* pci-arbiter/device_map.h:
* pci-arbiter/device_map.c:
* New function: device_map_rom
* Copies the whole rom in the arbiter space.
* pci-arbiter/pcifs.h:
* struct pcifs_dirent:
* New field to store the mapping address for each device rom.
o pci-arbiter/func_files.h:
* pci-arbiter/func_files.c:
* read_rom_file:
* Retrieves the rom contents from the local space instead of
libpciaccess.
* pci-arbiter/netfs_impl.c:
* netfs_attempt_read:get_filemap_region
* Update call to read_rom_file.
* get_filemap_region:
* Uses the old code at netfs_get_filemap to get a proxy to
the device memory region.
* get_filemap_rom:
* Returns a proxy to the locally mapped device rom.
* netfs_get_filemap:
* Checks the requested file to map and calls get_filemap_rom,
get_filemap_region or returns en error.

Use a internal array of pointers instead
* pci-arbiter/device_map.h:
* Update device_map_region() prototype
* Now it receives an output address as parameter
* pci-arbiter/device_map.c:
* Update device_map_region() definition to match the new prototype
* Support for legacy mappings
* When the base address is lower than 1 mb
* pci-arbiter/func_files.c:
* pci-arbiter/netfs_impl.c:
* Update calls to device_map_region to match the new prototype
* Use the internal array of pointers instead of region->memory
* pci-arbiter/pcifs.h:
* struct pcifs_dirent: Declare the internal array of pointers

* pci-arbiter/Makefile:
* Add device_map.c to sources
* pci-arbiter/device_map.c:
* pci-arbiter/device_map.h:
* New module for device mapping
* Relies on libpciaccess mapping methods
* pci-arbiter/func_files.c:
* io_region_file(): Use the new device mapping module
* pci-arbiter/netfs_impl.c:
* Implements netfs_get_filemap():
* Uses the device mapping module to map the region to the
arbiter space
* Calls the kernel RPC vm_region_create_proxy() to obtain the
memory object proxy
* Only region files are mapped for now
