Enable building bindings with SWIG >= 3.0.6

This reinstates r1690591 and adds the minimum version checks for SWIG
proposed by Joe Orton in http://svn.haxx.se/dev/archive-2015-07/0028.shtml.

* build/ac-macros/swig.m4,
  subversion/bindings/swig/INSTALL:
  Change version check and documentation to allow SWIG >= 3.0.6

* subversion/bindings/swig/include/proxy.swg:
  Use %{ %} with %pythoncode so comments avoid the SWIG processor,
  fixing the bindings with SWIG >= 3.0.6.

Fix Python bindings with SWIG < 3.0.6, followup on 1721488.

“%pythoncode { ... }” had to be changed to “%pythoncode %{ ... %}” to avoid
macro expansion (done in r1721488).  This was a latent bug in the bindings
exposed by stricter parsing in SWIG 3.x.

However, there was a bug in SWIG through 3.0.6 which would remove part of the
commented lines inside the “%pythoncode %{ ... %}” block.  This caused the
"right" fix to break everywhere except 3.0.6+.

As discussed in the SWIG bug tracker[0], an alternative form of the pythoncode
directive can be used to inline the contents of a specified file.  Use of this
form works in all supported SWIG versions.

[0]: https://github.com/swig/swig/issues/379#issuecomment-107664345

* subversion/bindings/swig/include/proxy.swg:
  (proxy_pythoncode): Copy %pythoncode contents to ...

* subversion/bindings/swig/include/proxy.py:
  ... new file which is included in proxy.swg via “%pythoncode "..."”
  directive.

* build/ac-macros/swig.m4
  subversion/bindings/swig/INSTALL:
  Remove 3.x related SWIG restrictions.  All SWIG versions are supported again.
