Fix boost intrusive_ptr testcase compilation with latest boost/gcc
Fixes for warnings issued by clang
Warning fix for ccache-swig tests

clang deletes the output 'file' whereas gcc does not if the output
'file' is actually a directory.
Make guile test suite default to scm api

In other words guilescm becomes guile.
Deprecated gh api tests are moved to guilegh.
Add support for guile 2.0: update swg and interface files

Note: only the scm interface is considered.
Add support for guile 2.0: configure and makefiles.

Note: guile-config is badly broken for guile 2. So
the guile configure  section has been rewritten to
use pkg-config instead.

Manually resolved conflicts:
	Examples/Makefile.in
Drop support for guile 1.6 and older
Drop guilegh interface

All of guile's interface files now use the scm interface.
This should not affect any users. Swig generated code
using the scm interface can be mixed with gh interface
using user code.
It does simplify maintenance of the guile swig code though.
Fix deprecation warnings for test suite under guile 2.0
guile: fix std_map.i "$1 not found" error
Some C++ experience needed

This is the main problem - it is saying there is no default assignment
operator (because one of the members in pair is const). The solution is
to avoid assignment. I've attached a patch to do this plus some error
message corrections.

Use freearg instead of argout to free temp variable
Disable guile 2's autocompilation feature for the test suite

Autocompilation generates a lot of warnings. Most of them
just informational, but it clutters the test output.
Add guile test for guile 2
guile: fix integer test on 64 bit systems
guile: fix matrix example

- add missing library in link phase
- empty true path () for if is not allowed
guile: fix multimap example

- fix compiler warning
- fix guile 2 deprecation warnings
- minor cleanup of generated code
guile: emit warning when -gh or -scm option are used
Don't use obsolete -scm option in own makefiles
Remove deprecated Guile options from help.

Also use wording for deprecated options warning which is consistent with
elsewhere.
