Adds the use of solib-search-path as done in the CDT (by filling the Shared Library subtab in the debugger tab of the launch).
Also adds the use of auto-solib-add as in the CDT.
Currently, DSF launches gdb with a <file> argument, which tells gdb where the
executable file and the symbols are. This is potentially restrictive to
someone wanting to extend gdb.
This change removes the <file> argument to gdb and uses -file-exec-file and
-file-symbol-file commands to set this parameter in the FinalLaunchSequence.
This has the exact same effect, but allows to easily override these commands by
using a tailored FinalLaunchSequence.
Moved the packages org.eclipse.dd.gdb.* to
org.eclipse.dd.gdb.internal.provisional.*
since it's expected that these classes are likely to need substantial
changes in not too distant future.
The point of having an org.eclipse.dd.gdb.launch plugin was to allow other people to ignore this plugin and not have the standard DSF launches appear.
However, the DSF launch classes can still be useful to those people as they can be extended. Therefore, the launch code should not be in org.eclipse.dd.gdb.launch, but put back in org.ecipse.dd.gdb
