BUG/MINOR: http: Missing calloc return value check in parse_http_req_capture
A memory allocation failure happening in parse_http_req_capture while
processing a "len" keyword and allocating a cap_hdr structure would
have resulted in a crash. This function is only called during
configuration parsing.
It was raised in GitHub issue #1233.
It could be backported to all stable branches.
