ca074ce387 Write conversion from script and region to charmap
The generation tool creates a GetCharmap function in C which takes the
script and region as input and returns the charmap index.

e901b5baaa Parse script and region constants as numbers
This simplifies code generation, since we don't have to worry about what
happens if two symbolic constants have the same value.

db4187b65b Refactor table generator, handle line breaks
Extract table generation to its own file, table.go, and refactor the
interface. This exposed an inconsistency in the way that line breaks
were handled: both CR and LF on the Mac side were mapped to LF on the
UTF-8 side, but when the conversion table was inverted, the reverse
mappings would conflict. Previously, there was no explicit handling for
it, and whichever Mac charecter had a higher byte value would take
precedence. Conflicts are now detected and return an error, so line
breaks must be mapped explicitly. The new code maps CR, LF, and CRLF to
CR when converting UTF-8 to Mac.
