Fix libtests test suites to pass on Windows, mostly by dealing with ascii vs. binary and NL vs. CRNL change ($td->NORMALIZE_NEWLINES). Convert some test suites to use fread instead of read. PCRE.hh: define PCRE_STATIC if on Windows. Provide cross-platform function for getting current time instead of using time(0). git-svn-id: svn+q:///qpdf/trunk@678 71b93d88-0707-0410-a8cf-f5a4172ac649
