OCF requires memory retrived from mempool to be filled with zeros.
When mempool is created, information about element size is stored to be used
when new memory is retrived.
This is fix for issue #671

Use mempool for allocating OCF requests with constant size
Previous method was using mallocs which is significantly slower

Add OCF module based on OCF meta-library
Open CAS Framwework (OCF) is high performance block storage
caching meta-library
It is open-source, published at https://github.com/Open-CAS/ocf
With this patch OCF-enabled device is represented in SPDK
as virtual bdev having core and caching devices as its base devices
This patch includes implementation of:
* OCF top adapter (vbdev_ocf.c)
* OCF bottom adapter (dobj.c, data.c)
* Adaptation layer for OCF (env/)
* OCF context abstractions (ctx.c)
Adaptation layer and context abstractions are not dependent on SPDK bdev
OCF bdev supports reads and writes, configured at startup
Other features will be added with separate patches
