Joydeep Biswas c964fce90c Fix bug in cuda_kernels_test 
* Use the context stream, not the default stream, since all
  CUDA operations now operate on the context stream.

Joydeep Biswas fc826c5780 CUDA Cleanup 
* All Cuda* objects now take in a ContextImpl* during
  construction, and save the context instead of individual
  handles.
* Since we no longer use the legacy default stream, we need to
  explicitly synchronize the stream before performing GPU->CPU
  transfers, and CudaBuffer is responsible for such synchronization
  when asked to perform GPU to CPU transfers.
* Remove all manual syncs and relegate syncing to CudaBuffer
  before performing GPU to CPU transfers.

Sameer Agarwal 6085e45be7 Minor CUDA cleanup. 
1. ceres_cuda_kernels.cu -> cuda_kernels.cu.cc
2. Add missing ifdef guards.
3. Fix an errant namespace

Sameer Agarwal 04899645cc LinearOperator::FooMultiply -> LinearOperator::FooMultiplyAndAccumulate 
These methods were historically poorly named and every time I read code
I get confused whether they are just multiplying or multiplying and
adding. Clarifying them also gives us the changce to introduce
RightMultiply and LeftMultiply methods in the base class which will
simplify a number call sites in a subsequent CL.

Joydeep Biswas d8dad14eed CUDA Cleanup 
* Renamed several interfaces to CudaBuffer for clarity and consistency.
* Added unit tests for custom Cuda kernels.
* Set specific CUDA architectures if the CMake version supports it.
