tint: introduce the new tint build system with checksum verification
Three stages of the new tint build system:
1) generate_core.sh extracts the core part from buildgcc script, most importantly the checksum calculation/verification functions.
2) tintify_core.sh adds the tint-specific footer/header to the core, such as the properties of current version including its checksum.
3) tint.sh - generated and "tintified" core script - builds a tint.
