86f5742015 Add two implementations of getaddrinfo: one blocking and one nonblocking. 
The entry points are evutil_getaddrinfo and evdns_getaddrinfo respectively.
There are fairly extensive unit tests.

I believe this code conforms to RFC3493 pretty closely, but there are
probably more issues.  It should get tested on more platforms.

This code means we can dump the well-intentioned but weirdly-implemented
bufferevent_evdns and evutil_resolve code.

0b9eb1bffb Add a bufferevent function to resolve a name then connect to it. 
This function, bufferevent_socket_connect_hostname() can either use
evdns to do the resolve, or use a new function (evutil_resolve) that
uses getaddrinfo or gethostbyname, like http.c does now.

This function is meant to eventually replace the hostname resolution mess in
http.c.

b85b710cf5 Update copyright statements to reflect the facts that: 
a) this is 2009
b) niels and nick have been comaintainers for a while
c) saying "all rights reserved" when you then go on to explicitly
   disclaim some rights is sheer cargo-cultism.

Add an --enable-gcc-warnings option (lifted from Tor) to the configure script.  When provided, and when we are using GCC, we enable a bunch of extra GCC warnings in the compiler.  Also, make the code all build happily with these warnings.

In ANSI C, int func() is a function with unspecified arguments, whereas int func(void) is a function that takes no arguments.  Using int func() to mean a function with no arguments is a C++ism, so let's not use or generate it.
