Revert all changes to dln.c, dmydln.c, dln.h for the shared GC

Allow RUBY_GC_LIBRARY_PATH to be set in miniruby

2024-04-26T21:02:08+00:00

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.

Pass string error buffer into dln_open

2024-04-24T17:10:06+00:00

On Windows, the error exists on the stack so we should pass an error
buffer from the caller.

Get error from dln_open when USE_SHARED_GC

2024-04-23T19:29:42+00:00

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.

Split `init_funcname`

2024-02-22T06:43:46+00:00

Extract `build_funcname` that takes the prefix as an argument, and
`concat_funcname` that concats the parts.

Do not define ABI version in statically linked objects

It is for dynamically loading, useless for statically linked objects.
