Do not zero-fill newly allocated files on Windows

On Windows platforms code was added to zero-fill each newly allocated data file in order to work around Windows KB http://support.microsoft.com/kb/2731284. The KB only applies for Windows 7 and Windows 2008 Server installations, so there is no need to do it on each and every system.

This fix restricts the zeroing-out code to only versions, which have had the bug. It will not check whether the hot fix has been installed.
SERVER-12383 Add upper bound for userCacheInvalidationInterval
SERVER-10906 StageBuilder set $language correctly for STAGE_TEXT

The type of expression on the right side of the assignment is
std::string.  Hence, 'language' was set to point inside a temporary
std::string constructed to hold the data from the result of c_str(),
instead of being set to point inside the the result of str() (which
has static lifetime).  Hence, 'language' became a dangling pointer.
