The sparse-based checking for non-RCU accesses to RCU-protected pointers
has been around for a very long time, and it is now the only type of
sparse-based checking that is optional. This commit therefore makes
it unconditional.

Add documentation of -DCONFIG_SPARSE_RCU_POINTER.
I started to add documentation of -D__CHECK_ENDIAN__ as well, but
discovered I'm too late; that's now enabled by default.

We dropped __CHECK_ENDIAN__ so __bitwise__ is now an implementation
detail. People should use __bitwise everywhere.

Fold the sparse document into the development tools set; no changes to the
text itself beyond formatting.
