[Development] Proposal for Qt 5.10 platforms and configurations changes

[Tuukka Turunen]

Hi,

Related to the Apple platforms, could we consider the following for Qt 5.10:
- Drop the older iPhone support by removing ARMv7 from iOS (http://dorianroy.com/blog/wp-content/uploads/2016/09/iOS_Support_Matrix_v4.2.pdf)
- Consider also dropping ARMv7s support, which would allow dropping i386 simulator support
- Drop macOS 10.10 support (we are adding 10.13 or whatever, and thus supporting three latest ones means dropping one)

Yours,

	Tuukka

    Apple does not ever release updates to older release series, so since 8.3 already exists, this is guaranteed to remain 8.2.1.

    8.3.2, please.

    How do you know it won't be called macOS 11? ;)
    
    The purpose of the preview release *IS* to use it for testing so that you can say your product supports the final version (according to Apple). We should provision a VM for the first developer preview and update it throughout the beta cycle until the final release. So this should not be a problem for us with FF in August unless Qt 5.10 releases before macOS Next does.
    
    Just for the record: make sure not to drop CI for macOS 10.10 - that version is still supported in Qt 5.10. Tentative plan for 5.11 would be to drop 10.10 support.
