Feature: automatic library updates

[carstene1ns]

This is actually 2 changes at once:

• ini for library definitions, makes scripting easier
• updater script using anitya, automatically run by github actions every week

Some nice features:

• Uses a supercharged ini format with replacements
• adding libraries to/updating packages.sh is easier
• no more missed library updates
  • will open a pull request for each bunch, can stay open until issues are resolved
  • parallel updates (in other PRs) will be recognized once applied
• no functional change for existing scripts

Whats missing:

• Automated PR builders on jenkins, to find breakage

Here is an example of such pull request:

Thanks for the script and automation. This will save lots of time in maintaining the libs.

Is there special handling for ICU? (E.g. Pinned to 69.1) updates to ICU are always quite hard because they library is so huge. New data file etc.

Everything else can be on latest as is usually frustration free ;)

[carstene1ns]

There is currently no special path for ICU, as well as custom platform libraries (i.e. mostly old icu). The CI/CD should notify us when there is action necessary. So IMO not worth to have special handling right now.

Most of the time one or two libraries need updates, so the changes are manageable. Currently there are 9 updates pending, which will likely break.
