Remove `ast::pure_fn` and all concept of `pure` from the compiler
replaced some 'std::' with 'extra::' in comments
Cleaned up middle a bit.

The only really tricky change is that a long chain of ifs, and elses
was turned into a single if, and a match in astencode.rs. Some methods
can only be called in certain cases, and so have to come after the if.

rustpkg: Begin allowing package scripts to call the default build logic

rustpkg/api.rs provides functions intended for package scripts to call.
It will probably need more functionality added to it later, but this is
a start.

Added a test case checking that a package script can use the API.

Closes #6401
