[RFA/RFC] Add dump and load command to process record and replay

[Simon Sobisch]

This RFC was about a way to store a command file along with recording 
and later be able to load it and reverse-step / step through it.
That idea sounds very cool and like something that I would use quite 
often, especially on longer debugging runs where the starting point 
takes a while to reach...

I've stumbled over this suggested patch which was discussed and adjusted 
multiple times in 2009 and then seem to be loose on a documentation 
question.

The last entry I've found to this was
https://sourceware.org/legacy-ml/gdb-patches/2009-09/msg00145.html

Can anyone share about the state of this patch?
Would anyone like to adjust this to the current source?

Thanks for any insights,
Simon
