Right now we seem to have 3 locks.
- devinfo.lock
This is a per device lock
- metaData.devicesLock
This is supposedely protecting map of devices.
- Global DeviceSet lock
This is protecting map of devices as well as serializing calls to libdevmapper.
Semantics of per devices lock and global deviceset lock seem to be very clear.
Even ordering between these two locks has been defined properly.
What is not clear is the need and ordering of metaData.devicesLock. Looks like
this lock is not necessary and global DeviceSet lock should be used to
protect map of devices as it is part of DeviceSet.
This patchset gets rid of metaData.devicesLock and instead uses DeviceSet
lock to protect map of devices.
Also at couple of places during initialization takes devices.Lock(). That
is not strictly necessary as there is supposed to be one thread of execution
during initializaiton. Still it makes the code clearer.
I think this makes code more clear and easier to understand and easier to
make further changes.

maxDeviceID is upper limit on device Id thin pool can support. Right now
we have this check only during startup. It is a good idea to move this
check in loadMetadata so that any time a device file is loaded and if it
is corrupted and device Id is more than maxDevieceID, it will be detected
right then and there.

Use deactivateDevice() instead of removeDevice() directly. This will make
sure for device deletion, deferred removal is used if user has configured
it in. Also this makes reading code litle easier as there is single function
to remove a device and that is deactivateDevice().

If a device is still mounted at the time of DeleteDevice(), that means
higher layers have not called Put() properly on the device and are trying
to delete it. This is a bug in the code where Get() and Put() have not been
properly paired up. Fail device deletion if it is still mounted.

device has map (device.Devices), contains valid devices and we skip all
the files which are not device files. transaction metadata file is not
device file. Skip this file when devices files are being read and loaded
into map.

Although having a request ID available throughout the codebase is very
valuable, the impact of requiring a Context as an argument to every
function in the codepath of an API request, is too significant and was
not properly understood at the time of the review.
Furthermore, mixing API-layer code with non-API-layer code makes the
latter usable only by API-layer code (one that has a notion of Context).

Fixes an issue where `VOLUME some_name:/foo` would be parsed as a named
volume, allowing access from the builder to any volume on the host.
This makes sure that named volumes must always be passed in as a bind.
