use ui instead of repo.ui when the former is in scope

cmdutils: Take over glob expansion duties from util

match: fix _patsplit breakage with drive letters

statichttprepo: handle remote not supporting Range headers - If remote does not support Range header, 200 is answered instead of 206. The HTTPRangeHandler left these responses unchanged, so the data has to be sliced by the receiver. - httprangereader file pointer was not updated.

convert: better feedback when filtering out empty revisions Original patch by Herbert Griebel <herbertg@gmx.at>

inotify: server: use a common 'pollable' interface for server & repowatcher Mainly for documentation purposes: it easily explains the role of handle_event and handle_timeout, and why both server & repowatcher implement those methods.

inotify: process all inotify events in one batch When several inotify events happen, we don't have to process each event separately, calling everytime repowatcher.read_events() to fetch events from the underlying watcher: it is sufficient to call once read_events, to fetch all the events from the watcher.

inotify: rename handle_event to handle_pollevent to avoid confusion event here refers to poll events, and are different from events read in server.read_events for example, where those events are inotify events.

inotify: handle_event: do not use event and fd parameters. event is particularly confusing given the context (is it an inotify event? a polling event?) and is never used. Remove it. fd has very little use, and it gives the false impression that event handling depends on fd. It's wrong: the same behavior is triggered, for all events.

inotify: use a decorator instead of dispatching calls
