radiusclient thread-safety

[Alex Massover]

Hmmm.. Sorry again. This is not result of wrong configs. This is what I get when I do rc_handle per thread:

rc_handle *rh;
if ((rh = rc_read_config(RC_CONFIG_FILE)) == NULL) { ... }
if (rc_read_dictionary(rh, rc_conf_str(rh, "dictionary")) != 0) {...}
[...build send avpair...]
rc_auth();

If I have a static rc_handle and call rc_read_config() and rc_read_dictionary() in parent there's no such problem.

I'm even able to call rc_avpiar_log() just before rc_auth() and get correct dump of my avpiar.
