[wasm] dln.c: Guard `dladdr` use in symbol incompatibility check

2023-12-19T02:13:38+00:00

wasi-libc recently added a family of `dl*` functions[^1], but it still
doesn't have `dladdr` unlike other platforms. Guard the use of `dladdr`
with `HAVE_DLADDR` to avoid build failure with the head version of
wasi-libc.
The library name is used only for diagnostic purpose if it's not NULL,
so it's safe to skip it.

rb_ext_resolve_symbol: C API to resolve and return externed symbols [Feature #20005]

2023-12-14T08:39:42+00:00

This is a C API for extensions to resolve and get function symbols of other extensions.
Extensions can check the expected symbol is correctly loaded and accessible, and
use it if it is available.
Otherwise, extensions can raise their own error to guide users to setup their
environments correctly and what's missing.

dln_symbol: make dln_sym accessible Ruby internally

2023-12-14T08:39:42+00:00

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.

Update dln.c to fix error output from `dln_open()`

2023-03-21T10:10:19+00:00

`libruby_name` gets trashed by `dlclose(handle)`, so output the
"linked to incompatible ... " error before calling `dlclose(handle)`.
