repoview: invalidate 'visible' filtered revisions when bookmarks change
Context: the result of computehidden, used to compute the 'visible' revisions
is cached. Its output can change when:
1) new obsolete commits are created
2) new bookmarks are created or deleted
3) new tags are created or deleted
4) the parents of the working copy change
We currently correctly invalidate the cache only in the case 1).
This patch fixes the second case (bookmarks) by invalidating the cache once
a bookmark is added or removed.
ui: flush stderr after printing a non-chained exception for Windows
There were consistent test failures in test-bad-extension.t, because Windows
buffers stderr when redirected to a file (per the comment in ui.write_err()).
That resulted in failures like this:
--- c:/Users/Matt/Projects/hg/tests/test-bad-extension.t
+++ c:/Users/Matt/Projects/hg/tests/test-bad-extension.t.err

Traceback (most recent call last):
Exception: bit bucket overflow

+ Traceback (most recent call last):
+ ImportError: No module named badext2
show traceback for ImportError of hgext.name if debug is set
(note that --debug option isn't applied yet when loading extensions)
Instead of inserting another flush immediately after the print, to go along with
the one recently added prior to the print (see
3ff4b07412ad), funnel the output
through ui.write_err(). The flush prior to printing the traceback only mentions
that stdout needs to be flushed, and only stderr needs to be flushed after
printing the traceback. ui.write_err() does both for us without needing to
redocument the quirky Windows behavior. It will also clear any progress bar.
revset: use parentsets.min in _children
As stated in the comment, using the smartset 'min' will give more opportunity to
be smart. It give a small but significant boost to the performance. Most of the
time is still spend doing the actual computation but at least we can scrap some
performance when it makes sense.

Python is slow at attributes lookup. No, really, I mean -slow-. prefetching
these three methods give use a measurable performance boost.

hgweb: add some in-code documentation for 'web.view'
This documentation was mostly intended for the user helps. However given the
lack of request for such feature, we should keep it un-documented. We stick the
help text in the code as it could still be useful to fellow contributors.
bookmark: informs of failure to upgrade a bookmark
When we explicitly requested to update a bookmark but the bookmark location was
missing locally, we used to silently ignore the case. We now issue a message
about it to point that something wrong is going on.
By chance, we fixed all the cases where is case happened (for explicit pulling
only,
issue4700 is still open). But I think it is still valuable to have a
warning in place in case such issue is reintroduced.
This patch have been tested against
issue4689 test (but without
issue4689 fix).
It give the better but expected failure seen below:

fancyopts: allow all callable as default parameter value
The current fancyopts allows function as default parameter value
but not other callables.
By supporting other callables, we can have the benefits of e.g.,
custom __str__ method, which will be printed by 'hg help' as
the default value.
templater: evaluate arguments passed to diff() appropriately
Before this patch, diff() crashed by passing non-string expression because
it didn't evaluate arguments at all.
