Needed elsewhere too?

the multi interface

  app to retrieve the errno variable after a (connect) failure. It will make
  sense to provide this for more failures in a more generic way, but let's
  start like this.

by Gisle Vanem's patch, only modified by me.

generic connect uses

that resolves to multiple IP addresses.

linked list for name resolved data, even on hosts/systems with only IPv4
stacks as this simplifies a lot of code.

status more obvious

actually known, as before this text lied when used in i.e FTP.

a host name that resolves to multiple IP addresses.

we now use it to provide more info back on connect failures.

memory.h is included everywhere for this.

all things up to work with encoded host names internally, as well as keeping
'display names' to show in debug messages. IDN resolves work for me now using
ipv6, ipv4 and ares resolving. Even cookies on IDN sites seem to do right.

make the code easier to read

sessionhandle to make the duphandle() function work as supposed. Also tried
to start document functions the doxygen way (in the headers of the functions).
Can't make it work though...
