tests/servers: use our platform-aware pid for server verification

The pid used for server verification is later stored as pid2 in
the hash of running test servers and therefore used for shutdown.

The pid used for shutdown must be the platform-aware (Win32) pid
to avoid leaking test servers while running them using Cygwin/msys.

cmake: fix support for UnixSockets feature on Win32

Move the definition of sockaddr_un struct from config-win32.h to
curl_setup.h, so that it could be shared by all build systems.

Add ADDRESS_FAMILY typedef for old mingw, now old mingw can also use
unix sockets.

Also fix the build of tests/server/sws.c on Win32 when USE_UNIX_SOCKETS
is defined.

tests: introduce preprocessed test cases

The runtests script now always performs variable replacement on the
entire test source file before the test gets executed, and saves the
updated version in a temporary file (log/test[num]) so that all test
case readers/servers can use that version (if present) and thus enjoy
the powers of test case variable substitution.

This is necessary to allow complete port number freedom.

Test 309 is updated to work with a non-fixed port number thanks to this.

silly web server: silent a compilation warning

Recent gcc warns when byte count of strncpy() equals the destination
buffer size. Since the destination buffer is previously cleared and
the source string is always shorter, reducing the byte count by one
silents the warning without affecting the result.

http: added 417 response treatment

When doing a request with a body + Expect: 100-continue and the server
responds with a 417, the same request will be retried immediately
without the Expect: header.

Added test 357 to verify.

Also added a control instruction to tell the sws test server to not read
the request body if Expect: is present, which the new test 357 uses.
