simplemerge: move conflict warning message to filemerge

The current output for a failed merge with conflict markers looks something like:

  merging foo
  warning: conflicts during merge.
  merging foo incomplete! (edit conflicts, then use 'hg resolve --mark')
  merging bar
  warning: conflicts during merge.
  merging bar incomplete! (edit conflicts, then use 'hg resolve --mark')

We're going to change the way merges are done to perform all premerges before
all merges, so that the output above would look like:

  merging foo
  merging bar
  warning: conflicts during merge.
  merging foo incomplete! (edit conflicts, then use 'hg resolve --mark')
  warning: conflicts during merge.
  merging bar incomplete! (edit conflicts, then use 'hg resolve --mark')

The 'warning: conflicts during merge' line has no context, so is pretty
confusing.

This patch will change the future output to:

  merging foo
  merging bar
  warning: conflicts while merging foo! (edit, then use 'hg resolve --mark')
  warning: conflicts while merging bar! (edit, then use 'hg resolve --mark')

The hint on how to resolve the conflicts makes this a bit unwieldy, but solving
that is tricky because we already hint that people run 'hg resolve' to retry
unresolved merges. The 'hg resolve --mark' mostly applies to conflict marker
based resolution.

Set up a base, local, and remote changeset, as well as the working copy state.
Files names are of the form base_remote_local_working-copy. For example,
content1_content2_content1_content2-untracked represents a
file that was modified in the remote changeset, left untouched in the
local changeset, and then modified in the working copy to match the
remote content, then finally forgotten.

  $ hg init

Create base changeset

  $ python $TESTDIR/generate-working-copy-states.py state 3 1
  $ hg addremove -q --similarity 0
  $ hg commit -qm 'base'

Create remote changeset

  $ python $TESTDIR/generate-working-copy-states.py state 3 2
  $ hg addremove -q --similarity 0
  $ hg commit -qm 'remote'

Create local changeset

  $ hg update -q 0
  $ python $TESTDIR/generate-working-copy-states.py state 3 3
  $ hg addremove -q --similarity 0
  $ hg commit -qm 'local'

Set up working directory

  $ python $TESTDIR/generate-working-copy-states.py state 3 wc
  $ hg addremove -q --similarity 0
  $ hg forget *_*_*_*-untracked
  $ rm *_*_*_missing-*

  39 files updated, 3 files merged, 8 files removed, 10 files unresolved
  use 'hg resolve' to retry unresolved file merges or 'hg update -C .' to abandon
  [1]

Check which files need to be resolved (should correspond to the output above).
This should be the files for which the base (1st filename segment), the remote
(2nd segment) and the working copy (4th segment) are all different.

Interestingly, one untracked file got merged and added, which corresponds to the
odd 'if force and branchmerge and different' case in manifestmerge().

  $ hg resolve -l
  U content1_content2_content1_content4-tracked
  R content1_content2_content2_content1-tracked
  U content1_content2_content2_content4-tracked
  R content1_content2_content3_content1-tracked
  U content1_content2_content3_content3-tracked
  U content1_content2_content3_content4-tracked
  R content1_content2_missing_content1-tracked
  U content1_content2_missing_content4-tracked
  U missing_content2_content2_content4-tracked
  U missing_content2_content3_content3-tracked
  U missing_content2_content3_content4-tracked
  U missing_content2_missing_content4-tracked
  U missing_content2_missing_content4-untracked

Check status and file content

Some files get added (e.g. content1_content2_content1_content1-untracked)

It is not intuitive that content1_content2_content1_content4-tracked gets
merged while content1_content2_content1_content4-untracked gets overwritten.
Any *_content2_*-untracked triggers the modified/deleted prompt and then gets
overwritten.

A lot of untracked files become tracked, for example
content1_content2_content2_content2-untracked.

*_missing_missing_missing-tracked is reported as removed ('R'), which
doesn't make sense since the file did not exist in the parent, but on the
other hand, merged-in additions are reported as modifications, which is
almost as strange.

missing_missing_content3_missing-tracked becomes removed ('R'), even though
the remote side did not touch the file
