CURLOPT_NOBODY enabled but not CURLOPT_HEADER, libcurl wouldn't do TYPE
before it does SIZE which makes it less useful. I walked over the code and
made it do this properly, and added test case 542 to verify it.

directory). Test case 351 brought back and also test 1010 was added.

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.

  this fix.

Renamed the curl_ftpssl enum to curl_usessl and its enumerated constants,
creating macros for backward compatibility.

and allow reuse by multiple protocols. Several unused error codes were
removed.  In all cases, macros were added to preserve source (and binary)
compatibility with the old names.  These macros are subject to removal at
a future date, but probably not before 2009.  An application can be
tested to see if it is using any obsolete code by compiling it with the
CURL_NO_OLDIES macro defined.

out that libcurl didn't deal with large responses from server commands, when
the single response was consisting of multiple lines but of a total size of
16KB or more. Dan Fandrich improved the ftp test script and provided test
case 1006 to repeat the problem, and I fixed the code to make sure this new
test case runs fine.

out that doing first a file:// upload and then an FTP upload crashed libcurl
or at best caused furious valgrind complaints. Fixed now by making sure we
free and clear the file-specific struct properly when done with it.

out that libcurl didn't deal with very long (>16K) FTP server response lines
properly. Starting now, libcurl will chop them off (thus the client app will
not get the full line) but survive and deal with them fine otherwise. Test
case 1003 was added to verify this.
