memdebug build, 'make' no longer builds the demo tools

'make all' also builds the demos

include ares_private.h to make sure we get the memdebug stuff included

If CURLDEBUG is set we use the libcurl internal memdebug system to track
memory leaks etc.

only build adig and ahost if 'make demos' is used

support closesocket() for closing sockets as well, as then we can use this
code fine on ares!

Make realloc() support NULL as pointer. Made to allow us to use these routines
to memdebug the ares stuff as well.

item 24 fixed, edited a few issues

Make the 'areschannel' get created in the curl_easy_init() and re-use that
same channel during the whole curl handle's life until curl_easy_cleanup().

Jeff Lawson pointed out that we need to check for a '5' in the version field
to properly work with SOCKS5 proxies. I also included some ascii art describing
the SOCKS5 response, as RFC1928 describes. Jeff provided details in bug

Andr�s Garc�a added a check for lwinmm for Mingw/sys

Mark the dns entry 'inuse' properly even when used from the cache. This
seems to correct some host cache screw-ups I could reproduce.

another case which should use CURLcode and not int

Use the was_iface variable when binding a socket locally, even if no
SO_BINDTODEVICE is present, to prevent compiler warnings about the variable

(void) functions we don't check the return code for

CURLcode/int cleanup to reduce IRIX warnings
Removed some dates/names in the comments.

spell!

don't assume we can use gcc 2.96+ options

in the socks code, make sure we receive Curl_read results in ints and
Curl_write in CURLcode, to keep the picky compilers happy
