Also add some parameters check to this API.

The CL object with ref == 0 should be considered
as a invalid object.

We use context's lock when we add and delete cl objects.
Every cl object should use it's own lock to protect itself.
We also add some helper functions to ease the adding and
removing operations.

To make the license statement consistent to each other, adjust
all license versions to v2.1+. Thus beignet should have a pure
LGPL v2.1+ license.

This is the first step to do image/sampler allocation fully
at compile time. Thus we can determine all the sampler id and image
bti index at compile time. So it can make the following things
easier or faster:
1. After we finish both image/sampler, we can treat all image bti and sampler
as constant and can get their value when we encode the Sampler and TypedWrite
instructions. Then we don't need to compute the message header at runtime which
cost 3 instructions each call.
2. get image width/height/depth. As we know the surface bti at compile time,
we can put those data at specified curbe entry and generate correct indirect
register access to get those information at compile time.
This is the first step. And just finish the sampler part. Now all the
samplers including those defeined in kernel arguments will be allocated
at compile time. At runtime, it just need to fill in the sampler value
into the proper slot which map to the specified input argument. Then the
driver will create and bind the sampler to the correct slot.

We changed the way to handle samplers. We gather all the kernel side
defined samplers and those sampler in kernel argument into one samplers
array. And don't allocate one single sampler each time.

This adds a pointer to the dispatch table at the beginning of every object
of type
- cl_command_queue
- cl_context
- cl_device_id
- cl_event
- cl_kernel
- cl_mem
- cl_platform_id
- cl_program
- cl_sampler
as required by the ICD specification. The layout of the dispatch table
comes from the OpenCL ICD loader by Brice Videau <brice.videau@imag.fr> and
Vincent Danjean <Vincent.Danjean@ens-lyon.org>.
To avoid dispatch table entries being overwritten with the ICD loader's
implementations of the CL functions (as would be the proper behaviour for
the ELF loader), the -Bsymbolic option is given to the linker.
