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:

Create the repo with a couple of revisions of both large and normal
files.
Test status and dirstate of largefiles and that summary output is correct.

Test messages and exit codes for remove warning cases

  $ hg remove -A large1
  not removing large1: file still exists
  [1]
  $ echo 'modified' > large1
  $ hg remove large1
  not removing large1: file is modified (use -f to force removal)

Test archiving the various revisions.  These hit corner cases known with

  $ hg archive -r 4 ../archive4

Commit corner case: specify files to commit.

  $ cd ../a
  $ echo normal3 > normal3
  $ echo large3 > large3
  $ echo normal4 > sub/normal4
  $ echo large4 > sub/large4
  $ hg commit normal3 large3 sub/normal4 sub/large4 -m "edit files again"

  $ cat normal3

  $ cat large3

  $ cat sub/large4

One more commit corner case: commit from a subdirectory.

  $ cd ../a
  $ echo normal33 > normal3
  $ echo large33 > large3
  $ echo normal44 > sub/normal4
  $ echo large44 > sub/large4
  $ cd sub
  $ hg commit -m "edit files yet again"

Committing standins is not allowed.

  $ cd ..
  $ echo large3 > large3
  $ hg commit .hglf/large3 -m "try to commit standin"
  abort: file ".hglf/large3" is a largefile standin
  (commit the largefile itself instead)

Corner cases for adding largefiles.

  $ echo large5 > large5
  $ hg add --large large5
  $ hg add --large large5
  large5 already a largefile
  $ mkdir sub2
  $ echo large6 > sub2/large6
  $ echo large7 > sub2/large7
  $ hg add --large sub2
  adding sub2/large6 as a largefile
  adding sub2/large7 as a largefile
  $ hg st
  M large3
  A large5

Committing directories containing only largefiles.

  $ mkdir -p z/y/x/m
  $ touch z/y/x/m/large1

(and a bit of log testing)

  $ hg log -T '{rev}\n' z/y/x/m/large1

  $ hg log -T '{rev}\n' z/y/x/m  # with only a largefile

  $ hg rollback --quiet

  $ rm -rf z
  $ hg ci -m "standin" .hglf

Test "hg status" with combination of 'file pattern' and 'directory
pattern' for largefiles:

  $ hg status sub2/large6 sub2
  A sub2/large6
  A sub2/large7

Config settings (pattern **.dat, minsize 2 MB) are respected.

  $ echo testdata > test.dat
  $ dd bs=1k count=2k if=/dev/zero of=reallylarge > /dev/null 2> /dev/null
  $ hg add
  adding reallylarge as a largefile
  adding test.dat as a largefile

Test that minsize and --lfsize handle float values;
also tests that --lfsize overrides largefiles.minsize.
(0.250 MB = 256 kB = 262144 B)

  $ dd if=/dev/zero of=ratherlarge bs=1024 count=256 > /dev/null 2> /dev/null
  $ dd if=/dev/zero of=medium bs=1024 count=128 > /dev/null 2> /dev/null
  $ hg --config largefiles.minsize=.25 add
  adding ratherlarge as a largefile
  adding medium
  $ hg forget medium
  $ hg --config largefiles.minsize=.25 add --lfsize=.125
  adding medium as a largefile
  $ dd if=/dev/zero of=notlarge bs=1024 count=127 > /dev/null 2> /dev/null
  $ hg --config largefiles.minsize=.25 add --lfsize=.125
  adding notlarge
  $ hg forget notlarge

Test forget on largefiles.

  $ hg forget large3 large5 test.dat reallylarge ratherlarge medium
  $ hg commit -m "add/edit more largefiles"
  Invoking status precommit hook
  A sub2/large6
  A sub2/large7

Purge with largefiles: verify that largefiles are still in the working
dir after a purge.

  $ hg purge --all
  $ cat sub/large4
  large44
  $ cat sub2/large6
  large6
  $ cat sub2/large7
  large7

Test addremove: verify that files that should be added as largefiles are added as
such and that already-existing largefiles are not added as normal files by
accident.

  $ rm normal3
  $ rm sub/large4
  $ echo "testing addremove with patterns" > testaddremove.dat
  $ echo "normaladdremove" > normaladdremove
  $ hg addremove
  removing sub/large4
  adding testaddremove.dat as a largefile
  removing normal3
  adding normaladdremove

Test addremove with -R

  $ hg up -C

  1 largefiles updated, 0 removed
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ rm normal3

More rebase testing, but also test that the largefiles are downloaded from
'default-push' when no source is specified (issue3584). (The largefile from the
pulled revision is however not downloaded but found in the local cache.)
Largefiles are fetched for the new pulled revision, not for existing revisions,
rebased or not.
