  Add test-suite coverage testing using gcov Add a new "coverage" Makefile target that re-builds the library and tests using the gcc compiler/linker flags required by gcov, runs the test suite to capture the runtime data, then compiles a coverage report. The report, which is saved in a file named "untested", consists of a list of untested files, followed by a list of untested functions. More detailed execution statistics are given in the gcov log files which are saved in the top-level directory (named like src#hash.c.gcov). Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk>

  # Define NO_OPENSSL if you do not have OpenSSL, or if you simply want
  # to use the bundled (Mozilla) SHA1 routines. (The bundled SHA1
  # routines are reported to be faster than OpenSSL on some platforms)
