Merge branch 'jk/leak-checkers'
Many of our programs consider that it is OK to release dynamic storage that is used throughout the life of the program by simply exiting, but this makes it harder to leak detection tools to avoid reporting false positives. Plug many existing leaks and introduce a mechanism for developers to mark that the region of memory pointed by a pointer is not lost/leaking to help these tools. * jk/leak-checkers: add UNLEAK annotation for reducing leak false positives set_git_dir: handle feeding gitdir to itself repository: free fields before overwriting them reset: free allocated tree buffers reset: make tree counting less confusing config: plug user_config leak update-index: fix cache entry leak in add_one_file() add: free leaked pathspec after add_files_to_cache() test-lib: set LSAN_OPTIONS to abort by default test-lib: --valgrind should not override --verbose-log
