This adapts the arbiter to a bug fixed in libpciaccess. We were relying on
the library to probe devices and map regions but it's the arbiter who should
do it.
* pci-arbiter/pcifs.c:
* create_fs_tree(): probe the device to find regions and rom
* pci-arbiter/func_files.c:
* io_region_file(): map region on the first access attempt

* pci-arbiter/pcifs.c:
* create_dir_entry: Add memset()
* create_fs_tree: Remove memset()

This patch removes all embedded pciaccess code from the arbiter
and instead uses the external pciaccess library.
* pci-arbiter/Makefile:
* Remove pci_access.c and x86_pci.c from the sources.
* pci-arbiter/func_files.c:
* io_config_file: Use a harcoded PCI config size.
* read_rom_file:
Grab the full rom first, then return the
requested amount.
* pci-arbiter/main.c:
* main: Call create_fs_tree() w/o pci_sys.
Since it's not part of the translator anymore.
* pci-arbiter/netfs_impl.c:
* netfs_attempt_read:
Send pci_device_cfg_read() as the read op.
* netfs_attempt_write:
Send pci_device_cfg_write() as the write op.
* pci-arbiter/pci-ops.c:
* S_pci_conf_read: Call libpciaccess' pci_device_cfg_read().
* S_pci_conf_write: Call libpciaccess' pci_device_cfg_write().
* S_pci_get_dev_rom:
Set rom.base_addr to zero for the moment, until
libpciaccess esposes it properly.
* pci-arbiter/pci_access.c: Deleted
* pci-arbiter/pci_access.h: Deleted
* pci-arbiter/pcifs.c:
* create_fs_tree:
Remove the pci_sys parameter.
Use libpciaccess' iterator.
Use a hardcoded config space size.
* pci-arbiter/pcifs.h: Definitions for changes in pcifs.c.
* pci-arbiter/x86_pci.c: Deleted.
* pci-arbiter/x86_pci.h: Deleted.

snprintf guarantees to add a trailing \0, so there is no need to add one
* pci-arbiter/pcifs.c (create_fs_tree): Give whole buffer to snprintf.

* pci-arbiter/pcifs.c:
* create_dir_entry:
Limit to NAME_SIZE-1 when calling strncpy().
Finish entry->name with '\0'.
* create_fs_tree:
memset() to 0 the directory entry.
Limit to NAME_SIZE-1 all calls to
snprintf() and strncpy().
