errors: introduce InputError and use it from commands and cmdutil

This patch introduces a `InputError` class and replaces many uses of
`error.Abort` by it in `commands` and `cmdutil`. This is a part of
https://www.mercurial-scm.org/wiki/ErrorCategoriesPlan. There will
later be a different class for state errors (to raise e.g. when
there's an unfinished operation). It's not always clear when one
should report an input error and when it should be a state error. We
can always adjust later if I got something wrong in this patch (but
feel free to point out any you notice now).

Make sure it throws error while passing --continue or --abort with --dry-run
  $ hg rebase -s 2 -d 6 -n --continue
  abort: cannot specify both --continue and --dry-run
  [255]
  $ hg rebase -s 2 -d 6 -n --abort
  abort: cannot specify both --abort and --dry-run
  [255]

Check dryrun gives correct results when there is no conflict in rebasing
  $ hg rebase -s 2 -d 6 -n
  starting dry-run rebase; repository will not be changed

Check it gives error when both --dryrun and --confirm is used:
  $ hg rebase -s 2 -d . --confirm --dry-run
  abort: cannot specify both --confirm and --dry-run
  [255]
  $ hg rebase -s 2 -d . --confirm --abort
  abort: cannot specify both --abort and --confirm
  [255]
  $ hg rebase -s 2 -d . --confirm --continue
  abort: cannot specify both --continue and --confirm
  [255]

Test --confirm option when there are no conflicts:
  $ hg rebase -s 2 -d . --keep --config ui.interactive=True --confirm << EOF
  > n
  > EOF
