added some missing items

- Michael Wallner provided a patch that allows "SESS" to be set with

  CURLOPT_COOKIELIST, which then makes all session cookies get cleared.

- Tor Arntsen made test 271 run fine again since the TFTP path fix.

Daniel (23 May 2006)

- Martin Michlmayr filed debian bug report #367954, but the same error also

  showed up in the autobuilds. It seems a rather long-since introduced shell

  script flaw in the configure script suddenly was detected by the bash

  version in Debian Unstable. It had previously passed undetected by all

  shells used so far...

- David McCreedy updated lib/config-tpf.h

Daniel (11 May 2006)

- Fixed the configure's check for old-style SSLeay headers since I fell over a

  case with a duplicate file name (a krb4 implementation with an err.h

  file). I converted the check to manually make sure three of the headers are

  present before considering them fine.

- David McCreedy provided a fix for CURLINFO_LASTSOCKET that does extended

  checks on the to-be-returned socket to make sure it truly seems to be alive

  and well. For SSL connection it (only) uses OpenSSL functions.
