Style only

Be more consistent:
   - add space between (if|while) and \(
   - place of 'break ' statement

Fix cut and paste typo in error message + remove empty lines to be consistent

follow-up to r1656549.

Instead of logging a password (which is not a good practice), clarify the associated message

* Silence compiler warning

Be less tolerant when parsing the credencial for Basic authorization. Only spaces  should be accepted after the authorization scheme. \t are also tolerated.

The current code accepts \v and \f as well.

The same behavior is already used in 'ap_get_basic_auth_pw()' which is mostly the same function as 'get_basic_auth()'.

Function used as 'apr_reslist_destructor' when calling 'apr_reslist_create()' should have the following prototype:

apr_status_t (*apr_reslist_destructor)(void *resource, void *params, apr_pool_t *pool);
