A small patchset to update the verbs API documentation with some information regarding the ioctl syscall. First patch converts the file format to ReST, since this is the new preferred format. 2nd patch links this file to the main index so we can actually find it by browsing (search will work in any case). 3rd patch adds the new content, documenting a bit of the internal workings of the kernel side of the API functions. The goal is to make it easier for developers unfamiliar with the structure to understand what is going on when adding a new function.
