Added missing tests in CMake, added Makefile.inc for tests (+ use in CMake scripts), and fixed a missing define under windows in a test source file.

  and 1 on fatal errors. Previously it only mentioned non-zero on fatal
  errors. This is a slight change in meaning, but it follows what we've done
  elsewhere before and it opens up for LOTS of more useful return codes
  whenever we can think of them...

PS: Once again, sorry if the added files have executable perms on Linux.

PS: Sorry if the added file has executable perms on Linux, I didn't found anything related to it...

Removed the "lib" prefix under linux ("was "liblibcurl") and fixed import library name under Win32 (Added "_imp" for dynamically linked).

non-configured libcurl. In this case curl_off_t data type was gated
to the off_t data type which depends on the _FILE_OFFSET_BITS. This
configuration is exactly the unwanted configuration for our curl_off_t
data type which must not depend on such setting. This breaks ABI for
libcurl libraries built with Sun compilers which were built without
having run the configure script with _FILE_OFFSET_BITS different than
64 and using the ILP32 data model.

Initial CMake scripts (libcurl only), based on the merge of tetest scripts and mine. These are far to be functionnal yet.
PS: Hello world :)

  strdup() call failed.

functions if the easy handles are used in multiple threads

  NSS is used. These ciphers were added in NSS 3.4 and require to be enabled
  explicitly.

If CURL_DISABLE_PROXY is defined, we must allow socks_sspi.c to call
Curl_blockread_all(). It is needed in code inside USE_WINDOWS_SSPI.

  library is found to support it.

catch them all. The memory debug stuff is not in the public API anyway.
