Fix autotools rules to properly include help placeholders (#1072033)

Turns out we can't use /usr/share/doc/anaconda/help because during
image generation the RPM transaction is running with nodocs and
all docs are removed.

Add VNC to the ostree test arguments.

It's hanging for some reason, but I can't determine why without using vnc.
Remove the last references to tzmapdata
We now need to specify an epoch for the python-blivet version requires.

Currently it's not defined, which means it's 0, which means any python-blivet
build with an epoch of 1 is new enough.  Of course, that's not what we want.
Trim changelog entries from spec file
Remove duplicates when adding new devices (#887526)

bootLoaderDevices is added automatically so if the device that was just
added is one of them we were ending up with two of them. This makes sure
there aren't any duplicates.
Ignore partition start if there is a biosboot partition (#1044849)

A biosboot partition can be anywhere on the disk, it doesn't need to be
the first. When there is one the first partition can start lower than
without one.
Only allow one anaconda instance (#1146735)

If the PID file is stale, remove it and retry.  Display a graphical
error dialog if we're in the sort of environment that can display
graphical dialogs early on, otherwise just print a message and bomb out.
Add a test case for if all anaconda's Requires exist.

BuildRequires should be taken care of by the other test cases.  This one
handles all the other stuff we need at runtime.
New version - 22.8
Disable the ntp service with --nontp (#1135768)

Both un-enable and disable the ntp service when ntp is turned off.  We
can't always assume that ntp will be turned off by default on the
installed system, because of live images.
Allow recursive lightbox calls (#1147337)

This way a lightbox on top of a lightbox (such as an error window on top
of a dialog, or multiple dialogs accidentally being opened on top of one
another) only adds one overlay image, and turning the lightbox off on
the way back out doesn't crash.
Fix a race between checking for Gtk.main_level and running Gtk.main

Ensure that if an exception occurs before the GUI has started, causing
meh to start its own Gtk main loop, that the GUI really doesn't start
another Gtk main loop.
Skip running efibootmgr for noefi mode (#1047904)

noefi on the cmdline tells the kernel not to make runtime EFI calls so
Anaconda should skip trying to run efibootmgr.

Note that noefi does NOT mean do a BIOS install. To do that the system
needs to be booted in CSM mode.
Make device/fs type comboboxes take less space

There's no need to have them as big as possible.
A function for resolving date format and order

It's not that easy to get right order of date fields (year, month, day) and
their formats so we should better have it in a standalone function with tests.

Make the date format locale-dependent in our GUI (#1044233)

The y/m/d order varies among locales and so do the delimiters between the date
fields.
Add nombr to anaconda to suppress updating MBR (#886502)

This patch adds the boot parameter "nombr" to suppress updating the MBR while
still completely installing grub2 and creating the grub.cfg file.  The actual
suppression adds "--grub-setup=/bin/true" to the execution of
"/sbin/grub-install"

Kickstart, regular, and live installs are supported.
Remove unused variables in the datetime_spoke.py module

Introduced in commit e9cbca2eab655475195653850f4b6cc9792b7af2.
Switch to using the new help content path (#1072033)
