discovery: drop the visiblebranchmap function

clfilter: drop extra filtering in wireprotocol The repository used by wireprotocol is already filtered. We no longer need to call special functions.

clfilter: filter "unserved" on all wireprotocol command calls This ensures that unserved changesets are not exposed through the wire protocol.

clfilter: drop extra filtering in localpeer The repository used by localpeer is already filtered. We no longer need to call a special function.

clfilter: make localpeer use a repo with "unserved" filter This changeset installs a broad filter on most repos used for serving. This removes the need to use the `visiblehead`/`visiblebranchmap` functions, and ensures that changesets we should not serve are in fact never served. We do not use filtering on hgweb yet, as there is still a number of issues to solve there.

performance: speedup computation of extinct revisions In their current state, revset calls can be very costly, as we test predicates on the entire repository. This change drops revset calls in favor of direct testing of the phase of changesets.

performance: speedup computation of mutable revisions In their current state, revset calls can be very costly, as we test predicates on the entire repository. The "mutable" filter is used during branch cache loading operation. We need to make it fast. This change drops revset calls in favor of direct testing of the phase of a changeset.

performance: speedup computation of unserved revisions In their current state, revset calls can be very costly, as we test predicates on the entire repository. The "unserved" filter is used in multiple applications, and in particular in some branch cache loading operations. We need to make it fast. This change drops revset calls in favor of direct testing of the phase of a changeset.

performance: speedup computation of hidden revisions In their current state, revset calls can be very costlys, as we test predicates on the entire repository. The hidden filter is very widely used, and needs to be very fast. This change drops revset calls in favor of direct revision manipulation. Performance test on my Mercurial checkout - 19857 total changesets, - 1584 obsolete changesets, - 13310 obsolescence markers. Before: ! hidden ! wall 0.077553 After this changes: ! hidden ! wall 0.011230 Performance test on a Mozilla central checkout: - 117293 total changesets, - 1 obsolete changeset, - 1 obsolescence marker.

performance: speedup computation of obsolete revisions In their current state, revset calls can be very costly as we test predicates on the entire repository. As obsolete computation is used by the "hidden" filter, it needs to be very fast. This changet drops the revset call in favor of direct testing of the phase of a changeset.

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

hgweb, spartan: link from manifest title to changeset page

hgweb, spartan: add "URL breadcrumbs" This change adds a "URL breadcrumb" to the "title" of the pages on the spartan template. By title I mean the first line that is shown right below the page selection row, which shows the name of the page that is being viewed, along with some additional information. In doing so it standarizes those "titles" which now follow the pattern: URL breadcumb / page details
