[MI non-stop 07/11, RFA] Allow all CLI command even if target is executing.

[Vladimir Prus <vladimir at codesourcery dot com>]

There are several strategies to accepting commands when inferior_ptid is
running. One approach is to plain disallow all commands when inferior_ptid
is running.  This seems too strict.  Clearly, setting ignore count of 
a breakpoint does not require any access to the target at all.  Another 
approach is to document which commands may be allowed when the target is 
running. The problem is that each individual command may work or not work 
depending on the properties of the target. 

So, it's better to allow all commands up-front, and emit an error if we 
try an operation that the current target does not allow. This way, we'll 
never mistakenly prevent an operation that the target actually can perform.
In case of error, the frontend may show the error to the user, and user 
change either change his mind, or explicitly stop a thread, or ask the 
frontend to implicitly interrupt the target, or ask gdb to do same.

OK?
