ld.so: Support moving versioned symbols between sonames [BZ #24741]
This change should be fully backwards-compatible because the old code aborted the load if a soname mismatch was encountered (instead of searching further for a matching symbol). This means that no different symbols are found. The soname check was explicitly disabled for the skip_map != NULL case. However, this only happens with dl(v)sym and RTLD_NEXT, and those lookups do not come with a verneed entry that could be used for the check. The error check was already explicitly disabled for the skip_map != NULL case, that is, when dl(v)sym was called with RTLD_NEXT. But _dl_vsym always sets filename in the struct r_found_version argument to NULL, so the check was not active anyway. This means that symbol lookup results for the skip_map != NULL case do not change, either.
