* build: clang-tidy headers when building libtransmission
* chore: revert `= default` workaround
It was introduced in 6909ec0bad to fix build issues with macOS 10.14. We
no longer support that version.
* fix: clang-tidy warnings for libtransmission
* build: clang-tidy headers when building tests
* fix: clang-tidy warnings for tests
* build: clang-tidy headers when building qt
* code review: don't manually edit mime-types.h
* code review: unify variable naming for static private members
