Now we skip mountpoints that are repeated.

open(O_DIRECTORY) returns an error if the open attempt
is against anything other than a directory. This basically
duplicates the check that the stat() call was trying to do.
Eliminate the unnecessary stat() call and use O_DIRECTORY
instead.

If fstrim thread creation or detachment is failed, wakelock can be leaked.
So move wakelock acquire to do_fstrim_filesystems function

As it is not upstream, it doesn't belong in the external/kernel-headers
... or in bionic's cleaned up copy.
It matches what is in common/android-3.10.

This adds an "fstrim dodtrim" command which will attempt to use
the FIDTRIM ioctl() if FIDTRIM is defined in the uapi/linux/fs.h.
If not, it will fail with EINVAL.
If no FIDTRIM is defined, it does not affect the "fstrim dotrim".

Replace MINOR(dev_t) and MAJOR(dev_t) with minor and major,
which cast to int.
Cast int to uintptr_t before casting to pointer

Fstrim can take a while, so grab a wakelock so it finishes now,
not when the user picks up the device and wakes it back up.
This change does not protect against multiple calls to fstrim
before the first one completes. When the first one completes, it
will release the wakelock, and the device will go to sleep.
However, normal usage is this will not be invoked by the framework
more than once a day, so this should not be an issue.

Some devices can take up to a few minutes to do fstrim. If done
in the same thread as the rest of the vold command listener, then
vold is blocked from responding to any other commands until the
trim is done. So create a thread to do the work, and return
immediately.

The fstrim subsystem implements the dotrim command, which goes
through all the writable filesystems on the device, and invokes
the FITRIM ioctl() on them. This marks all the unused blocks on
the underlying flash device as unused, so the device performs better.
