Better support for C enum.

[stephan57160]

See discussion in #419.

Create a 'enum' in .h file, with same values than in C++. Difference are the names of the 'constants' : In C, the enum name is prepended before the RUST enum name.

Testing tool are also available in tests/expectations.

Note:

• generate_c_code_for_enum is renamed as generate_cpp_code_for_enum, as it is actually generating code for C++.
• generated_c_code_for_enum is created to generate C code !

I see also a conflicting files, which was nos there previsously. I'll change that too, no problem.

You prefer different commits, or a squash of all ?

I suppose "squash" is better for such small feature, too make life easier during "git bisect".

I removed empty line in enum generator, and I suppose this is cause conflicts.

New tests added, after seeing the new enum syntax.

No. Mistake was on my side. I simply did not fetch upstream/master and did not get the new 'enum syntax' PR. Before I understood this, I had a few push attempts ... It's fixed now, and I added some more tests, with this too.
