testzzuf: re-worked zzuf testing

* merged test_get, test_get_chunked, test_put
* fixed use of header instead of footer in chunked data callback
* added checks for results of all used MHD functions
* added reading of all data in the input buffer provided by MHD for
  callback
* re-used libcurl handles to re-use connections in all modes
* added testing of 'poll' and 'epoll' for all tests
* removed the need for socat
* removed forking with potential forked process zombies
* fixed processing only of the first request (as soon  as socat
  connection become broken, all following requests went to nowhere)
* implemented correct response for unsupported methods
* used proper timeout for 'external select()' (taken into account
  libcurl timeout too)
* added check for extra reply data
* added debug print of libcurl sent and received data
* merged all tests into single source file
* fixed a lot of compiler warnings
* added check for incorrect replies produced by MHD
