Redirect ssh output to ssh.log

- -s/--silent can now be used to toggle off the silence again if used a second
  time.

- Added Daniel Black's work that adds the first few SOCKS test cases. I also
  fixed two minor SOCKS problems to make the test cases run fine.

Added more options to the ssh config file to improve the consistency of
the test environment.
Force a rewrite of the ssh config files on every invocation.
Changed the opens to work on older versions of perl.

to do nonlistening server tests, like other tests.

to find that it crashed miserably, and this was due to some select()isms left
in the code. This was due to API restrictions in c-ares 1.3.x, but with the
upcoming c-ares 1.4.0 this is no longer the case so now libcurl runs much
better with c-ares and the multi interface with > 1024 file descriptors in
use.

specific sockets and thus avoiding select() and associated functions/macros.
This function will be used by upcoming libcurl releases for this very
reason. It also made me export the ares_socket_t type in the public ares.h
header file, since ares_process_fd() uses that type for two of the arguments.

overwrite in Curl_select(). While fixing it, I also improved its performance
somewhat by changing calloc to malloc and breaking out of a loop earlier
(when possible).

I also switched from calloc() to malloc() as a minor performance boost since
the rest of the code fills in the structs fine anyway - and they must for the
case when we use the stack-based auto variable array instead of the allocated
one.

I made the loop filling in poll_fds[] break when poll_nfds is reached as a
minor speed improvement.

transfers are done and need to be removed and closed or re-added.

Black identifying several FTP-SSL test cases fail when we build libcurl with
NSS for TLS/SSL. Listed as #42 in KNOWN_BUGS.

that could cause it to return a bad return code.
