* add a flag to use MAP_PRIVATE in memfs_malloc (gangren)

        * pthread_self() is now safe to use early (ppluzhnikov)
        * windows support for pprof: nul and /usr/bin/file (csilvers)
        * fix tc_malloc_size for debugallocation (csilvers)
        * add test on strdup to tcmalloc_test (csilvers)
        * augment heap-checker to deal with no-inode maps (csilvers)
	* Get rid of -Wno-unused-result: not all gcc's support it (csilvers)
	* /bin/true -> ':', which is faster and more portable (csilvers)
