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...

less

Curl_strerror() that attempts to be thread-safe _and_ works on Windows too!

defines are in setup.h.

because it is now possible to have both WIN32 and HAVE_CONFIG_H defined.

SO_BINDTODEVICE is present, to prevent compiler warnings about the variable

more" when the previous approach. Known to work on Linux, possibly on other
platforms as well.

2. now reads the socket error before check connect status, also to make us
   run fine on MPE/iX

warnings. Minor edits by me.
