Project specific settings now reside in config.mk; version info in version.mk

Updates to reflect last batch of changes

Optionally save away foreign decl .c stubs; added hooks to allow compilation results to be UDPed back to HQ

Painfully desugaring foreign decls

Front end changes to handle foreign declarations

Updates to reflect changes elsewhere

Warn if folded Int primops cause overflows

okToUnfoldPrimOp: CCallOp update

StCall now takes extra callconv arg; StixPrim.primCode doesn't flush stdout and stderr anymore (it's done in the .hc code)

Check type variable scoping (code currently not enabled);

Word* and Int*  tycons added to data_tycons

Needed to snaffle bits and pieces out of Int and Word, so add

Added Int64Rep and Word64Rep. new funs: is64BitRep, showPrimRepToUser, getPrimRepSizeInBytes

getPrimRepInfo: deal with 64-bit reps

New primitive types; new functions: isFFIExternalTy, isFFIResultTy, isFFIArgumentTy

LongReg updates

Added LongRegs to MagicIds

The project version is now set via command-line opt

New const: mAX_Long_REG

New options: -ddump-foreign-stubs, -femit-extern-decls, opts for output files for foreign decl stubbery, (the oh-so cool) -freport-compile, -fhi-version
