Move platform specific Linux source under module/os/linux/
and update the build system accordingly. Additional code
restructuring will follow to make the common code fully
portable.

Move platform specific Linux headers under include/os/linux/.
Update the build system accordingly to detect the platform.
This lays some of the initial groundwork to supporting building
for other platforms.
As part of this change it was necessary to create both a user
and kernel space sys/simd.h header which can be included in
either context. No functional change, the source has been
refactored and the relevant #include's updated.

The existing mechanisms for determining what code is running in the
kernel do not always correctly report the git hash. The versions
reported there do not reflect changes made since `configure` was run
(i.e. incremental builds do not update the version) and they are
misleading if git tags are not set up properly. This applies to
`modinfo zfs`, `dmesg`, and `/sys/module/zfs/version`.
There are complicated requirements on how the existing version is
generated. Therefore we are leaving that alone, and adding a new
mechanism to record and retrieve the git hash:
`cat /proc/sys/kernel/spl/gitrev`
The gitrev is re-generated at compile time, when running `make`
(including for incremental builds). The value is the output of `git
describe` (or "unknown" if not in a git repo or there are uncommitted
changes).
We're also removing /proc/sys/kernel/spl/version, which was never very
useful.
