grep: reuse the first "util.binary()" result for efficiency

Before this patch, to check whether the file in the specified revision
is binary or not, "util.binary()" is invoked via internal function
"binary()" of "hg grep" once per a line of "hg grep" output, even
though binary-ness is not changed in the same file.

This patch reuses the first "util.binary()" invocation result by
annotating internal function "binary()" with "@util.cachefunc".

reverting a rename target should revert the source

  $ hg mv a newa

  $ cd ..

  $ hg init ignored

  $ mkdir ignoreddir
  $ touch ignoreddir/file

  $ touch removed

4 ignored files (we will add/commit everything)

  $ hg st -A -X .hgignore
  I ignored
  I ignoreddir/file

  I removed
  $ hg ci -qAm 'add files' ignored ignoreddir/file ignoreddir/removed removed

  $ echo >> ignored
  $ echo >> ignoreddir/file
  $ hg rm removed ignoreddir/removed

should revert ignored* and undelete *removed

  $ hg revert -a --no-backup
  reverting ignored
  reverting ignoreddir/file (glob)
  undeleting ignoreddir/removed (glob)
  undeleting removed
  $ hg st -mardi

  $ hg up -qC
  $ echo >> ignored
  $ hg rm removed

should silently revert the named files

  $ hg revert --no-backup ignored removed

someone set up us the copies
