added support for new SQLite cert database format: added a runtime check for version 3.12.0, and depending on the result add 'sql:' prefix to cert database directory so that newer SQLIte database format works.

added aditional check for the directory specified with SSL_DIR, and fall back to hardcoded directory if not a valid directory.

fix compiler warning: comparison between signed and unsigned

into curl_rand.c and curl_rand.h

  powered libcurl in 7.19.6. If there was a X509v3 Subject Alternative Name
  field in the certficate it had to match and so even if non-DNS and non-IP
  entry was present it caused the verification to fail.

statically linking since libssh2 needs the SSL library link flags to be
set up already to satisfy its dependencies. This wouldn't be necessary
if the libssh2 configure check was changed to use pkg-config since the
--static flag would add the dependencies automatically.

POLLIN, and sets POLLERR without setting POLLIN and POLLOUT. In some
libcurl code execution paths this could trigger busy wait loops with
high CPU usage until a timeout condition aborted the loop.

This fix for Curl_poll adresses the above in a libcurl-wide mode.

Some systems poll function sets POLLHUP in revents without setting
POLLIN, and sets POLLERR without setting POLLIN and POLLOUT. In some
libcurl code execution paths this could trigger busy wait loops with
high CPU usage until a timeout condition aborted the loop.

The reverted patch addressed the above issue for a very specific case,
when awaiting c-ares to resolve. A libcurl-wide fix superceeds this one.

libcurl tests.

 This fixes a loop problem with high CPU usage.

  start second "Thu Jan 1 00:00:00 GMT 1970" as the date parser then returns 0
  which internally then is treated as a session cookie. That particular date
  is now made to get the value of 1.

changed NetWare makefiles to rely on SHELL rather than OSTYPE since we can have a sh-like shell also on Windows (MSYS, Cygwin).

done!
