Remove the dynamic registration of result codes. Convert isc_result_t
from unsigned + #defines into 32-bit enum type in grand unified
<isc/result.h> header. Keep the existing values of the result codes
even at the expense of the description and identifier tables being
unnecessary large.
Additionally, add couple of:
switch (result) {
[...]
default:
break;
}
statements where compiler now complains about missing enum values in the
switch statement.
The dns_message_create() function cannot soft fail (as all memory
allocations either succeed or cause abort), so we change the function to
return void and cleanup the calls.
Previously, the bin/system/wire_test.c was optionally used as a fuzzer,
this commit extracts the parts relevant to the fuzzing into a
specialized fuzzer that can be used in oss-fuzz project.
The fuzzer parses the input as UDP DNS message, then prints parsed DNS
message, then renders the DNS message and then prints the rendered DNS
message. No part of the code should cause a assertion failure.
