mq: examine "pushable" of already applied patch correctly
Before this patch, "hg qselect" with --pop/--reapply may pop patches
unexpectedly, even when all of patches applied before "qselect" are
still pushable.
Strictly speaking about the condition of this issue:
- before "qselect"
- there are N applied patches
- the index of the guarded patch X in the series is less than N
- after "qselect"
- X is still guarded, and
- all of applied patched are still pushable
In the case above, "hg qselect" should keep current status, but it
actually tries to pop patches because of X.
The index in "the series" should be used to examine "pushable" of a
patch by "mq.pushablek()", but the index in "applied patches" is used,
and this may cause unexpected examination of guarded patch.
To examine "pushable" of already applied patch correctly, this patch
uses "mq.applied[i].name": "pushable" is the function introduced by
the previous patch, and it returns "mq.pushable(mq.applied[i].name)[0]".

mq: pop correct patches when changing pushable-ness of already applied ones
Before this patch, "hg qselect" with --pop/--reapply may pop incorrect
patches, because the index in "applied patches" is used to pop patches
by "mq.pop()", even though the index in "the series" should be used.
For example, when the already applied patch becomes guarded and it
follows the already guarded (= not yet applied) one, "hg qselect" is
aborted, because it tries to pop to guarded one.
This patch uses "mq.applied[i - 1].name" to pop to the patch, of which
the index in the "applied ones" is "i - 1".

mq: use "mq.applied[i].name" instead of "mq.appliedname(i)" for safety
Before this patch, "hg qselect --reapply" is aborted when "--verbose"
is specified, because "mq.appliedname()" returns "INDEX PATCHNAME"
instead of "PATCHNAME" in such case and "mq.push" can't accept the
former as the name of patch.
This patch uses "mq.applied[i].name" instead of "mq.appliedname(i)" as
the name of the patch to be pushed for safety.
Now, there is no code path using "mq.appliedname()", and it should be
removed to prevent developers from using it in the wrong way like this
issue.

mq: report correct numbers for changing "number of guarded, applied patches"
Before this patch, "hg qselect" may report incorrect numbers for
"number of guarded, applied patches has changed", because it examines
"pushable" of patches by the index not in "the series" but in "applied
patches", even though "mq.pushable()" expects the former.
To report correct numbers for changing "number of guarded, applied
patches", this patch uses the name of applied patch to examine
pushable-ness of it.
This patch also changes the result of existing "hg qselect" tests,
because they doesn't change pushable-ness of already applied patches.
This patch assumes that "hg qselect" focuses on changing pushable-ness
only of already applied patches, because:
- the report message uses not "previous" (in the series) but
"applied"
- the logic to pop patches for --pop/--reapply examines
pushable-ness only of already applied ones (in fact, there are
some incorrect code paths)

annotate: remove redundant check for empty list of annotation data
It isn't necessary because zip(*pieces) returns [] if pieces are empty,
and pieces are empty only if lines are empty.

revset: lower weight for _intlist function
The histedit command uses a revset like:
(_intlist('1234\x001235')) and merge()
Previously the optimizer gave a weight of 1.5 to the _intlist side (1 for the
function, 0.5 for the string) which caused it to process the merge() side first.
This caused it to evaluate merge against every commit in the repo, which took
2.5 seconds on a large repo.
I changed the weight of _intlist to 0, since it's a trivial calculation, which
makes it process intlist first, which makes merge apply only to the revs in the
list. Which makes the revset take 0.15 seconds now. Cutting off 2.4 seconds off
our histedit performance.
>From the revset benchmark:
revset #25: (_intlist('20000\x0020001')) and merge()
