IB/uverbs: Move to new headers and make naming consistent
Use macros to make names consistent in ioctl() uAPI: The ioctl() uAPI works with object-method hierarchy. The method part also states which handler should be executed when this method is called from user-space. Therefore, we need to tie method, method's id, method's handler and the object owning this method together. Previously, this was done through explicit developer chosen names. This makes grepping the code harder. Changing the method's name, method's handler and object's name to be automatically generated based on the ids. The headers are split in a way so they be included and used by user-space. One header strictly contains structures that are used directly by user-space applications, where another header is used for internal library (i.e. libibverbs) to form the ioctl() commands. Other header simply contains the required general command structure.
