push: fix bug in detection of remote obsolete support Current code check obsolete availability in local repo.

incoming/outgoing: handle --graph in core

log: support --graph without graphlog extension The glog command is preserved in the extension for backward compatibility.

graphlog: extract revset/support functions into cmdutil

graphlog: extract ascii drawing code into graphmod

patchbomb: rewrite getoutgoing() with revsets Another version could have returned a revset expression from getoutgoing(), but we do not know how many times it will be resolved, so better do it once explicitely.

patchbomb: support --outgoing and revsets With --outgoing, input revisions were passed to getoutgoing() before being resolved.

patchbomb: make --outgoing ignore secret changesets getoutgoing() is just rewritten almost like revset.outgoing(), a follow-up will make it use revsets after the tests are adjusted.

convert: make filemap renames consistently override revision renames When the source repository had a revision renaming "$new -> $old", but the filemap a "$old -> $new" rename, the converted revision could use either $new (deleting the file) or $old (keeping the file) when getting the file data, depending on the lexicographical order of those names. So the resulting revision would leave some files untouched (as expected), but delete others arbitrarely.
