MFC r332387: Annotate geom modules with MODULE_VERSION
GEOM ELI may double ask the password during boot. Once at loader time, and once at init time.
This happens due a module loading bug. By default GEOM ELI caches the password in the kernel, but without the MODULE_VERSION annotation, the kernel loads over the kernel module, even if the GEOM ELI was compiled into the kernel. In this case, the newly loaded module purges/invalidates/overwrites the GEOM ELI's password cache, which causes the double asking.
This MFC commit differs slightly from head, due to pc98 removal. These changes were trivial and should be obvious.

Despite several examples in the kernel, the third argument of sysctl_handle_int is not sizeof the int type you want to export. The type must always be an int or an unsigned int.
Remove the instances where a sizeof(variable) is passed to stop people accidently cut and pasting these examples.
In a few places this was sysctl_handle_int was being used on 64 bit types, which would truncate the value to be exported. In these cases use sysctl_handle_quad to export them and change the format to Q so that sysctl(1) can still print them.

A GEOM cache can speed up read performance by sending fixed size read requests to its consumer. It has been developed to address the problem of a horrible read performance of a 64k blocksize FS residing on a RAID3 array with 8 data components, where a single disk component would only get 8k read requests, thus effectively killing disk performance under high load. Documentation will be provided later. I'd like to thank Vsevolod Lobko for his bright ideas, and Pawel Jakub Dawidek for helping me fix the nasty bug.
