MI: changing breakpoint location

[Vladimir Prus]

Hello!

At the moment, the MI interface does not allow one to change location of
breakpoint, say to move breakpoint from main.cpp:9 to main.cpp:11.
CLI does not support this either, but I'm interested in MI.

Was this an explicit design decision, or it just happened this way? The use
case when it matters if when, in KDevelop, user edits the field of
breakpoint table with the location.

Now, I have to delete the old breakpoint and create the new one, which is
workable, but not convenient. How about adding 'change breakpoint location'
functionality to MI?
