[companion-integrate] RTI - Update of SFWcurl (curl) Packages

[Steve Christensen]

This is a RTI for an update of the SFWcurl (curl) package to version 7.16.3.

A minor patch to the vorbis-tools source was also needed due to its 
dependency on curl.

The webrev is at

The code has been reviewed by Paul Cunningham (see companion-discuss).

The changes are:

1.  Update of source and version numbers.
2.  Update of copyrights and removal of sccs ids.
3.  Re-versioning of libcurl files.
4.  Addition of curlver.h to /opt/sfw/include/curl
5.  Update of man pages
6.  Addition of a METADATA file for curl
7.  With the update of curl, a known patch to vorbis-tools is required.

This code builds cleanly in a nightly build on NV 62 and the package
installs properly creating a working curl executable.
