The C front-end created symbols that had the function set to an empty string. This was not accurately represented in the JSON representation, but also shouldn't be used at all. Thus, changing the parser rather than the JSON serialisation.
We were previously only printing a subset, making it impossible to restore a `source_locationt` from its JSON representation.
The JSON output of a `source_locationt` is different from generic
`irept`.
Also, make `try_get_{bool,string}` publicly available for subsequent
re-use.
We must include all information required to re-produce a goto program from its JSON representation.
Adds a parser for JSON-encoded `goto_functionst` and support to `symtab2gb` to optionally read such from a file and store them in `goto_functions` of a `goto_modelt`.
Tests the full workflow of reading and writing JSON.
