Instead of the large set of indirecting macros, define the few needed
macros to directly instantiate the struct uverbs_oject_tree_def and
associated objects list.
This is small amount of code duplication but the readability is far
better.

Introduce a new macro to be used for global methods on a singleton
object.
This macros sets internally the type_attrs to be NULL as such an object
can't be created.
Downstream patches from this series will use this macro.

Previously, adding driver specific attributes required drivers to
declare all the hierarchy - object tree, object, methods and the
attributes themselves. A common use case is adding a few attributes to
an existing common method.
In order to simplify the driver's code, we add some macros to do all
these declarations automatically.

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.
