miniruby is used by tool/runruby.rb, so we need to ensure we don't rb_bug
when RUBY_GC_LIBRARY_PATH is set so we can run tests using the make
commands. This commit changes it to warn instead.
Before, if dln_open failed to open RUBY_GC_LIBRARY_PATH, it would segfault
because it would try to raise an error, which cannot happen because the
GC has not been initialized yet.
This commit changes dln_open to return the error that occurred so the
caller can handle the error.
The symbol resolved by dln_symbol will eventually be passed to
extensions. The error handling of dln_sym is also separated into
dln_sym_func because the new call resolving symbols will not raise
LoadError.
According to MSVC manual (*1), cl.exe can skip including a header file
when that:
- contains #pragma once, or
- starts with #ifndef, or
- starts with #if ! defined.
GCC has a similar trick (*2), but it acts more stricter (e. g. there
must be _no tokens_ outside of #ifndef...#endif).
Sun C lacked #pragma once for a looong time. Oracle Developer Studio
12.5 finally implemented it, but we cannot assume such recent version.
This changeset modifies header files so that each of them include
strictly one #ifndef...#endif. I believe this is the most portable way
to trigger compiler optimizations. [Bug #16770]

Saves comitters' daily life by avoid #include-ing everything from
internal.h to make each file do so instead. This would significantly
speed up incremental builds.
We take the following inclusion order in this changeset:
1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very
first thing among everything).
2. RUBY_EXTCONF_H if any.
3. Standard C headers, sorted alphabetically.
4. Other system headers, maybe guarded by #ifdef
5. Everything else, sorted alphabetically.
Exceptions are those win32-related headers, which tend not be self-
containing (headers have inclusion order dependencies).
* eval.c (set_method_visibility): should have clear cache forq
updated visibility.
* numeric.c (flo_to_s): default format precision to be "%.16g".
* util.c (ruby_strtod): use own strtod(3) implementation to avoid
locale hell. Due to this change "0xff".to_f no longer returns 255.0
* eval.c (avalue_to_yvalue): new function to distinguish yvalue
(no-arg == Qundef) from svalue (no-arg == Qnil).
* eval.c (rb_yield_0): use avalue_to_yvalue().
* eval.c (assign): warn if val == Qundef where it means rhs is
void (e.g. yield without value or call without argument).
* parse.y (value_expr): need not to warn for WHILE and UNTIL,
since they can have return value (via valued break).

types (except long long such as dev_t).
* eval.c (rb_mod_nesting): should not push nil for nesting array.

rb_mod_const_at() for nil (happens for singleton class).

itself, no longer use rb_iv_set() to avoid freeze check error.
