Custom allocator

[abnara]

Builder’s custom init function provides mechanism to provide custom allocator to flatcc builder.

The flatcc_builder_alloc_fun contains alloc and free calls. This allows multiple flatcc builders in a project to have different alloc and free functions. This just requires a new function to be sent during init.

Any reason why the same was functionality was not extended to flatcc_builder_emit_fun?
Theoretically, flatcc_builder_custom_init and emitter.c can be modified to make it behave similar to alloc_fun. But does this cause any known issues?

Similarly refmap and json_printer don’t expose this functionality.

Does someone know about this?
