Add unit tests for debug_get_bool_option and debug_get_num_option
Merge env_var_as_boolean and debug_get_bool_option and implement
env_var_as_boolean with debug_get_bool_option in a stricter side.
Merge env_var_as_unsigned and debug_get_num_option and implement
env_var_as_unsigned with debug_get_num_option in a stricter side.
Move debug_control, parse_debug_string, parse_enable_string,
comma_separated_list_contains from debug.* to u_debug.*
Main changes:
os_get_option() is used instead of getenv() for env_var_as_boolean
and env_var_as_unsigned;
also debug_get_bool_option() has logic like "true" always if not "false";
env_var_as_boolean() now uses different logic:
if env variable is neither "true" nor "false" returns the default value,
we left the second one; but if you want the behavior to be the same as in
the old version of debug_get_bool_option() use dfault=true
