drh 4a50aac564 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)

pointers into many internal interfaces.  Also added more mutexing. (CVS 4263)
