hg: pass command intents to repo/peer creation (API)

The previous commit introduced a mechanism to declare command intents.
This commit changes the repository and peer instantiation mechanism
so the intents are passed down to each repository and peer type so
they can do with them whatever they please.

Currently, nobody does anything with any intent.

Make sure that the internal merge tools (internal:fail, internal:local,
internal:union and internal:other) are used when matched by a
merge-pattern in hgrc

Make sure HGMERGE doesn't interfere with the test:

  $ unset HGMERGE

  $ hg init

Initial file contents:

  $ echo "line 1" > f
  $ echo "line 2" >> f
  $ echo "line 3" >> f
  $ hg ci -Am "revision 0"
  adding f

  $ cat f
  line 1
  line 2
  line 3

Branch 1: editing line 1:

  $ sed 's/line 1/first line/' f > f.new
  $ mv f.new f
  $ hg ci -Am "edited first line"

Branch 2: editing line 3:

  $ hg update 0
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ sed 's/line 3/third line/' f > f.new
  $ mv f.new f
  $ hg ci -Am "edited third line"
  created new head

Merge using internal:fail tool:

  $ echo "[merge-patterns]" > .hg/hgrc
  $ echo "* = internal:fail" >> .hg/hgrc

  $ hg merge
  0 files updated, 0 files merged, 0 files removed, 1 files unresolved
  use 'hg resolve' to retry unresolved file merges or 'hg merge --abort' to abandon

  $ cat f

  line 2
  third line

  $ hg stat
  M f

Merge using internal:local tool:

  $ hg update -C 2
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ sed 's/internal:fail/internal:local/' .hg/hgrc > .hg/hgrc.new
  $ mv .hg/hgrc.new .hg/hgrc

  $ hg merge
  0 files updated, 1 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)

  $ cat f

  line 2
  third line

  $ hg stat
  M f

Merge using internal:other tool:

  $ hg update -C 2
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ sed 's/internal:local/internal:other/' .hg/hgrc > .hg/hgrc.new
  $ mv .hg/hgrc.new .hg/hgrc

  $ hg merge
  0 files updated, 1 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)

  $ cat f

Merge using default tool:

  $ hg update -C 2

  $ rm .hg/hgrc

  $ hg merge

Merge using internal:union tool:

  $ hg update -C 2
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ echo "line 4a" >>f
  $ hg ci -Am "Adding fourth line (commit 4)"
  $ hg update 2
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ echo "line 4b" >>f
  $ hg ci -Am "Adding fourth line v2 (commit 5)"
  created new head

  $ echo "[merge-patterns]" > .hg/hgrc
  $ echo "* = internal:union" >> .hg/hgrc

  $ hg merge 3
