RFC: Implementation of QMP documentation retrieval command

[Niteesh G. S.]

Hello,

We now have a reasonably working prototype that is capable of sending/receiving

commands/responses, syntax highlighting, and a simple notification system. The

prototype can be found here https://gitlab.com/niteesh.gs/qemu/-/tree/aqmp-tui-prototype

Working on this prototype gives us a lot of hints on things to worry about and other

ideas that were worth implementing. Our next goal is to start working on the real TUI

based on this prototype.

One requested feature of the TUI was to show documentation for the commands typed.

To achieve this, a QMP command that lets us query the documentation from QEMU has

to be implemented and some discussion has already been done on it in a previous thread.

I request all continue that discussion here and suggest ideas regarding implementation.

The goal is to come up with something small and simple which can also be improved upon

after the summer.

I have a simple implementation of the command that returns dummy documentation here

Thanks,

Niteesh.
