Log Message:
* Version 3.5.9 (released 2017-02-12)

** libgnutls: Removed any references to OpenPGP functionality in documentation,
   and marked all functions in openpgp.h as deprecated. That functionality
   is considered deprecated and should not be used for other reason than
   backwards compatibility.

** libgnutls: Improve detection of AVX support. In certain cases when
   when the instruction was available on the host, but not on a VM running
   gnutls, detection could fail causing illegal instruction usage.

** libgnutls: Added support for IDNA2008 for internationalized DNS names.
   If gnutls is compiled using libidn2 (the latest version is recommended),
   it will support IDNA2008 instead of the now obsolete IDNA2003 standard.
   Resolves gitlab issue 150. Based on patch by Tim Ruehsen.

** p11tool: re-use ID from corresponding objects when writing certificates.
   That is, when writing a certificate which has a corresponding public key,
   or private key in the token, ensure that we use the same ID for the
   certificate.

** API and ABI modifications:
gnutls_idna_map: Added
gnutls_idna_reverse_map: Added
