evolve: improve error messages when conflicts occur

This patch improves the error messages when conflicts occur.

First, we drop the line 'evolution failed', that is not the best line we can
show and evolution didn't failed, it's just interrupted by the conflicts and
when user will run `hg evolve --continue`, things will be fine. I still remember
when I first saw 'evolution failed', I got a bit scare as am I in a recoverable
position or not. So let's drop this scary line.

Second, we replace the error messages to say `resolve conflicts and see
help-topic`. The help topic was added recently and documents all the three flags
very well. Addition of tests also showed that all the three flags works fine
with all the three instability type. So we should advertise them more.

Third, we now raise the error with our error message rather than raising
MergeFailure and having evolution related text in hint or stderr above. This
increase the focus on the error message we want to show.

After this patch, I think error messages by evolve in case of conflicts will be
same in every case.

Basic tests
===========
(no criss cross merge)

Smoke tests
-----------

Starts with a "simple case"

  $ hg init repo_A
  $ cd repo_A
  $ hg debugbuilddag '
  > ..:g   # 2 nodes, tagged "g"
  > <2.:h   # another node base one -2 -> 0, tagged "h"
  > *1/2:m # merge -1 and -2 (1, 2), tagged "m"
  > <2+2:i # 2 nodes based on -2, tag head as "i"
  > .:c    # 1 node tagged "c"
  > <m+3:a # 3 nodes base on the "m" tag
  > <2.:b  # 1 node based on -2; tagged "b"
  > <m+2:d # 2 nodes from "m" tagged "d"
  > <2.:e  # 1 node based on -2, tagged "e"
  > <m+1:f # 1 node based on "m" tagged "f"
