graphlog: refactor revset() to return revisions

When --follow and --rev are passed, --follow actual behaviour depends on the
input revision sequence defined by --rev. If --rev is not passed, the default
revision sequence depends on the presence of --follow. It means the revision
sequence generation is part of log logic and must be wrapped. The issue
described above is fixed in following patches.

  $ hg init
  $ echo This is file a1 > a
  $ echo This is file b1 > b
  $ hg add a b
  $ hg commit -m "commit #0"
  $ echo This is file b22 > b
  $ hg commit -m "comment #1"
  $ hg update 0
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ rm b
  $ hg commit -A -m "comment #2"
  removing b
  created new head
  $ hg update 1
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg update
  abort: crosses branches (merge branches or update --check to force update)
  [255]
  $ hg update -c
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ mv a c

In theory, we shouldn't need the "-y" below, but it prevents this test
from hanging when "hg update" erroneously prompts the user for "keep
or delete".

Should abort:

  $ hg update -y 1
  abort: crosses branches (merge branches or use --clean to discard changes)
  [255]
  $ mv c a

Should succeed:

  $ hg update -y 1
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
