This patch allows to configure the amount of RAM that GDB monitor should
preserve for itself. The configuration syntax looks as follows:
<start name="gdb_monitor">
<resource name="RAM" quantum="1G"/>
<config>
<target name="noux">
<preserve name="RAM" quantum="2M"/>
...
</config>
</start>
Fixes #190.
