Option setup / normalization helpers in lib/core/option.py.

These exercise the (mostly) pure config-massaging functions that parse, validate
and normalize user-supplied option values into the canonical conf.*/kb.* shapes
that the rest of sqlmap relies on - WITHOUT touching the network, the DBMS, the
filesystem (beyond what bootstrap already set up) or any interactive prompt.

option.py mutates the global conf/kb singletons aggressively, so every test that
writes a conf/kb field saves and restores it via the _preserve() helper so the
shared state stays pristine for the other test files in the suite.
