Refactor the code by making splat_test_{init,fini}, splat_subsystem_{init,fini}
into functions. They don't have reason to be macro and it would be too bloated
to inline every call.

Attempting to perform a vfs_rename() on Linux 4.2 and newer kernels
results in an EACCES error. Rather than attempting to add and
maintain more ugly compatibility code it's best to just retire
this interface. As a first step the SPLAT test is disabled for
Linux 4.2 and newer kernels.

As of Linux 3.4 the UMH_WAIT_* constants were renumbered. In
particular, the meaning of "1" changed from UMH_WAIT_PROC (wait for
process to complete), to UMH_WAIT_EXEC (wait for the exec, but not the
process). A number of call sites used the number 1 instead of the
constant name, so the behavior was not as expected on kernels with
this change.

Restructure the the SPLAT headers such that each test only
includes the minimal set of headers it requires.

Commit torvalds/linux@b8318b0 moved the __clear_close_on_exec()
function out of include/linux/fdtable.h and in to fs/file.c
making it unavailable to the SPL.
Now as it turns out we only used this function to tear down
some test infrastructure for the vn_getf()/vn_releasef() SPLAT
regression tests. Rather than implement even more autoconf
compatibilty code to handle this we just remove the test case.
This also allows us to drop three existing autoconf tests.
This does mean the SPLAT tests will no longer verify these
functions but historically they have never been a problem.
And if we feel we absolutely need this test coverage I'm
sure a more portable version of the test case could be added.

Closes#183
torvalds/linux@1dce27c5aa introduced
__clear_close_on_exec() as a replacement for FD_CLR. Further commits
appear to have removed FD_CLR from the Linux source tree. This
causes the following failure:
error: implicit declaration of function '__FD_CLR'
[-Werror=implicit-function-declaration]
To correct this we update the code to use the current
__clear_close_on_exec() interface for readability. Then we introduce
an autotools check to determine if __clear_close_on_exec() is available.
If it isn't then we define some compatibility logic which used the older
FD_CLR() interface.

Previously these were defined to noops but rather than give
the misleading impression that these are actually implemented
I'm removing the type entirely for clarity.
Updated AUTHORS, COPYING, DISCLAIMER, and INSTALL files. Added
standardized headers to all source file to clearly indicate the
copyright, license, and to give credit where credit is due.
I must have been in a hurry when I wrote the vnode regression tests
because the error code handling is not correct. The Solaris vnode
API returns positive errno's, these need to be converted to negative
errno's for Linux before being passed back to user space. Otherwise
the test hardness with report the failure but errno will not be set
with the correct error code.
Additionally tests 3, 4, 6, and 7 may fail in the test file already
exists. To avoid false positives a user mode helper has added to
remove the test files in /tmp/ before running the actual test.
- Proper ioctl() 32/64-bit binary compatibility. We need to ensure the
ioctl data itself is always packed the same for 32/64-bit binaries.
Additionally, the correct thing to do is encode this size in bytes
as part of the command using _IOC_SIZE().
- Minor formatting changes to respect the 80 character limit.
- Move all SPLAT_SUBSYSTEM_* defines in to splat-ctl.h.
- Increase SPLAT_SUBSYSTEM_UNKNOWN because we were getting close
to accidentally using it for a real registered subsystem.
