- only include openssl if the openssl option is present
- include arpa/inet.h to get ntohl and friends on older platforms like
Interix
- use new netdb.h compat code from libnbcompat
- include inttypes.h only when present
- don't name local variables err, Interix has a symbol like that in
default namespace
- allow fetch_read to do short read and do more intelligent buffering
for header processing; effectively don't do a system call for each
byte read
Start URL quoting cleanup. All URLs are now quoted correctly on parsing
and when appending URLs. URLs without schema and starting with slash are
considered to be file:// URLs.
- remove most of the debug junk
- fix a buffer overflow in the config parser
- replace stdio usage with a simple abstract IO framework. currently
without explicit buffering, but that might be added later
