Avoid looping in transaction output.
Update app-layer API to store the bits in one step
and retrieve the bits in a single step as well.
Update users of the API.
Converting the NTP parser to the new registration method is a simple,
3-steps process:
- change the extern functions to use generic input parameters (functions
in all parsers must share common types to be generic) and cast them
- declare the Parser structure
- remove the C code and call the registration function
Add Rust support for the common interface to declare and register all
parsers.
Add a common structure definition to contain all required elements
required for registering a parser, similar to the C interface.
This also reduces the risk of incorrectly registering a parser: the
compiler prevents omitting required functions from the structure, and
functions (even if external) are type-checked. Optional functions are
explicitly marked.
