largefiles: keep largefiles from colliding with normal one during linear merge

Before this patch, linear merging of modified or newly added largefile
causes unexpected result, if (1) largefile collides with same name
normal one in the target revision and (2) "local" largefile is chosen,
even though branch merging between such revisions doesn't.

Expected result of such linear merging is:

  (1) (not yet recorded) largefile is kept in the working directory
  (2) largefile is marked as (re-)"added"
  (3) colliding normal file is marked as "removed"

But actual result is:

  (1) largefile in the working directory is unlinked
  (2) largefile is marked as "normal" (so treated as "missing")
  (3) the dirstate entry for colliding normal file is just dropped

(1) is very serious, because there is no way to restore temporarily
modified largefiles.

(3) prevents the next commit from adding the manifest with correct
"removal of (normal) file" information for newly created changeset.

The root cause of this problem is putting "lfile" into "actions['r']"
in linear-merging case. At liner merging, "actions['r']" causes:

  - unlinking "target file" in the working directory, but "lfile" as
    "target file" is also largefile itself in this case

  - dropping the dirstate entry for target file

"actions['f']" (= "forget") does only the latter, and this is reason
why this patch doesn't choose putting "lfile" into it instead of
"actions['r']".

This patch newly introduces action "lfmr" (LargeFiles: Mark as
Removed) to mark colliding normal file as "removed" without unlinking
it.

This patch uses "hg debugdirstate" instead of "hg status" in test,
because:

  - choosing "local largefile" hides "removed" status of "remote
    normal file" in "hg status" output, and

  - "hg status" for "large2" in this case has another problem fixed in
    the subsequent patch

This file contains testcases that tend to be related to special cases or less
common commands affecting largefile.

Each sections should be independent of each others.

test for pattern matching on 'hg status':
==============================================


to boost performance, largefiles checks whether specified patterns are
related to largefiles in working directory (NOT to STANDIN) or not.

  $ hg init statusmatch
  $ cd statusmatch

  $ mkdir -p a/b/c/d
  $ echo normal > a/b/c/d/e.normal.txt
  $ hg add a/b/c/d/e.normal.txt
  $ echo large > a/b/c/d/e.large.txt
  $ hg add --large a/b/c/d/e.large.txt
  $ mkdir -p a/b/c/x
  $ echo normal > a/b/c/x/y.normal.txt
  $ hg add a/b/c/x/y.normal.txt
  $ hg commit -m 'add files'
  Invoking status precommit hook
  A a/b/c/d/e.large.txt

  $ hg status -A
  C a/b/c/d/e.large.txt
  C a/b/c/d/e.normal.txt
  C a/b/c/x/y.normal.txt

(2) pattern not related to largefiles: performance boost
  $ hg status -A a/b/c/x
  C a/b/c/x/y.normal.txt

(3) pattern related to largefiles: no performance boost
  $ hg status -A a/b/c/d
  C a/b/c/d/e.large.txt
  C a/b/c/d/e.normal.txt

(4) pattern related to STANDIN (not to largefiles): performance boost
  $ hg status -A .hglf/a
  C .hglf/a/b/c/d/e.large.txt

(5) mixed case: no performance boost
  $ hg status -A a/b/c/x a/b/c/d
  C a/b/c/d/e.large.txt
  C a/b/c/d/e.normal.txt

Test addremove, forget and others
==============================================

Test that addremove picks up largefiles prior to the initial commit (issue3541)

  $ hg init addrm2

  $ touch large.dat
  $ touch large2.dat
  $ touch normal
  $ hg add --large large.dat
  $ hg addremove -v
  adding large2.dat as a largefile

Test that forgetting all largefiles reverts to islfilesrepo() == False
(addremove will add *.dat as normal files now)
  $ hg forget large.dat
  $ hg forget large2.dat
  $ hg addremove -v
  adding large.dat
  adding large2.dat

Test commit's addremove option prior to the first commit
  $ hg forget large.dat

  $ hg add --large large.dat
  $ hg ci -Am "commit"

shared also by largefiles b1, b2 in revision #2 and b in revision #5.

Then, entity 89e6c98d9288 is not treated as "outgoing entity" at "hg

and #5 refer it.
