*) Platform was no longer recognized as a attribute of Options. Used waf
Utils call to obtain unversioned platform name.
*) Task classes renamed from <taskname>_task to <taskname>.
Waf was not finding the classes when named with _task suffix.
*) Waf removed check option for 'type_name' check.
Added explicit embedded code snippet based on previous Waf versions to perform uint128 checks.
*) Waf source attribute is now strings, need to convert to nodes to retrieve parent node.
# Orig 1.8.19 testdir = self.source[-1].parent.path_from(self.bld.srcnode)
testdir = self.to_nodes(self.source[-1])[0].parent.path_from(self.bld.srcnode)
This is a massive upgrade removing almost all pre-waf 1.6 script code. In addition, this does away with custom pkgconfig.py script for making .pc files and replaces it with waf's builtin mechanism.
Massive thanks to Alex Afanasyev for ideas and bugfixing, to Alina Quereilhac for bugfixing and testing, and to Tom Henderson for thorough testing.
