changegroup.writebundle: HG2Y support

This diff adds support to writebundle to generate a bundle2 wrapper; upcoming
diffs will add an option to write a v2 changegroup part instead of v1 in these
bundles.

This file used to contains all largefile tests.
Do not add any new tests in this file as it his already far too long to run.

It contains all the testing of the basic concepts of large file in a single block.

files.
Test status and dirstate of largefiles and that summary output is correct.

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

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 (glob)
  adding sub2/large7 as a largefile (glob)
  $ hg st
  M large3
  A large5
  A sub2/large6
  A sub2/large7

Committing directories containing only largefiles.

  $ mkdir -p z/y/x/m
  $ touch z/y/x/m/large1
  $ touch z/y/x/large2

  $ 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

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

  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.
