c: Support for more code styles

[IngoMeyer441]

I modified the c function parser to support coding styles that put the return value on the same line as the function name:

int main() {...

It is compatible with the old behavior of the plugin.

Thank you for the patch! But it doesn't work for code like the following:

/**
 * ... some description ...
 */
int foo(void)
{
  return 42;
}

vaf should select the last 4 lines, but the modified version selects also the third line (*/).

Thanks for your fast reply. :) Maybe the following is more robust:

1. Remove all comments from the first line (that was intended to contain the return type before)
2. Strip leading and trailing white space
3. Check if the reduced line ends with } or ;. If not assume that it contains a return type and select it. Otherwise, it is a comment, ending function or a statement and it does not belong to the selected function.
