Clean up various left over commented lines from dlopen to single
libhamlib transition. Remove unneeded configure variables.
Correct minor inconsistencies in Makefile.am files.
Define a new variable, READLINE_LIBS, so that only programs that offer
Readline support are linked against it.
Fix various compilation warnings and errors in test files revealed with
'make check' on MinGW.
Define rig and rotor backends to (mostly) be built in alphabetical
order.
Add the rig and rotor backends to the list of dependencies for
libhamlib.la so that updating a given backend will force libhamlib.la to
be relinked as well. Thanks to Bill Sommerville, G4WJS, for reporting
this.
Removed obsolete references and variables related to LTDL.
Moved all backend *.h files into the SOURCES primary as Automake
documentation states all source file types should be listed. This
causes Automake to include *.h files in rebuild rules for the targets.
Removed the '-DIN_HAMLIB' assignment from the CFLAGS primary in each
backend and assigned it to AM_CPPFLAGS in configure.ac. The effect is
the same and it simplifies the backend Makefile.am files.
Removed all commented lines.
Android makefile fragments are distributed as extra distribution files
by the GNU build system but are otherwise ignored. The Android build
support is independent and does not rely on the GNU build system.

Use the libtool link mode argument '-version-info' to set the Hamlib 3
ABI to be compatible with Hamlib 1.2 ABI. As the current ABI has not
been changed or removed, we should be able to maintain backward
compatibility. The libtool docs state that so long as the ABI is only
added to, backward compatibility should be maintained.
My idea here is to be able to have presently compiled programs be able
to use binary libraries of Hamlib 3 without recompiling. So far I have
tested this locally on Linux and Windows. More testing is welcome.
Initializing libltdl is now done by the LTDL_INIT macro in configure.ac.
This now creates a libltdl directory in the tree (not tracked in Git)
when autoreconf is run. The downside is that this complicates the build
a little bit with the advantage that the build can now take place on a
system that does not have libltdl-dev installed as Hamlib will build on
such systems by passing the '--with-included-ltdl' flag to the configure
script. In particular, this simplifies the build on Linux for the mingw32
host by not having to run libtoolize manually and assures that libltdl
is built with the same build and host architectures as Hamlib.
Now check if '--with-included-ltdl' has been passed to configure and if
not, only then test for the presence of an installed ltdl.h.
Commented out AM_MAINTAINER_MODE macro. It is recommended by the
Automake manual that this macro and its configure options not be used as
the Autotools system is designed to regenerate its files. Let me know
if this is problem as it can be reversed easily enough. The autogen.sh
script no longer passes the '--enable-maintainer-mode' option to
configure when bootstrapping the build system from Git.
Minor edits in configure.ac to improve readability.
Updated build-win32 files in scripts/
