t: support clang/gcc AddressSanitizer
When git is compiled with "-fsanitize=address" (using clang or gcc >= 4.8), all invocations of git will check for buffer overflows. This is similar to running with valgrind, except that it is more thorough (because of the compiler support, function-local buffers can be checked, too) and runs much faster (making it much less painful to run the whole test suite with the checks turned on). Unlike valgrind, the magic happens at compile-time, so we don't need the same infrastructure in the test suite that we did to support --valgrind. But there are two things we can help with: 1. On some platforms, the leak-detector is on by default, and causes every invocation of "git init" (and thus every test script) to fail. Since running git with the leak detector is pointless, let's shut it off automatically in the tests, unless the user has already configured it. 2. When apache runs a CGI, it clears the environment of unknown variables. This means that the $ASAN_OPTIONS config doesn't make it to git-http-backend, and it dies due to the leak detector. Let's mark the variable as OK for apache to pass. With these two changes, running make CC=clang CFLAGS=-fsanitize=address test works out of the box.
