The regtests are using the "feature()" predicate but this one can only rely on build-time options. It would be nice if some runtime-specific options could be detected at boot time so that regtests could more flexibly adapt to what is supported (capabilities, splicing, etc). Similarly, certain features that are currently enabled with USE_XXX could also be automatically detected at build time using ifdefs and would simplify the configuration, but then we'd lose the feature report in the feature list which is convenient for regtests. This patch makes sure that haproxy -vv shows the variable's contents and not the macro's contents, and adds a new hap_register_feature() to allow the code to register a new keyword.
