* internal.h (WARN_UNUSED_RESULT): moved to configure.in, to
actually check its availability rather to check GCC's version.
* configure.in (WARN_UNUSED_RESULT): moved to here.
* configure.in (RUBY_FUNC_ATTRIBUTE): change function declaration
to return int rather than void, because it makes no sense for a
warn_unused_result attributed function to return void.
Funny thing however is that it also makes no sense for noreturn
attributed function to return int. So there is a fundamental
conflict between them. While I tested this, I confirmed both
GCC 6 and Clang 3.8 prefers int over void to correctly detect
necessary attributes under this setup. Maybe subject to change
in future.
* internal.h (UNINITIALIZED_VAR): renamed to MAYBE_UNUSED, then
moved to configure.in for the same reason we move
WARN_UNUSED_RESULT.
* configure.in (MAYBE_UNUSED): moved to here.
* internal.h (__has_attribute): deleted, because it has no use now.
* string.c (rb_str_enumerate_lines): refactor macro rename.
* string.c (rb_str_enumerate_bytes): ditto.
* string.c (rb_str_enumerate_chars): ditto.
* string.c (rb_str_enumerate_codepoints): ditto.
* thread.c (do_select): ditto.
* vm_backtrace.c (rb_debug_inspector_open): ditto.
* vsnprintf.c (BSD_vfprintf): ditto.
