This is the first round of breakpoint code rework and cleanup. Here we split up architecture validation and commit so that we don't mess up with architecture internals in case attributes are rejected or slot can't be reserved. It also unconfuse the code in general.

HEAD: 0a788eff09988e58708c4a3ce7b8441ce3e7df95
Thanks, Frederic ---
