As reported by @Crispy-fried-chicken in issue #1133 there is a potential
XXE vulnerability here. This fixes this problem by verifying the value
of `vmf->pgff` does not exceed the bounds of the memory mapping.
Fixes : #1133

[module] fault in pages one by one for ivshmem devices
...
It appears that the PCI BAR memory is slow to access with remap_pfn_range
and that it should instead be faulted in one page at a time.

* mmaping 0-offset dmabuf with 1 page offset
* mmaping page-offset dmabuf with 0 offset
* mmaping page-offset dmabuf with 1 page offset
* mmaping device with 0 offset
* mmaping device with 1 page offset

[module] implement mmap on PCI kvmfr devices
...
This allows PCI kvmfr devices to be directly mmap'd just like in-memory
ones. Also, the more efficient mmap implementation is used for mapping
the dmabuf, avoiding the faulting code entirely.

[module] improve dmabuf mmap logic for vmalloc'd memory
...
Instead of faulting the pages in one by one when mmaping on the dma fd,
we could instead use remap_vmalloc_range to map in all the memory at
once.

[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.

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
