graphlog: use '%' only if there are *unresolved* conflicts

In 14d0e89520a2, I made graphlog use '%' for the "other" context when
there's an existing merge state. However, that has confused many
people because it shows up even if all conflicts are already resolved,
which makes it show up even after e.g. `hg update -m` with
automatically resolved conflicts. This patch makes it so we show the
'%' only if there still unresolved conflicts.

This patch replaces my earlier attempt in D8930, where I decided to
automatically clear the mergestate if there are no remaining
conflicts. That had the problem that it wouldn't let the user
re-resolve the conflicts using `hg resolve`.

Note that an in-progress "proper" merge (one that will result in a
commit with two parents, such as after `hg merge`) will already have
two dirstate parents before the commit happens. That means that both
sides of the merge will get drawn as '@' in the graph, since "is
dirstate parent" takes precedence over "is involved in merge
conflict".

Moved line may not be collected by "grep --diff" since it first filters
the contents to be diffed by the pattern. (i.e.
"diff <(grep pat a) <(grep pat b)", not "diff a b | grep pat".)
This is much faster than generating full diff per revision.

Test for showing working of allfiles flag

  $ hg init sng
  $ cd sng
  $ echo "unmod" >> um
  $ echo old > old
  $ hg ci -q -A -m "adds unmod to um"
  $ echo "something else" >> new

  $ hg grep -r "." "unmod"

Existing tracked files in the working directory are searched by default

  $ echo modified >> new
  $ echo 'added' > added; hg add added
  $ echo 'added, missing' > added-missing; hg add added-missing; rm added-missing
  $ echo 'untracked' > untracked
  $ hg rm old
  $ hg grep ''

#if symlink
Grepping a symlink greps its destination

  $ rm -f added; ln -s symlink-added added
  $ hg grep '' | grep added
  added:symlink-added

But we reject symlinks as directories components of a tracked file as
usual:

  $ mkdir dir; touch dir/f; hg add dir/f
  $ rm -rf dir; ln -s / dir
  $ hg grep ''
  abort: path 'dir/f' traverses symbolic link 'dir'
  [255]
#endif

But we can search files from some other revision with -rREV

  $ hg grep -r. mod
  um:1:unmod

  $ hg grep --diff mod
  um:0:+:unmod

Change Default of grep by ui.tweakdefaults, that is, the files not in current
working directory should not be grepp-ed on

  $ hg init ab
  $ cd ab
  $ cat <<'EOF' >> .hg/hgrc
  > [ui]
  > tweakdefaults = True
  > EOF
  $ echo "some text">>file1
  $ hg add file1
  $ hg commit -m "adds file1"
  $ hg mv file1 file2

wdir revision is hidden by default:

  $ hg grep "some"
  file2:some text

but it should be available in template dict:

  $ hg grep "some" -Tjson
  [
   {
    "date": [0, 0],
    "lineno": 1,
    "node": "ffffffffffffffffffffffffffffffffffffffff",
    "path": "file2",
    "rev": 2147483647,
    "texts": [{"matched": true, "text": "some"}, {"matched": false, "text": " text"}],
    "user": "test"
