Move all the libcfs_ioctl_handler code from libcfs_ioctl.h to libcfs.h. The header libcfs_ioctl.h is a uapi header so their is no reason to keep kernel internals in that header.

Commit 4671a0266 change the parameter of the second parameter of cfs_precpt_alloc() from a sizeof type to sizeof type *pointer. This was incorrect in this case and it caused a crash when the LNet layer was brought up in my testing. The reason is cfs_precpt_alloc() creates an array of items where the arrays size is equal to the number of CPTs that exist. Changing to type *pointer only had cfs_precpt_alloc() create an array of pointers instead of an array of actual data structures. This patch reverse this change and adds comments to explain what cfs_precpt_alloc() is actually doing to avoid potential issues like this again. Changelog: v1) Simple revert of the original patch v2) Added in comments to explain why cfs_precpt_alloc() has the arguments it uses.
