clfilter: drop unnecessary explicit filtering on histedit Hidden changeset filtering is now done at repo level. The orphaned children computation will not include any (unless you add --hidden).

clfilter: drop unnecessary explicit filtering on rebase Hidden changeset filtering is now done at repo level. The rebaseset computation will not include any (unless you add --hidden).

clfilter: ensure that hidden filtering is working on all commands Now that hidden changeset are filtered for all commands, we test the behavior of `heads` and `summary` regarding hidden changeset.

clfilter: enforce hidden changeset globally The dispatch code now enables filtering of "hidden" changesets globally. The filter is installed before command and extension invocation. The `--hidden` switch is now global and disables this filtering for any command. Code in log dedicated to changeset exclusion is removed as this global filtering has the same effect.

record: use patch.diffopts to account for user diffopts This allows user defined diff options (e.g. showfunc) to be accounted for when using record. A test has been updated accordingly.

convert: fix most test-check-code-hg violations in cvsps code

tests: update hgweb tests to include breadcrumbs

subrepo: add subrepo property to SubrepoAbort exceptions This new property contains the path of the subrepo that generated the exception. This information can then be used by GUI tools such as TortoiseHg.

tests: update test-convert-cvs*.t The preceding commit caused their outputs to change.

cvsps: use commitids (when present) to detect changesets Simplify core logic by no longer attempting to work around missing class attributes. Instead always generate the attributes and ignore the cache if the attributes are missing
