largefiles: check whether specified patterns are related to largefiles strictly

current 'lfiles_repo.status()' implementation examines whether
specified patterns are related to largefiles in working directory (not
to STANDIN) or not by NOT-EMPTY-NESS of below list:

    [f for f in match.files() if f in lfdirstate]

but it can not be assumed that all in 'match.files()' are file itself
exactly, because user may only specify part of path to match whole
under subdirectories recursively.

above examination will mis-recognize such pattern as 'not related to
largefiles', and executes normal 'status()' procedure. so, 'hg status'
shows '?'(unknown) status for largefiles in working directory unexpectedly.

this patch examines relation of pattern to largefiles by applying
'match()' on each entries in lfdirstate and checking wheter there is
no matched entry.

it may increase cost of examination, because it causes of full scan of
entries in lfdirstate.

so this patch uses normal for-loop instead of list comprehensions, to
decrease cost when matching is found.

Create the repo with a couple of revisions of both large and normal
files, testing that status correctly shows largefiles and that summary output
is correct.

  $ hg init a
  $ cd a
  $ mkdir sub
  $ echo normal1 > normal1
  $ echo normal2 > sub/normal2

Remove both largefiles and normal files.
 
  $ hg remove normal1 large1
  $ hg commit -m "remove files"
  Invoking status precommit hook
  R large1
  R normal1
  $ ls
  sub
  $ echo "testlargefile" > large1-test

  $ hg rm large1-test

  $ hg st

  $ hg forget large1-test
  $ hg st

Copy both largefiles and normal files (testing that status output is correct).

  $ hg cp sub/normal2 normal1
  $ hg cp sub/large2 large1
  $ hg commit -m "copy files"
  Invoking status precommit hook

  $ cat normal1

Test moving largefiles and verify that normal files are also unaffected.

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

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/normal4

  $ 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"

  (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)

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

  $ 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

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

  $ rm sub/large4
  $ echo "testing addremove with patterns" > testaddremove.dat

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

  A a/b/c/x/y.normal.txt

(1) no pattern: no performance boost
  $ 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

(5) mixed case: no performance boost
