Module Name:    src
Committed By:   joerg

Modified Files:
        src/external/bsd/jemalloc/dist/src: jemalloc.c
        src/lib/libc/gen: pthread_atfork.c
        src/lib/libc/include: extern.h
        src/lib/libc/stdlib: jemalloc.c malloc.c

Log Message:
Hook up proper fork lock handling for malloc:
- lock all relevant mutexes just before fork
- unlock all mutexes just after fork in the parent
- full reinit non-spinlocks in the child
This is not using the normal pthread_atfork interface to ensure order of
operation, malloc is used as implementation detail too often.
