spdk_bit_pool is a wrapper around spdk_bit_array with the intentions of providing much better performance for allocating from a fragmented bit array. The cost of searching a large bit array for a cleared bit can become expensive so the spdk_bit_pool will provide an ability to track extents of recently cleared bits. This initial commit does not adding the tracking yet - it is strictly a wrapper around spdk_bit_array with enough functionality to replace the use of spdk_bit_pool in SPDK blobstore with equivalent performance. This will allow us to switch blobstore to use this minimal wrapper first, and then iteratively improve spdk_bit_pool to provide the better performance.
