and merge when new names are added

It now properly handles code that uses curl_free() (since not all versions of
curl have it), and also fixes a few problems when detecting libcurl on MinGW,
and a linker problem on OSX Panther.

1) findtool does look per tool in PATH and think ./perl is the perl
executable, while is just a local directory (I have . in the PATH)

2) I got several warning for head -1 deprecated in favour of head -n 1

3) ares directory is missing some file (missing is missing :-) ) because
automake and friends is not run.

(Let's hope number 2 doesn't break somewhere "out there", if so we can always
search/replace that back.)

from 2003 and added all names from all release notes in the CVS (there is a
slight gap though). I removed names with only first names (Like "Chris" and
"Ralph") , as that won't make anyone happy and we might list their full names
as well anyway.

This list is now intended to include _all_ people that contribute: big or
small. 389 names at the time of this commit.

least it should no longer cause a compiler error. However, it does not have
AI_NUMERICHOST so we cannot getaddrinfo() any numerical addresses with it (we
use that for FTP PORT/EPRT)! So, I modified the configure check that checks if

AIX 4.3 and it will automatically build with IPv6 support disabled.

--trace, --trace-ascii and --verbose output. I also made the '>' display
separate each line on the linefeed so that HTTP requests etc look nicer in the
-v output.
