Summary:
This is a bit icky, but it's the easiest way to solve a problem
I've seen a few times, the latest case being
https://openqa.stg.fedoraproject.org/tests/1664 . In that test,
_console_wait_login logs in to tty1 as user, then uefi_
postinstall wants to switch to tty3 and log in as root. When
it does that, sometimes the check_screen loop in console_login
gets hit before the display has actually switched from tty1 to
tty3, so everything gets out of sync.
An alternative would be to have root_console check that it's
either logged in or at the correct tty before handing off to
console_login, but that starts duplicating stuff, and it breaks
in the case the target tty is logged in as a user and the login
prompt is no longer visible...
Test Plan:
Check all tests run as normal, and maybe run UEFI
tests a few times to see that the bug no longer happens (but
it's hard to reliably trigger it anyway).

Summary:
Root console in anaconda got broken by RHBZ #1222413 - no
shell on tty2. Decided to clean up console use in general as
part of fixing it.
This creates a class 'fedorabase' and has 'anacondalog' and
'fedoralog' both inherit from it. boot_to_login_screen is
moved there (as it seems appropriate) and it has a new
method, console_login, which basically handles 'get me a
shell on a console': if we're already at one it returns,
if not it'll type the user name and the password *if
necessary* (sometimes it's not) and return once it sees a
prompt. It takes a hash of named parameters for user,
password and 'check', which is whether it should die if it
fails to reach a console or not (some users don't want it
to).
anacondalog and fedoralog both get 'root_console' methods
which do something appropriate and then call
console_login; both have a hash of named parameters,
anacondalog's version only bothers with 'check', while
fedoralog's also accepts 'tty' to pick the tty to use.
This also adjusts all things which try to get to a console
prompt to use either root_console or console_login as
appropriate.
It also tweaks the needle tags a bit, drops some unneeded
needles, and adds a new 'user console prompt' needle; we
really just need two versions of the root prompt needle
and two of the user prompt needle (one for <F23, one for
F23+ - the console font changed in F23, and the @ character
at least doesn't match between the two). I think we still
need the <F23 case for upgrade tests, for now.
Test Plan:
Do a full test run and see that more tests
succeed. I've done a run on happyassassin with a hack to
workaround the SELinux issue for interactive installs,
and the results look good. I also fiddled about a bit to
test some different cases, like forcing a failure in a
live test to test post_fail_hook (and hence root_console)
in that scenario, and forcing failures after some console
commands had been run to check that it DTRT when we've
already reached a console, etc.
