Add constants and string literals to funC

Browse source 
* Add special string literals "..."? (s,a,u,h,)

* Add string literal H (256-bit hash)

* Add string literal c (crc32)

* Use td::hex_encode instead of homebrew function and add test

* Fix error codes and use more generic address

* Add support for int and slice constants

* Add support for strongly typed constants

* Add support for precompiled constant expressions (hard!)
