This should make hash processing generally faster.
There is a treadeoff between memory footprint and
speed of processing. 10 KB instead of 1.2 KB of
hash table per process should not be a huge problem
even on very limited current systems.
Who really needs to stick to 32 buckets could
recompile. We could also think about making
this configurable at some point.

This hash function distributes much better than the
original one. The effect is not as visible with
hashes taken modulo 32 than with a bigger modulus,
but it is there. And larger number of buckets migh
become possible in the future...

Effectively, the return code of fcntl was not checked
by not checking the return code of socket_nonblocking()
for the server fd.

Use extract_url instead of the old extract_ssl_url:
extract_url is generic and handles ipv6 literal addresses correctly.

extract_url
There is in fact nothing http-specific any more about this function, hence
the rename. The input has been stripped of the <proto>:// header anyways.
This in preparation of fixing bug BB#106: ssl fails with literal ipv6 addrs.

When removing the '[' and ']' characers from the ipv6 literal address, make sure
the pointer that is later free'd stays a malloced pointer by memmoving the

config
This is achieved by not stopping at the first result of getaddrinfo
that we managed to listen on: Without "Listen" in the config, we
call getraddrinfo with NULL address. With AI_PASSIVE, this gives results
for both IPv4 and IPv6 wildcard addresses (if both are supported).
This lets tinyproxy listen on both IPv4 and IPv6 wildcard if the system
supports them.

This changes listen_sock() to not return the
addrlen of the used address from getaddrinfo call
to the caller, stored in global addrlen in child.c.
This was only used to be able to allocate enough space for the
arguments to the later accept call depending on whether
IPv4 or IPv6 is used.
This removes the need to pass this info by always allocating
sizeof(struct sockaddr_storage) instead, which is enough
to carry both sockaddr_in and sockaddr_in6.

Supplementary groups are inherited from the calling process. Drop all
supplementary groups if the "Group" configuration directive is set to
change to a different user. Otherwise the process may have more rights
than expected.
