Make HEP capture buffer size configurable via "bufsize="#320
Merged
Conversation
The per-message HEP capture buffer was hardcoded to 16000 bytes in both the HEPv2 and HEPv3 builders, capping how much of a SIP message could be captured with no way to raise it. Add a `bufsize=` parameter to the HEP capture URI, stored on the transport master as `mr_capt_bufsize`. Both builders read the cap from the master; when `bufsize=` is omitted it defaults to `TPORT_CAPT_BUFSIZE_DEFAULT` (16000), preserving prior behavior. Accepted range is [2048, 65000] (the HEPv3 envelope length is a u16). Example: `udp:host:9060;hep=3;bufsize=32768`
