avoid the sensitive word as it looks bad in some people's eyes

only define _REENTRANT if not already defined, and only in setup.h

Updated the copyright year since changes have been this year.

use Curl_inet_pton(), not inet_pton().

- Tru64 and some IRIX boxes seem to not like test 237 as it is. Their
inet_addr() functions seems to use &255 on all numericals in a ipv4 dotted
address which makes a different failure...

- Tru64 and some IRIX boxes seem to not like test 237 as it is. Their
inet_addr() functions seems to use &255 on all numericals in a ipv4 dotted
address which makes a different failure... Now I've modified the ipv4
resolve code to use inet_pton() instead in an attempt to make these systems
better detect this as a bad IP address rather than creating a toally bogus
address that is then passed on and used.

avoid warnings on systems with this member set const

removed tabs and trailing whitespace from source

simplified the check for when to free() the buf data

Gisle fixed a bad free from the resolve reorg, I changed type of the buf
variable to sort out some compiler warnings.

ah, simplified my latest change more

fix for systems without gethostbyname_r()

made the Curl_he2ai() take the port number as an int intead, to avoid lots
of typecasts all over

use Curl_addrinfo, not 'struct addrinfo'

Source cleanups. The major one being that we now _always_ use a Curl_addrinfo
linked list for name resolved data, even on hosts/systems with only IPv4
stacks as this simplifies a lot of code.

curl_global_init_mem() allows the memory functions to be replaced.
memory.h is included everywhere for this.

Curl_ip2addr() now takes an in_addr_t argument instead to prevent compiler
warnings

Major hostip.c cleanup and split into multiple files and easier #ifdef
usage.
