Added autogeneration of cinfo.c with memory capabilities
...
Also fixed a bug with configurator in that the containers
were not sorted properly and consequently an already filled
in container was getting overwritten by the new one.
modified: config/configuration.py

Added newer platform files.
...

drivers, platforms, arch, subarch etc.

New files are an exact copy of pb926 files, but will help in testing different
configurations and compilations.

Generalize the configuration processing so that the top-level SConstruct only processes the ARCH symbol and prepares the PLATFORM and SUBARCH entries so as to write the config.h. Everything is now entered in the environment so the SConscript files can be responsible fo rthe processing.

Capabilities for quantitative resources working.
...
Status:
- Capability initialization is a bit hacky with dummy current etc.
- All container caps belong to the pager
- Tasks refer to their pager's capabilities for mutex allocation - Hacky.
- Kernel container keeps quantitative caps and memory caps in separate lists - Hacky.
These will all evolve and get fixed.

Capability accounting for quantitative capabilities - First part done.
...
Need to make sure accounting charges correct containers during init.
Therefore kernel resource spending must also be accounted for.

Clean up to kernel code, Added `used' field to capabilities

used for resource accounting over the capability.

Pager virtual address pool bookkeeping added for all pager virtual addresses
...
Previously virt_to_phys/phys_to_virt macros were used such that they did a
blind offset translation for creating a pager internal virtual address for
user mappings.
This is now changed such that a properly bookkeeped virtual address pool is
used which will avoid any clashes on the virtual space.
