Cleanup of libcpp diagnostic callbacks
This patch renames the "error" callback within libcpp to "diagnostic", and uses the pair of enums in cpplib.h, rather than passing two different kinds of "int" around. gcc/c-family/ChangeLog: * c-common.c (c_option_controlling_cpp_error): Rename to... (c_option_controlling_cpp_diagnostic): ...this, and convert "reason" from int to enum. (c_cpp_error): Rename to... (c_cpp_diagnostic): ...this, converting level and reason to enums. * c-common.h (c_cpp_error): Rename to...
