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...
(c_cpp_diagnostic): ...this, converting level and reason to enums.
* c-opts.c (c_common_init_options): Update for renaming.
gcc/fortran/ChangeLog:
* cpp.c (gfc_cpp_init_0): Update for renamings.
(cb_cpp_error): Rename to...

Update for renaming of...
(selftest::ebcdic_execution_charset::on_error): ...this, renaming

"m_errors" to "m_diagnostics".
(selftest::lexer_test_options::apply): Update for renaming of...
(selftest::lexer_test_options::on_error): ...this, renaming to...
(selftest::lexer_test_options::on_diagnostic): ...this
converting level and reason to enums.
(selftest::test_lexer_string_locations_raw_string_unterminated):
Update for renamings.

"reason".
libcpp/ChangeLog:
