[module] support in-memory kvmfr devices
...
Added an array option static_size_mb to the kvmfr module to create a
list of in-memory kvmfr devices. These devices support dmabuf just like
normal kvmfr devices. Additionally, they can be mmap'd, which allows
them to be passed to qemu as ivshmem devices.

[all] use explicit void parameter lists
...
This makes it a compile-time error to call a function that semantically
takes no parameters with a nonzero number of arguments.
Previously, such code would still compile, but risk blowing up the stack
if a compiler chose to use something other than caller-cleanup calling
conventions.

Rewrite dkms.conf
...
1) With the change to the Makefile, this update allows dkms to build and install the module for different kernels.
2) As per dkms documentation, no use of ${dkms_tree}.
3) Removed the use of REMAKE_INITRD as this module is not needed that early in the boot process.
4) Updated version to match what's defined in the module
