This series synchronizes mmap.c with the bsd-user fork. This is a mix of old bug
fixes pulled in from linux-user, as well as some newer fixes to adress bugs
found in check-tcg and recent FreeBSD developments. There are also a couple of
style commits.

Guy Yur (1):
  bsd-user: Don't try to mmap fd when it is -1 independently from
    MAP_ANONYMOUS flag

Kyle Evans (1):
  bsd-user: Implement MAP_EXCL, required by jemalloc in head

Mikaël Urankar (2):
  bsd-user: Apply e6deac9cf99 from linux-user (zero anonymous memory)
  bsd-user: Apply fb7e378cf9c from linux-user (fix FORTIFY warnings)

Paolo Bonzini (1):
  bsd-user: Apply 86abac06c14 from linux-user (target_mprotect can't
    fail)

Warner Losh (4):
  bsd-user: MAP_ symbols are defined, so no need for ifdefs
  bsd-user: mmap return ENOMEM on overflow
  bsd-user: mmap prefer MAP_ANON for BSD
  bsd-user: mmap line wrap change
