- Add tcl-refchan-mode-needed.patch to allow refchans to be opened
  for neither reading nor writing, but still handle events.

- skip more tests with qemu_user builds (e.g. riscv64)

- Remove the SQLite extension and package it as a subpackage of
  sqlite3 to have only a single copy and keep it more up to date
  (bsc#1195773).
- Clean up the lib dependencies in tclConfig.sh and tcl.pc.
