Fixed Clippy warnings
Fixed “myvar” test failures - related to base_env() being the “local” enviroment in the tests.
Fixes for builds on ARM and PPC platforms.
Converted R! to a procedural macro, allowing parameters.
Converted pairlist! to a procedural macro.
Remove unused lazy_static
Continued improvments to wrappers for specific R types such as environments, functions and symbols.
Install system dependencies on Linux.
Use Use failure() to trigger steps on failures
SymPair::sym_pair() now returns
Added contributing guidelines and code of conduct.
Made use of ndarray optional.
Made #[extendr] calls panic and thread safe.
Added NA handling to the #[extendr] macro.
Added a separate extendr-engine crate that is needed when calling R from Rust.

Optional parameters to support NA handing.
Errors thrown if input parameters without Option are NA.
Harmonising of function names into integer, real, logical, symbol, raw, list, pairlist and env.
