Fix `_resync_feedback` to flush after every write in trac-admin, so for slow
syncs you actually can see progress instead of `sys.stdout` buffering the
output.

Merged documentation changes from 2008-04-29

Workaround display glitch for progress bars in Safari (closes #7170)

Improve the version information for Wiki page reviews.

Closes #7168.

TicketQuery: refactor `expand_macro` to clean-up its code layout after recent changes

TicketQuery: take care of fine-grained TICKET_VIEW permission on tickets, for the formats other than ''table'' which already does it.

Closes #7105.

TicketQuery: ''format=count'' now re-uses some of the Query code to directly perform the count at the sql level (from #216).

This is much cheaper but has the disadvantage of by-passing the fine-grained permission checks.

Note however that the same can be said for #216, and there, it's not only the count but also the whole paging logic (use of `LIMIT` and `OFFSET`) that doesn't take the fine-grained permissions into account. So the problem has to be fixed there, if possible.

Note that the only adverse effect will be to show ticket counts higher than the number of tickets actually shown to the user.

TicketQuery: for ''format=table'' the query was executed needlessly twice...

Update documentation of the TicketQuery macro (''max'' and ''row'' parameters)

Fix the reversal of forbidden ticket changes, as hinted by ebray in #7169.
