URLs ending with a slash properly (it should list the contents of that
directory). Test case 351 brought back and also test 1010 was added.

several functions (write_tcp_data, read_tcp_data, read_udp_packets) so that
if it fails and the socket is closed the following code doesn't try to use
the file descriptor.

TCP is used since there are several edge cases where it still makes sense.

something with the ares_save_options() where it would try to do a malloc(0)
when no options of that type needed to be saved.  On most platforms, this was
fine because malloc(0) doesn't actually return NULL, but on AIX it does, so
ares_save_options would return ARES_ENOMEM.

the --proxy-negotiate command line option to allow a user to explicitly
select it.

Made a few more tests work remotely.

o It looks for the NSS database first in the environment variable SSL_DIR,
  then in /etc/pki/nssdb, then it initializes with no database if neither of
  those exist.

o If the NSS PKCS#11 libnspsem.so driver is available then PEM files may be
  loaded, including the ca-bundle. If it is not available then only
  certificates already in the NSS database are used.

o Tries to detect whether a file or nickname is being passed in so the right
  thing is done

o Added a bit of code to make the output more like the OpenSSL module,
  including displaying the certificate information when connecting in
  verbose mode

o Improved handling of certificate errors (expired, untrusted, etc)

The libnsspem.so PKCS#11 module is currently only available in Fedora
8/rawhide. Work will be done soon to upstream it. The NSS module will work
with or without it, all that changes is the source of the certificates and
keys.

key was specified and there was no HOME environment variable, and then it
didn't continue to try the other auth methods. Now it will instead try to
get the files id_dsa.pub and id_dsa from the current directory if none of
the two conditions were met.

sent by curl, if not the addresses themselves.

Added hooks to the test suite to make it possible to test a curl running
on a remote host.

instead of hard-coding it to 127.0.0.1

proxies for FTP urls.

fixed some AC_SUBST configure entries.

Removed and fixed some AC_SUBST configure entries.
