[cdt-dev] Support for "target-detach" and "target-disconnect"

[Mikhail Khodjaiants <mikhailkhod@xxxxxxxxxxxxxx>]

As the world domination of TCF hasn't been confirmed those of us who get 
paid for supporting GDB just have to keep going.

Currently both GDB-based implementations use the "Disconnect" action of 
the Debug view for sending the "detach" command to GDB. This is 
misleading because there is the "disconnect" command in GDB.
I proposing to add a new action for detach (only to the context menu, 
not toolbar) and change the implementation of the "Disconnect" action. 
The ideal place for this action is the John's 
"org.eclipse.cdt.debug.gdb.ui" plugin. The corresponding commands will 
be contributed by the corresponding CDI and DSF plugins.

Thoughts, suggestions, objections?

Thanks,
Mikhail
