copies: iterate over children directly (instead of parents)
Before this change we would gather all parent → child edges and iterate on
all parent, gathering copy information for children and aggregating them from
there.
They are not strict requirement for edges to be processed in that specific
order. We could also simply iterate over all "children" revision and aggregate
data from both parents at the same time. This patch does that.
It make various things simpler:
* since both parents are processed at the same time, we no longer need to
cache data for merge (see next changeset for details),
* we no longer need nested loop to process data,
* we no longer need to store partial merge data for a rev from distinct loop
interaction to another when processing merges,
* we no longer need to build a full parent -> children mapping (we only rely on
a simpler "parent -> number of children" map (for memory efficiency),
* the data access pattern is now simpler (from lower revisions to higher
revisions) and entirely predicable. That predictability open the way to
prefetching and parallel processing.
So that new iterations order requires simpler code and open the way to
interesting optimisation.
The effect on performance is quite good. In the worse case, we don't see any
significant negative impact. And in the best case, the reduction of roundtrip
to Python provide us with a significant speed. Some example below:

$ hg help cleanstatus

alias for: hg status -c
show changed files in the working directory
Show status of files in the repository. If names are given, only files
that match are shown. Files that are clean or ignored or the source of a
copy/move operation, are not listed unless -c/--clean, -i/--ignored,
-C/--copies or -A/--all are given. Unless options described with "show
only ..." are given, the options -mardu are used.
Option -q/--quiet hides untracked (unknown and ignored) files unless
explicitly requested with -u/--unknown or -i/--ignored.
Note:
'hg status' may appear to disagree with diff if permissions have
changed or a merge has occurred. The standard diff format does not
report permission changes and diff only reports changes relative to one
merge parent.
If one revision is given, it is used as the base revision. If two
revisions are given, the differences between them are shown. The --change
option can also be used as a shortcut to list the changed files of a
revision from its first parent.
The codes used to show the status of files are:
M = modified
A = added
R = removed
C = clean
! = missing (deleted by non-hg command, but still tracked)
? = not tracked
I = ignored
= origin of the previous file (with --copies)
Returns 0 on success.

options ([+] can be repeated):
-A --all show status of all files
-m --modified show only modified files
-a --added show only added files
-r --removed show only removed files
-d --deleted show only missing files
-c --clean show only files without changes
-u --unknown show only unknown (not tracked) files
-i --ignored show only ignored files
-n --no-status hide status prefix
-C --copies show source of copied files
-0 --print0 end filenames with NUL, for use with xargs
--rev REV [+] show difference from revision
--change REV list the changed files of a revision
-I --include PATTERN [+] include names matching the given patterns
-X --exclude PATTERN [+] exclude names matching the given patterns
-S --subrepos recurse into subrepositories
-T --template TEMPLATE display with template
