Use libstdc++, libsupc++ and libgcc from gcc_syslibs.

* Instead of faking libstdc++.so from libstdc++.a, use libstdc++.so
from the gcc_syslibs build feature for everything except x86_gcc2.
* Use libgcc_s.so from the gcc_syslibs build feature for everything but
x86_gcc2 (which still carries libgcc as part of libroot.so).
* Drop filtering of libgcc objects for libroot, as that is no longer
necessary since we're only using libgcc-as-single-object for libroot
with x86_gcc2, where the filtered object file doesn't exist. Should
the objects that used to be filtered cause any problems as part of
libgcc_s.so, we can always filter them as part of the gcc build.
* Use libsupc++.so from the gcc_syslibs build feature for everything but
x86_gcc2.
* Adjust all Jamfiles accordingly.
* Deactivate building of faked libstdc++.so for non-x86-gcc2. For
x86_gcc2, we still build libstdc++.so from the sources in the Haiku
source tree as part of the Haiku build .
* Put gcc_syslibs package onto the image, when needed.

More work towards hybrid support

* All packaging architecture dependent variables do now have a
respective suffix and are set up for each configured packaging
architecture, save for the kernel and boot loader variables, which
are still only set up for the primary architecture.
For convenience TARGET_PACKAGING_ARCH, TARGET_ARCH, TARGET_LIBSUPC++,
and TARGET_LIBSTDC++ are set to the respective values for the primary
packaging architecture by default.
* Introduce a set of MultiArch* rules to help with building targets for
multiple packaging architectures. Generally the respective targets are
(additionally) gristed with the packaging architecture. For libraries
the additional grist is usually omitted for the primary architecture
(e.g. libroot.so and <x86>libroot.so for x86_gcc2/x86 hybrid), so that
Jamfiles for targets built only for the primary architecture don't
need to be changed.
* Add multi-arch build support for all targets needed for the stage 1
cross devel package as well as for libbe (untested).

Added a few classes to the debug kit:
* BDebugMessageHandler: Interface with hooks for handling of debug messages.
* BDebugContext: Essentially a C++ wrapper for struct debug_context, with
handy methods for controlling a debugged team.
* BTeamDebugger: Proxy for a debugged team. Derived from BDebugContext.
* BDebugLooper: Wraps a main debug message loop. Any number of BTeamDebuggers
can be added and associated with BDebugMessageHandlers.

the respective trunk

Defined a simple file format to store debug event streams as generated by the
system profiling interface and added classes BDebugEvent{Input,Ouput}Stream for
reading/writing those files.

* Some refactoring: There are three ways to access the symbols of an image.
Formerly two were implemented in ImageFile (from file, via syscalls) and one
in SymbolLookup (via the debugger interface). Now there's a base class Image
and respective derived classes implementing those methods.
* Simplified SymbolIterator.
* Moved the classes into sub-namespace BPrivate::Debug.

* Introduced new header directory headers/private/system which is supposed
to contain headers shared by kernel and userland (mainly libroot).
* Moved quite a few private kernel headers to the new location. Split
several kernel headers into a shared part and one that is still kernel
private. Adjusted all affected Jamfiles and source in the standard x86
build accordingly. The build for other architectures and for test code
may be broken.
* Quite a bit of userland code still includes private kernel headers.
Mostly those are <util/*> headers. The ones that aren't strictly
kernel-only should be moved to some other place (maybe
headers/private/shared/util).

Added support for looking up symbols of other team to libdebug. The
debug_server uses this feature to print stack traces with symbols.



git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@13698 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added patch originally written by Ingo Weinhold:
- extended libdebug.so functionality to be able to get stack frames,
current instruction pointer, etc.
- changed the debug_server to be able to run as a simple BLooper - this
saves some trouble when the app_server dies
- the debug_server now prints out a stack crawl for the crashed team
(without symbols, though - for that data to be helpful you should
have a look at the loaded images (ie. where they start))
- the debug_server now also prints the team name when it kills it

Added the beginnings of a small private API for debug support.
Entirely implemented on top of the public <debugger.h> API, but more
convenient to use. Lives in a separate library libdebug.so.
