As part of Bug 348159 the DSF-GDB preference store was moved from
the dsf.gdb.ui plugin to the dsf.gdb plugin. This is because
we needed to have the preference store initialize without
requiring the user of the UI plugin.
In GdbUIPlugin.getPreferenceStore(), we return the store of the
dsf.gdb plugin, which is why things still work if you add
".ui".

GDBControl is used for GDB < 7.0
GDBControl_7_0 for GDB 7.0 and 7.1
GDBControl_7_2 (which extends GDBControl_7_0) for GDB >= 7.2
When adding a new feature, you have to decide to which GDB
version the feature apply, and add it to the proper class,
or create a new class if it only applies to a new GDB
(e.g., creating GDBControl_7_3, if the feature applies to
GDB >= 7.3).
In this case, the timeout applies to all GDB versions
I believe (although a different default timeout value could
make sense for different GDBs).
You can add the feature in both GDBControl_7_0 and GDBControl
or directly in AbstractMIControl which is a base class for
all others.
