The connector test code currently does not work out of the box.  This is
because it uses a connector id that is above the registered limit.  So
rather than force people to stumble through undocumented code wondering
why it isn't working, have the test code use one of the "private" ids by
default.  While I'm in here, clean up the code (kernel and user app) so
that it's a bit more user friendly and verbose in significant things that
it does.  Terse test code wastes people time as they simply enumerate it
with all the same kind of debug messages to get a better feel of what code
is running at any time.

Currently source files in the Documentation/ sub-dir can easily bit-rot
since they are not generally buildable, either because they are hidden in
text files or because there are no Makefile rules for them.  This needs to
be fixed so that the source files remain usable and good examples of code
instead of bad examples.

Add the ability to build source files that are in the Documentation/ dir.
Add to Kconfig as "BUILD_DOCSRC" config symbol.

Use "CONFIG_BUILD_DOCSRC=1 make ..." to build objects from the
Documentation/ sources.  Or enable BUILD_DOCSRC in the *config system.
However, this symbol depends on HEADERS_CHECK since the header files need
to be installed (for userspace builds).

Built (using cross-tools) for x86-64, i386, alpha, ia64, sparc32,
sparc64, powerpc, sh, m68k, & mips.
