Since SSE4 is now part of the minimum requirements for DPDK, we don't need
a fallback case to handle selection of algorithm when SSE4 is unavailable.

Our x86 baseline is to have support for SSE4.2, so therefore there is no
point in conditions around the inclusion of SSE1 - SSE4 headers.

Increase the default baseline from "core2" architecture to "corei7". This
means that all builds will have SSE4.2 support included, and we can remove
special case manipulation of CFLAGS for the same. Naturally, this does mean
that some machines that previously could run DPDK now can't do so, but
hardware with SSE4.2 has been around for almost a decade now, so this
should not be a major problem.

Don't zero the pages during each mmap. Instead, only zero the pages
when they are not already mmapped. Otherwise, the multi-process
support will be broken, as the pages will be zeroed when secondary
processes map the memory. Besides, track the open and mmap operations
on the cdev, and prevent the module from being unloaded when it is
still in use.
