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

s/socklen_t/curl_socklen_t/g

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.

  CARES_HAVE_ARES_FREE_DATA. Current functionality of ares_free_data()
  makes it unnecessary.

  ares_addr6ttl in order to prevent name space pollution, along with
  necessary changes to code base and man pages.This change does not break
  ABI, there is no need to recompile existing applications. But existing
  applications using these structs with the old name will need source code
  adjustments when recompiled using c-ares 1.6.1.

  with the ones declared in ares.h

Make configure remove the curlbuild.h file included in distribution tarballs
for use by non-configure systems. As intended, configure would overwrite the
distributed one when doing in-tree builds. But VPATH builds would end having
two curlbuild.h files, one in the source tree and another in the build tree.

Make configure remove the ares_build.h file included in distribution tarballs.

Fix macro redefinition.

Fix name space pollution.
