Log message:
Update to 1.3.9. Make it build with new libgnutls (which don't have the
libgnutls-config script any more).

Changes since 1.3.7:

* Preallocate and only copy the string once when escaping or unescaping it.
* Try to open both IPv6 and IPv4 listening sockets. This is required in
  case bindtov6only is 1 to also accept IPv4 connections in IPv6 mode.

Log message:
Simply and speed up buildlink3.mk files and processing.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
