This effectively reverts commit 17eba16b. It looks like these flags have
been introduced as part of the onefs support which has been removed
again. As there is no other use for the flags, remove them.

Since commit 9c51b278b1700cd5f3e2addc19b7c711cc2ea10b the compiler has
been able to inline the affected call to uint16_checksum().  Given
that the data (phdr) is being accessed by an incompatible
pointer (data) there is an aliasing problem when the call is inlined.
This results in incorrect behaviour with -O2/-O3 when compiling with
at least GCC 6, 7, and 8.

Fix this by making the types compatible.

Also fixes CID 1437604 (Reliance on integer endianness).  This is a
false positive because the uint16_checksum doesn't depend on the order
of the input uint16_t items.

vfs_fruit: Don't unlink the main file

The original fix for bug 13441 was missing a check that verifies that
fruit_ftruncate() is actually called on a stream.

do_lock() returns a valid br_lck even in case of a locking conflict.
Not free'ing it leads to a invalid lock order panic later, because
"br_lck" corresponds to a dbwrap lock on brlock.tdb.

s3: util: Do not take over stderr when there is no log file

In case we don't have either a /var/log/samba directory, or pass a
non-existent log directory through '-l' option, all commands that are
daemonized with '-D' option hang when executed within a subshell.

An example on how to trigger that:

  # rm -r /var/log/samba
  # s=$(nmbd -D -s /etc/samba/smb.conf -l /foo123)
  (never returns)

So, when the above command is executed within a subshell the following
happens:

  (a) Parent shell creates a pipe, sets write side of it to fd 1
    (stdout), call read() on read-side fd, forks off a new child process
    and then executes nmbd in it.
  (b) nmbd sets up initial logging to go through fd 1 (stdout) by
    calling setup_logging(..., DEBUG_DEFAULT_STDOUT). 'state.fd' is now
    set to 1.
  (c) reopen_logs() is called by the first time which then calls
    reopen_logs_internal()
  (d) in reopen_logs_internal(), it attempts to create log.nmbd file in
    /foo123 directory and fails because directory doesn't exist.
  (e) Regardless whether the log file was created or not, it calls
    dup2(state.fd, 2) which dups fd 1 into fd 2.
  (f) At some point, fd 0 and 1 are closed and set to /dev/null

The problem with that is because parent shell in (a) is still blocked in
read() call and the new write side of the pipe is now fd 2 -- after
dup2() in (e) -- and remains unclosed.
