changegroup: replace getsubset with makechangegroup
The current changegroup APIs are a bit of a mess. Currently you can use
getsubsetraw, getsubset, changegroupsubset, getlocalchangegroupraw,
getchangegroup, and getlocalchangroup to produce changegroups. This patch is the
beginning of a refactor to boil all of that away to just makechangegroup and
makestream.
The first step adds the new functions and replaces getsubset function with them.

rebase: remove unnecessary '.unfiltered()' calls
Now we have a clear centric place to control whether `rbsrt.repo` is
unfiltered or not, we can drop `unfiltered()` in other places.

rebase: remove complex unhiding code
This is similar to Martin von Zweigbergk's previous patch [1].
Previous patches are adding more `.unfiltered()` to the rebase code. So I
wonder: are we playing whack-a-mole regarding on `unfiltered()` in rebase?
Thinking about it, I believe most of the rebase code *should* just use an
unfiltered repo. The only exception is before we figuring out a
`rebasestate`. This patch makes it so. See added comment in code for why
that's more reasonable.
This would make the code base cleaner (not mangling the `repo` object),
faster (no need to invalidate caches), simpler (less LOC), less error-prone
(no need to think about what to unhide, ex. should we unhide wdir p2? how
about destinations?), and future proof (other code may change visibility in
an unexpected way, ex. directaccess may make the destination only visible
when it's in "--dest" revset tree).

rebase: use unfiltered repo when loading state
Before this patch, `rebase --abort` may fail to do the cleanup:
$ hg rebase --abort
rebase aborted (no revision is removed, only broken state is cleared)
The added test case makes sure `--abort` works in this case.

rebase: do not crash rebasing merge with a parent having hidden successor
The added test will crash with previous code.

changegroup: fix to allow empty manifest parts
The current chunk reading algorithm relied on counting the number of empty
chunks and comparing it to the number of chunk lists it expected (1 list of
files for cg1 and cg2, and 1 list of files + 1 list of trees for cg3). This
implicitly assumed that both the changelog part and the manifestlog part were
never empty (since them being empty would cause it to count it as one list being
done, and screw up the count). In our treemanifest code, the manifest section
could be empty, so we need to handle that case.
This patches refactors that code to be more explicit about how it counts the
expected parts.

wrapcommand: use functools.partial
Like the previous patch, this helps remove noises in traceback.
Practically, this removes another 6 lines in `rebase -s . -d .` traceback in
my setup:

wrapfunction: use functools.partial if possible
Every `extensions.bind` call inserts a frame in traceback:
... in closure
return func(*(args + a), **kw)
which makes traceback noisy.
The Python stdlib has a `functools.partial` which is backed by C code and
does not pollute traceback. However it does not support instancemethod and
sets `args` attribute which could be problematic for alias handling.
This patch makes `wrapfunction` use `functools.partial` if we are wrapping a
function directly exported by a module (so it's impossible to be a class or
instance method), and special handles `wrapfunction` results so alias
handling code could handle `args` just fine.
As an example, `hg rebase -s . -d . --traceback` got 6 lines removed in my
setup:
File "hg/mercurial/dispatch.py", line 898, in _dispatch
