Before the LIBPCI didn't probe device0 (AD16), the host bridge
drivers used bus=dev=func=0 to internally probe the host bridge's
target interface. Now that LIBPCI uses bus=dev=func=0 to access
device0, bus=0xff is introduced internally to identify the
host bridge target configuration space.

The old code used a limited PCI configuration library, which was
duplicated into LEON2 and LEON3 BSP pci.c together with respective
Host controller PCI interface.
The LEON2 BSP had support for AT697 PCI, and LEON3 for GRPCI PCI
Host controller. With this update new PCI Host drivers are added,
and all support the new generic PCI Library:
* AT697 PCI (LEON2 only)
* GRPCI (LEON2-GRLIB and LEON3)
* GRPCI2 (LEON2-GRLIB and LEON3)
* Actel PCIF GRLIB Wrapper (LEON3 only)
The LEON2 BSP is defined as big-endian PCI in bsp.h, since the
AT697 supports only big-endian PCI.

The PCI and RASTA versions of the uart, spacewire and 1553 drivers directly includes the c-file of the standard versions
of the drivers, but uses a macro to change the name of the driver register function. When the standard version is
used this function should be global, when it is included as part of the PCI and RASTA versions it should be local and
static.

+ libbsp/sparc/shared/include/pci.h was largely a copy of
an older version of the cpukit pci.h. Removed much of the
contents and included <rtems/pci.h>.
+ sparc/*/pci*.c - Move to <rtems/pci.h> required updating
to use uint32_t for dword accesses.
+ Rename PCI_MULTI_FUNCTION to PCI_HEADER_TYPE_MULTI_FUNCTION
+ Define PCI_HEADER_TYPE_MULTI_FUNCTION in cpukit pci.h and remove
PCI_MULTI_FUNCTION definitions in C files.
+ Move PCI_INVALID_VENDORDEVICEID definitions from various C files
to cpukit pci.h

Script does what is expected and tries to do it as
smartly as possible.
+ remove occurrences of two blank comment lines
next to each other after Id string line removed.
+ remove entire comment blocks which only exited to
contain CVS Ids
+ If the processing left a blank line at the top of
a file, it was removed.
