* treewide: http -> https sources
This updates the source urls of all top-level packages from http to
https where possible.
* buildtorrent: fix url and tab -> spaces
We do a few more things:
- libmarble and libdivecomputer with the subsurface patches have both been
inlined for 2 reasons:
a) nobody else is using these forks
b) they need to be updated in lockstep with subsurface
- instead of building libmarble against qtquick1, we now build using
qtquickcontrols (qtquick2)
- getting rid of qtquick1 also allows us to use the default qt (currently 5.6)
- we get rid of some hacks to deal with library dependencies
- instead of manually overriding various phases, we simply use cmakeFlags to
pass proper parameters
