[httpc] httpc manager crashes. + When a request results in a retry, the request id will be "reused" + in the previous implementation a race condition could occur causing + the manager to crash.

[httpc] Issuing a request (httpc:request) to an + host with the ssl option + {ip, {127,0,0,1}} results in an handler crash. + The reason was that the connect call resulted in an exit with + reason badarg + (this was the same for both ssl and gen_tcp).

+

Exits was not catched. This has now been improved.
