Use the same version of ELFHash as QT does in qlinguist/qrelease, this version involves fewer casts and less chance of losing data in the process.
Make incrementing in command line parser start from 0, not default.

This fixes an issue in MythShutdown where telling it to check the
recording status would actually have an opposite effect of ignoring it.
Fix destroyMainWindow when gCoreContext is not created yet

Fixes #10718

Accept --enable-sdl configure option

Remove zoom on MythCenter-wide popups.
Handle new config.xml format in backup/restore.

I'm planning a more comprehensive fix, but this will allow these scripts
to work until it's ready.

The scripts remain version independent and will work with any version of
MythTV (and any version of config.xml)--unstable/development,
0.25-fixes, 0.24-fixes, or older versions.
Fix the 1299 DB upgrade (DeletedMaxAge update).

The 1299 upgrade modifies DeletedMaxAge for its new meaning, now that
AutoExpireInsteadOfDelete is always enabled.  Previously, 0 meant
"expire when out of disk space" and was the default value; but after
f78f9992 , 0 means "expire immediately" and -1 means "expire when out of
disk space."  Both before and after f78f9992, any positive value means
to expire recording files that many days after deletion.

However, the setting DeletedMaxAge was only ever written to the database
if the user enabled AutoExpireInsteadOfDelete (triggering the
DeletedExpireOptions TriggeredConfigurationGroup) and modified
DeletedMaxAge to some value other than its default of 0.  Therefore,
most users did not actually have a value for DeletedMaxAge in their
databases--whether they had enabled AutoExpireInsteadOfDelete or not.

The DB upgrade needs to change DeletedMaxAge to -1 if and only if
AutoExpireInsteadOfDelete is enabled and DeletedMaxAge has a value of 0
(or is still using the default).  Because of the condition on the
update, it did nothing for users with AutoExpireInsteadOfDelete enabled
but without a value for DeletedMaxAge in the database.  This resulted in
their systems changing from "expire when out of space" to "expire
immediately".

Thanks to Thomas Boehm and Peter on the mythtv-users mailing list for
noticing that their settings didn't carry over through the update.

Fix updating of metadata info in RecordingRule.

Only set the metadata info from the RecordingInfo if it's not already
set.  This is should be a better fix than was commited in db123034.
