and run fsck with -f on clean shutdown instead.
With -f, fsck.f2fs always performs a full scan of the /data
partition regardless of whether the partition is clean or not.
The full scan takes more than 2 seconds on volantis-userdebug
and delays the OS boot.
With -a, the command does almost nothing when the partition
is clean and finishes within 20-30ms on volantis-userdebug.
When the partition has an error or its check point has
CP_FSCK_FLAG (aka "need_fsck"), the command does exactly the
same full scan as -f to fix it.

The log_target parameter of android_fork_execvp_ext() is now a
bit field, and multiple targets can be set to log to multiple
places at the same time.
The new target LOG_FILE will log to a file specified by the new
parameter file_path.
Set LOG_FILE and log to a file in /dev (the only writable filesystem
avilable when e2fsck runs) when invoking e2fsck in fs_mgr.

Also add ability to do abbreviated logging where only the first
4K bytes and last 4K bytes of output are added to the desginated log.
Also update standalog logwrapper command to support the new options.

Replace the old signal handling mechanism with a check of POLLHUP
to check when the child has died.

Add a lock around android_fork_execvp to ensure no two threads can
execute it at the same time.

When passing a NULL status to android_fork_execvp the return
status will now be the return value of the child if it exited
properly, otherwise a non-0 value will be returned.

sigprocmask has undefined behavior when called from a thread.
Replacing with pthread_sigmask to ensure correct behavior if
logwrap() gets called from a thread.

- Wait for the child to exit before propagating SIGINT and SIGQUIT
to the parent
- Add ignore_int_quit argument to logwrap() that gives the caller the
option to ignore SIGINT and SIGQUIT while logwrap is running

Always exit the child process with _exit() rather than exit() to ensure none
of the parent's atexit functions get called if the child needs to exit before
calling exec.

Android allows all users to write to log.
The setuid/setgid call is unneeded and could cause unintended
side effects when called from daemons or programs that need
to run as root.

Switch to a signal handler to monitor SIGCHLD.
Also, clean up the exit path and log a warning when the
previous SIGCHLD sigaction is not default or ignore.

Sometimes the read on the PTY can wait indefinitely if the child
dies. By using a poll statement that monitors both the output
of the child and its state we prevent this from happening.
