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.

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
cmdpats, cmdoptions)

cmdutil: remove redundant commitfunc parameter in amend (API)
Since the redundant commit during the amend has been been removed, there is no
need for commit callback function in amend now. Therefore, this commit removes
the unused parameter "commmitfunc" which was being used for this purpose.
Test Plan:

cmdutil: remove the redundant commit during amend
There was an extra commit made during the amend operation to track the
changes to the working copy. However, this logic was written a long time back
and newer API's make this extra commit redundant. Therefore, I am removing the
extra commit. After this change, I noticed that
- Execution time of the cmdutil.amend improved by over 40%.
- Execution time of "hg commit --amend" improved by over 20%.
Test Plan:
I ensured that the all the hg tests passed after the change. I had
to fix a few tests which were aware of the extra commit made during the amend.

checknlink: use a random temp file name for checking
Previously, if `.hg/store/00manifest.d.hgtmp1` exists, hg will copy the
entire `00manifest.d` every time when appending new manifest revisions.
That could happen if Mercurial or the machine crashed when `.hgtmp1` was
just created but not deleted yet.
This patch changes the fixed name to a random generated name. To be
consistent with D468, `~` suffix was used.

copytrace: move the default copytracing algorithm in a new function
We are going to introduce a new fast heuristic based copytracing algorithm, so
lets make mergecopies the function which decides which algorithm to go with and
then calls the related function.
While I was here, I add a line in test-copy-move-merge.t saying its a test
related to the full copytracing algorithm.

copytrace: replace experimental.disablecopytrace config with copytrace (BC)
This patch replaces experimental.disablecopytrace with experimental.copytrace.
Since the words does not means the same, the default value is also changed. Now
experimental.copytrace defaults to 'on'. The new value is not boolean value as
we will be now having two different algorithms (current one and heuristics one
to be imported from fbext) so we need this to be have more options than
booleans.
The old config option is not kept is completely replaced as that was under
experimental and we don't gurantee BC to experimental things.
.. bc::
The config option for copytrace `experimental.disablecopytrace` is now
replaced with `experimental.copytrace` which defaults to `on`. If you need to
turn off copytracing, add `[experimental] copytrace = off` to your config.

largefiles: remove unused assignments from wrapfunction()
The return values from wrapfunction() were never used here. Using the
value is also a little tricky and wrappedfunction() should be
preferred, so let's just delete the assignments.
There's also a bunch of return values from wrapcommand() being
assigned to a variable here, but at least that value can be (and is
used after some of the assignments).

branches: correctly show inactive multiheaded branches
Issue being fixed here: `hg branches` incorrectly renders inactive multiheaded
branches as active if they have closed heads.
Example:
```
$ hg log --template '{rev}:{node|short} "{desc}" ({branch}) [parents: {parents}]\n'
4:2e2fa7af8357 "merge" (default) [parents: 0:c94e548c8c7d 3:7be622ae5832 ]
3:7be622ae5832 "2" (somebranch) [parents: 1:81c1d9458987 ]
2:be82cf30409c "close" (somebranch) [parents: ]
1:81c1d9458987 "1" (somebranch) [parents: ]
0:c94e548c8c7d "initial" (default) [parents: ]
$ hg branches
default 4:2e2fa7af8357
somebranch 3:7be622ae5832
```
Branch `somebranch` have two heads, the 1st one being closed (rev 2) and
the other one being merged into default (rev 3). This branch should be shown as
inactive one.
This happens because we intersect branch heads with repo heads to check branch
activity. In this case intersection in a set with one node (rev 2). This head
is closed but the branch is marked as active nevertheless.
Fix is to check branch activity by intersecting only open heads set.
Fixed output:
```
$ hg branches
default 4:2e2fa7af8357
somebranch 3:7be622ae5832 (inactive)
```
Relevant tests for multihead branches added to test-branches suite.
Implentation note about adding `iteropen` method:
At first I have tried to modify `iterbranches` is such a way that it would
filter out closed heads itself. For example it could have `closed=False`
parameter. But in this case we would have to filter closed tips as well.
Reasoning in terms of `hg branches` we actually are not allowed to do this.
Also, we need to do heads filtering only if tip is not closed itself. But if it
is - we are ok to skip filtering, because branch is already known to be inactive.
So we can't implement heads filtering in `iterbranches` in elegant way, because
we will end up with something like `closed_heads=False` or even
`closed_heads_is_tip_is_open`. Finally I decided to move this logic to the
`branches` function, adding `iteropen` helper method.
