### Description
Current `parser_fline.c` is not supports HTTP/2 protocol and generates errors like below
This is happens because
[`HTTP_VERSION`](https://github.com/kamailio/kamailio/blob/cfc89db53c087382c29d809dc0bc56f7351af2d1/src/core/parser/parse_fline.c#L102)
macro designed to work only with
[`HTTP/1.x`](https://github.com/kamailio/kamailio/blob/cfc89db53c087382c29d809dc0bc56f7351af2d1/src/core/parser/parse_fline.h#L49)
protocol.
### Expected behavior
Response from `HTTP/2` enabled server is parsed without error.
#### Actual observed behavior
```
246(251) ERROR: <core> [core/parser/parse_fline.c:257]: parse_first_line():
parse_first_line: bad message (offset: 11)
246(251) ERROR: <core> [core/parser/msg_parser.c:675]: parse_msg(): ERROR:
