I have pushed an update to the android libs and patches.

There is now a config for various devices, nvshield and firetv-max

No more managing SDK, NDK and arm versions and trying to remember what 
you last used. I left these much as before. firetv is at TARGETSDK 28 
and build SDK must be at least 29 use to qt build requirements.

to compile

         make CONFIG=firetv-max distclean everything

These are in android-utilities/config. Add and update these as you see fit

mariadb connector is now 3.2.6 and qt 5.15.6 among other updates

It also supports SDK and build tools to 33.

If you use NDK 24 or 25 you get a vulkan include failure when building 
ffmpeg. I didnt chase this so left the NDK at 21.4.xxxxx

This is independent of SDK and build tools used.

MIN API VERSION is also moved to the build system and not the pro file 
which is also more logical. Small commit to mythtv repo to support this.

Readme is not updated yet.

Please test and let me know if anything is wrong but I have done 
extensive building today and yesterday so hopefully I don't get surprised.

To get different SDKs and NDKs, use studio and choose configure, manage 
sdks, select hidden items and select away.

Also should I merge the datetime db update issue? My deb qt 5.15.4 and 
5.15.6 still dont have the patches required AFAICT.
