Compiler messaging mega patch.
va_yyreport() is now the main C-level dispatcher for compiler messages.
It also handles the automatic conversion of type errors to warnings in compat mode.
Consolidated the location for the implementation of most of the yy*-messaging functions to program.c.
Added yytype_report().
Changed APIs for yyexplain_*().
Moved the definitions of REPORT_* from pike_compiler.h to program.h.
va_yyerror() and low_yyerror() are no more.
Most type-system messages should now be marked with the appropriate subsystem.
Reenabled the typechecking for sscanf and sprintf() now that errors are converted into warnings in compat mode.
