Improvements to memory leak detection. The --backtrace=NNN option is now

recognized by tester.tcl.  Memory leak summaries are automatically written
to the file ./memleak.txt and each leak is tagged with the test in which
it occurred.  The quick.test script runs on Linux with no errors and
no leaks. (CVS 4273)
