Log Message:
Update chat/loudmouth to 1.5.3.  Changes to 1.5.1 are:

There have been many changes since the previous official release, 1.4.3, which
was published 7 years ago, so we'll only mention a few of them:
- This Loudmouth release is compatible with current Glib/GTK libraries
- The internal asyncns copy has been removed
- The security has been improved in several ways:
  - Certificates: added checking of SAN(s) when CN does not match and fixed CN
    wildcard handling
  - SSL 2 and 3 have been deactivated; TLS 1.1 and 1.2 have been activated
  - Use the default cipher suite of GnuTLS
  - New API: Implementation of lm_ssl_set_ca and lm_ssl_set_cipher_list
    This enables the application to choose additional CA certificates to trust
    as well as the cipher suites which are used by OpenSSL or GnuTLS
- Many resolver and parser issues have been fixed

I can't find a subsequent changelog for 1.5.1 to 1.5.3 but assume "bugs \ 
fixed".
