REGTEST: Reg testing improvements.

Add a new target to the Makefile named "reg-tests-help" to have an idea
about how to run the reg tests from haproxy Makefile.
Handle list of levels and lists of level range passed to make with LEVEL variable.
New supported syntax:
    LEVEL=1,4     make reg-tests
    LEVEL=1-2,5-6 make reg-tests
Add two new levels 5 and 6. 5 is for broken script, 6 for experimental scripts.
