From Gerri:

Fixes for report #51364
  - In XrdProofdNetMgr, validate the proof.conf file only at the moment when it is really used
  - When parsing configuration directives, use XrdOucStream::GetWord() instead of XrdOucStream::GetToken()
    so that variable substitution is fully active; this allows to write more concise and less error-prone
    configuration files
