4d3b6506d3 librpc: Remove the gensec dependency from library dcerpc-binding
This means yet another library, but having to depend on gensec just

7d2faa2714 librpc: Lower dcesrv_call_dispatch_local() errors from DBG_ERR to DBG_INFO
Before merging the s3 and s4 RPC servers the rpcint_dispatch function
was not logging any error.

This commit lowers from DBG_ERR to DBG_INFO the importance of error
messages when dispatching local RPC calls. There are some situations
where RPC functions return RPC faults and this is not a fatal condition.
One example is _lsa_QueryInfoPolicy2.

This change prevents a noisy error logged when winbindd tries to connect to
its primary domain in the nt4_member and ad_member test environments:

302098c325 rpc: avoid undefined behaviour when parsing bindings
If the binding string ends with "[", we were setting options to an
empty string, then asking for 'options[strlen(options)-1]', which
UBSan dosn't like because the offset evaluates to (size_t)0xFFFFF...
causing pointer overflow.

I believe this is actually well defined in practice, but we don't want
to be in the habit of leaving sanitiser warnings in code parsing
untrusted strings.

existing uses of str(n?)casecmp, add #undef lines to source files where
