Rewrite make-dissector-reg.py in C

The output compares equal to make-dissector-reg.py and the regex
should be more robust (multiline, complete start of function definition).

The primary motivation is to clean up the python script. This small
binary results in much cleaner code. The python script is used only
to generate plugin code, therefore it is renamed.

Also in my casual measurements the C code is much faster (without cache)
than the python script with the cache.
