Refactor all specs

[TomaszGasior]

https://docs.fedoraproject.org/en-US/packaging-guidelines/#_package_dependencies

Task to do:

• Run rpmlint on each spec
• Choose %define vs %global
• Clean up dependencies: remove unneeded, use language-specific package definition instead of bare package names
• Use macros when possible instead of hard coding
• Choose mkdir, cp and friends vs install and choose bare command vs commands from macros
• Permissions and directory definitions in %files section
• Get rid of %global debug_package %{nil} and other magic constants if possible, document otherwise
• Use %{name} in %files section when possible
• Build debug packages
