tests: disable `test-git-interop.t` with a requirements directive

Note that the failures in this test affect all platforms.

I don't like this, but the test has been broken for awhile because of dirstate
API changes, and nobody noticed because the required `pygit2` package isn't
installed on the CI systems.  I did install it on the mac CI system, which
triggers this failure.  Disabling it is no worse than not running it due to the
missing package, but at least this way the CI systems can get the package
installed, and the test can be enabled and fixed eventually, without needing to
alter the CI systems.

The feature here is kind of abused.  I thought about adding one specifically to
test for CI, but didn't feel like doing it at this point.  Maybe if we need to
disable things to get the Windows CI off the ground (but that likely requires
testing for CI + platform).

Second scenario with two repos:

  $ cd ..
  $ hg init r1
  $ cd r1
  $ mkdir a
  $ echo foo > a/f
  $ hg add a
  adding a/f
  $ hg ci -m "a/f == foo"
  $ cd ..

  $ hg clone r1 r2
  updating to branch default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cd r2
  $ hg mv a b
  moving a/f to b/f
  $ echo foo1 > b/f
  $ hg ci -m" a -> b, b/f == foo1"
  $ cd ..

  $ cd r1
  $ mkdir a/aa
  $ echo bar > a/aa/g
  $ hg add a/aa
  adding a/aa/g
  $ hg ci -m "a/aa/g"
  $ hg pull ../r2
  pulling from ../r2
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files (+1 heads)
  new changesets 7d51ed18da25
  1 local changesets published
  (run 'hg heads' to see heads, 'hg merge' to merge)

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

  $ hg st -C
  M b/f
  A b/aa/g
    a/aa/g
  R a/aa/g
  R a/f

  $ cd ..

Test renames to separate directories

  $ hg init a
  $ cd a
  $ mkdir a
  $ touch a/s
  $ touch a/t
  $ hg ci -Am0
  adding a/s
  adding a/t

Add more files

  $ touch a/s2
  $ touch a/t2
  $ hg ci -Am1
  adding a/s2
  adding a/t2

Do moves on a branch

  $ hg up 0
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ mkdir s
  $ mkdir t
  $ hg mv a/s s
  $ hg mv a/t t
  $ hg ci -Am2
  created new head
  $ hg st --copies --change .
  A s/s
    a/s
  A t/t
    a/t
  R a/s
  R a/t

Merge shouldn't move s2, t2

  $ hg merge
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg st --copies
  M a/s2
  M a/t2

Try the merge in the other direction. It may or may not be appropriate for
status to list copies here.

  $ hg up -C 1
  4 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ hg merge
  2 files updated, 0 files merged, 2 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg st --copies
  M s/s
  M t/t
  R a/s
  R a/t

  $ cd ..


Test that files are moved to a new directory based on the path prefix that
matches the most. dir1/ below gets renamed to dir2/, and dir1/subdir1/ gets
renamed to dir2/subdir2/. We want dir1/subdir1/newfile to move to
dir2/subdir2/ (not to dir2/subdir1/ as we would infer based on just the rename
of dir1/ to dir2/).

  $ hg init nested-renames
  $ cd nested-renames
  $ mkdir dir1
  $ echo a > dir1/file1
  $ echo b > dir1/file2
  $ mkdir dir1/subdir1
  $ echo c > dir1/subdir1/file3
  $ echo d > dir1/subdir1/file4
  $ hg ci -Aqm initial
  $ hg mv dir1 dir2
  moving dir1/file1 to dir2/file1
  moving dir1/file2 to dir2/file2
  moving dir1/subdir1/file3 to dir2/subdir1/file3
  moving dir1/subdir1/file4 to dir2/subdir1/file4
  $ hg mv dir2/subdir1 dir2/subdir2
  moving dir2/subdir1/file3 to dir2/subdir2/file3
  moving dir2/subdir1/file4 to dir2/subdir2/file4
  $ hg ci -m 'move dir1/ to dir2/ and dir1/subdir1/ to dir2/subdir2/'
  $ hg co 0
  4 files updated, 0 files merged, 4 files removed, 0 files unresolved
  $ echo e > dir1/subdir1/file5
  $ hg ci -Aqm 'add file in dir1/subdir1/'
  $ hg merge 1
  5 files updated, 0 files merged, 4 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg files
  dir2/file1
  dir2/file2
  dir2/subdir2/file3
  dir2/subdir2/file4
  dir2/subdir2/file5
  $ cd ..
