Completion of error handling

[elfring]

Would you like to add more error handling for return values from functions like the following?

• malloc ⇒ jsonnet_evaluate_snippet_aux
• jsonnet_realloc ⇒ from_string

Yes that's needed.

I suggest to avoid ignorance of return values a bit more.

Are you interested to apply aspect-oriented software development?
How do you think about to encapsulate error detection and corresponding exception handling as a reusable aspect in your software?

Thanks for your small source code improvement.
