Temporary hack to migrate functions to package kotlin.jvm.functions

Add a file in package 'kotlin.jvm.functions' to the project and replace
explicit imports of functions 'kotlin.Function{n}' to two imports 'kotlin.*'
and 'kotlin.jvm.functions.*', so that the codebase can be compiled both by the
old and by the new compiler
