K 10 svn:author V 2 ed K 8 svn:date V 27 2017-01-17T22:03:08.334502Z K 7 svn:log V 440 Sync in the latest CloudABI generated source files. Languages like C++17 and Go provide direct support for slice types: pointer/length pairs. The CloudABI generator now has more complete for this, meaning that for the C binding, pointer/length pairs now use an automatic naming scheme of ${name} and ${name}_len. Apart from this change and some reformatting, the ABI definitions are identical. Binary compatibility is preserved entirely. END
