Macro procspawn::enable_test_support

macro_rules! enable_test_support {
    () => { ... };
}

Supports the use of procspawn in tests.

Due to limitations in rusttest it’s currently not easily possible to use procspawn with rusttest. The workaround is to call use this macro toplevel which will define a dummy test which is used to invoke all subprocesses.

procspawn::enable_test_support!();

Requires the test-support feature.
