Overhaul file and buffer operation #170

Closed k0ekk0ek closed 5 months ago

k0ekk0ek commented 5 months ago

Add buffer limit to avoid hogging all memory on malicious inputs.
Drop use of PathIsRelative to remove dependency on shlwapi.
Always allocate size+padding.
Log an error if $INCLUDE is unsuccessful.

Now also requires at least on RR owner before RRs starting with <blank> are allowed. Also, add include_limit to zone_options_t to limit the maximum number of includes. Default is 10.
