by assignment below. SubversionException = svn.core.SubversionException But this can't be used in subversion.py case, because: - such assignment in indented code block causes "don't use camelcase in identifiers" error of check-code.py - but it should be placed in indented block, because svn is None at failure of importing subversion python binding libraries (= examination of 'svn' is needed)

convert: make subversion import transport locally Introducing "absolute_import" feature in previous patch caused failure of importing local module "transport".

dockerdeb: add Ubuntu Trusty One problem reported by lintian is "bad-distribution-in-changes-file unstable" in changelog, but the current changelog for the official package in Ubuntu also uses that distribution name (unstable), because they import from Debian. This certainly doesn't stop the build process.
