power_daemon: Refactor to handle multiple exported power devices.

- Each PowerMonitor now exports a set of descriptors rather than
only a single one. This allows e.g. PowerButtonMonitor to watch
multiple possible button event sources rather than one.

This gets power button working again on some hardware that exports
multiple ACPI power buttons, but offers no obvious way to determine
which one is actually active/being used. In the long term though, it'd
be nice to have a well-defined kernel power event interface that an app
could subscribe to, rather than having to watch individual devfs
descriptors.

Thanks to tqh and korli for advice/review.

Merge branch 'gcc_syslibs'

* From now on, the gcc-specific system libraries (libgcc, libsupc++ and
libstdc++) are provided by separate packages built along with gcc:
- gcc_syslibs contains the shared libraries (libgcc_s.so, libsupc++.so and
libstdc++.so)
- gcc_syslibs_devel contains the static libraries and both c++ and gcc
headers
The shared libraries now make proper use of symbol versioning and there
are version-specific symlinks
* The buildsystem has been adjusted to no longer use the libraries and
headers from the cross-compiler, but use the ones provided by the
above-mentioned packages. The only exception is that the 32-bit libraries
required for the bootloader of the x86_64 architecture are still taken
from the cross-compiler.

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.

Use the new private roster API to shutdown.
Maybe we should have a confirmation alert the first time ?
Btw, the power_button driver should really implement select() or some other non-polling mechanism, it sux having to waste cpu.

Added the beginnings of our power management daemon. Currently does nothing except tell the roster to shut down when you press the power button (in conjuction with acpi_button, of course). Eventually will do things like display low power warnings, spin down hard disks, and display the requisite power info deskbar replicant.
