  larger than 1024 bytes.

  instead of being repeated several times. This also include Authenticate: and
  Proxy-Authenticate: headers and while this hardly every happens in real life
  it will confuse libcurl which does not properly support it for all headers -
  like those Authenticate headers.

Fix 'uploaded' file descriptor leak

signal handling to cleanup on SIGINT and SIGTERM

  curl_easy_setopt with CURLOPT_HTTPHEADER, the library should set
  data->state.expect100header accordingly - the current code (in 7.19.7 at
  least) doesn't handle this properly. Martin Storsjo provided the fix!

- In order to better reflect that the returned pid is extracted from the
  given file, serverpid sub is renamed to pidfromfile. In addition it is
  enhanced to make sure that it always returns zero unless a numerical
  positive value is returned.

- To better reflect that only process existance is actually checked,
  checkserver sub is renamed to processexists. In addition it is enhanced
  making it remove the given pid file when the extracted pid is no longer
  alive.

have been fixed!

- Added Diffie-Hellman parameters to several test harness certificate files in
  PEM format. Required by several stunnel versions used by our test harness.

Use different log files for each protocol

Fix compiler warning: unused variable `data'

  rework patch that now integrates TFTP properly into libcurl so that it can
  be used non-blocking with the multi interface and more. BLKSIZE also works.

  The --tftp-blksize option was added to allow setting the TFTP BLKSIZE from
  the command line.

Set 0600 file permissions on certificate pem files.

   meter/callback during FTP command/response sequences. It turned out it was
   really lame before and now the progress meter SHOULD get called at least
   once per second.

  which might contain non-SRV answers, skipping over potential non-SRV
  ones such as CNAMEs.

  finer granularity control when generating src and lib makefiles.

Fix compiler warning: conditional expression is constant.

  though it failed to write a very small download to disk (done in a single
  fwrite call). It turned out to be because fwrite() returned success, but
  there was insufficient error-checking for the fclose() call which tricked
  curl to believe things were fine.
