unsafe_op_in_unsafe_fn: ld_so, generic/redox-rt
...
There are a few functions where I allowed the lint. The lower level and
FFI nature of relibc means that there are areas with a lot of unsafe.
Some functions are basically long blocks of unsafe or contain lots of
small blocks of unsafe. unsafe_op_in_unsafe_fn doesn't add clarity to
these functions. Instead, it reduces readability by adding an indent or
small "unsafe { .. }" clutter.

fix(ld.so): errors UB
...
Currently, how ld.so errors are handled by functions in dlfcn is wrong.
dlopen calls `linker.load_library` which returns a
`Result<ObjectHandler, goblin::Error>`. Now `goblin::Error` may have
variants that are heap allocated. For example:
`Error::Malformed(format!("invalid path: '{}': {}", path, err))`. The
error string would be allocated by ld.so's allocator but will be dropped
inside libc. This is UB.
After this patch, we now return a custom `DlError` instead. To get more
information about the error, `LD_DEBUG=all` can be set.
