common: Replace macro based function calls by using DEFAULT_ERRSOURCE.

Browse Source 
* common/dns-cert.h (get_dns_cert): Remove macro.
* common/dns-cert.c (_get_dns_cert): Rename to get_dns_cert.  Replace
arg ERRSOURCE by global DEFAULT_ERRSOURCE.
* common/http.h (http_parse_uri, http_raw_connect, http_open)
(http_open_document, http_wait_response): Remove macros.
* common/http.c (_http_parse_uri, _http_raw_connect, _http_open)
(_http_open_document, _http_wait_response): Remove underscore from
symbols.  Replace args ERRSOURCE by global DEFAULT_ERRSOURCE.
* common/ssh-utils.h (ssh_get_fingerprint)
(ssh_get_fingerprint_string): Remove macros.
* common/ssh-utils.h (_ssh_get_fingerprint)
(_ssh_get_fingerprint_string): Remove underscore from symbols.
Replace args ERRSOURCE by global DEFAULT_ERRSOURCE.
* common/tlv.h (parse_ber_header, parse_sexp): Remove macros.
* common/tlv.c: Include util.h.
(_parse_ber_header, _parse_sexp): Remove underscore from symbols.
Replace args ERRSOURCE by global DEFAULT_ERRSOURCE.
