returned an error as there might be stuff in there we must free/cleanup.
This fixes the memory leak Yanick Pelletier posted about 16 Oct 2001

now more accurate since it is based on actual spent time without the
assumptions from before

libcurl should use in its request

failf("%d") without the error as argument... it would always make a weird
number get output

same name as common functions...

the pack_hostent() is only compiled if gethostbyname_r() isn't present.

for when gethostbyname() is used so that we have the memory of the struct
allocated. This turns out to be needed if the curl handled is passed between
threads on Windows and possibly other operating systems where we use that
function.

is once again running OK

we check for the error state before believing we are connected in IPv6
cases

IPv6

changed the Curl_connethost() proto again

name resolving, as that should be the *ONLY* section in libcurl that may
take a while in a synchronous call.

valid time. we now store the filetime as a long to know for sure it can
hold -1 (there exist some unsigned time_t cases)
