advice: Introduce error_resolve_conflict

Enable future callers to report a conflict and not die immediately by
introducing a new function called error_resolve_conflict.
Re-implement die_resolve_conflict as a call to error_resolve_conflict
followed by a call to die.  Consequently, the message printed by
die_resolve_conflict changes from

  fatal: 'commit' is not possible because you have unmerged files.
         Please, fix them up in the work tree ...
         ...

to

  error: 'commit' is not possible because you have unmerged files.
  hint: Fix them up in the work tree ...
  hint: ...
  fatal: Exiting because of an unresolved conflict.

Hints are printed using the same advise function introduced in
v1.7.3-rc0~26^2~3 (Introduce advise() to print hints, 2010-08-11).
