xen/tmem: Remove the boot options and fold them in the tmem.X parameters.
If tmem is built-in or a module, the user has the option on the command line to influence it by doing: tmem.<some option> instead of having a variety of "nocleancache", and "nofrontswap". The others: "noselfballooning" and "selfballooning"; and "noselfshrink" are in a different driver xen-selfballoon.c and the patches: xen/tmem: Remove the usage of 'noselfshrink' and use 'tmem.selfshrink' bool instead. xen/tmem: Remove the usage of 'noselfballoon','selfballoon' and use 'tmem.selfballon' bool instead. remove them. Also add documentation. Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
