Now that "thread/frame apply" have been converted to the gdb::option
framework, these functions are no longer used.
For a while, I thought about keeping the unit tests, by making a local
version of parse_flags_qcs in the unit tests file. But all that would
really test that is used by GDB itself, is the validate_flags_qcs
function. So in the end, I went through all the unit tests, and
converted any that wasn't already covered to gdb.base/options.exp
tests. And those have all already been added in previous patches.
