Log a warning when the LDAP authn provider is configured but an AuthLDAPURL 
isn't -- IOW, avoid silently skipping a misconfigured [or buggy?] LDAP provider.



Follow up to r1772919: update APLOGNO().

Save a few cycles.
'apr_pstrcatv' can compute the length of the new string for us.

Improve indentation

Group bit field values in order to save some memory.

Add an explicit NULL to initialise a field in an authn_provider structure, as done in all other places.  PR 60636

Since r1753257, "HEAD" method is registered into the registry hash with the M_GET ID.
(r1757672 in 2.4.x)

We iterate over all the values of the registery, so there is no need anymore to have a special case for "HEAD" in  'make_allow()'. It has its own entry now.

With the current code, we have "HEAD" 3 times in the Allow Header field.
This is because we find M_GET 2 times in the registry hash. The first one gives "GET" and "HEAD" (as the special handling), and the second "HEAD" and "HEAD" (as the special handling).


BTW, use APR_ARRAY_PUSH instead of hand coding it, in oder to have the code more readable.
