Update license comments and added SPDX license identifiers

Previously, the only information about the specific version of GPL
was present in the README and individual source files mentioned only
GPL alone.

Let us update all copyright comments to explicitly say "GPL v2+"
and also include the machine readable SPDX license identifier.

libpci: Add new internal function pci_generic_scan_domain()

Function pci_generic_scan() scans PCI domain 0. This new function
pci_generic_scan_domain() scans specified PCI domain number.

libpci: generic: Implement SUBSYS also for PCI_HEADER_TYPE_BRIDGE

Subsystem ids for PCI Bridges are stored in extended capability
PCI_CAP_ID_SSVID.

libpci: generic: Implement CLASS_EXT and SUBSYS support

PCI_FILL_SUBSYS is implemented only for PCI_HEADER_TYPE_NORMAL and
PCI_HEADER_TYPE_CARDBUS like in lspci.

Simplified pci_fill_info() and friends

Previously, we kept track of which fields were already filled, which
was quite brittle.

Now we keep only the set of already known fields in struct pci_dev.
We check if the current field is needed against this information.

Not only this simplifies the whole thing, but it also enables future
back-ends to call pci_fill_info() recursively as needed.

Library: Big cleanup of pci_fill_info()

There was a lot of minor issues in the implementation of the fill_info
call-back in various back-ends. Most importantly, semantics of pci_dev->
known_fields was not formally defined and it was implemented inconsistently.

We now define known_fields as the set of fields which were already
obtained during the lifetime of the pci_dev. We never consider known
fields which are not supported by the back-end. All fields which are
unsupported by either the back-end, the OS, or the particular device,
are guaranteed to have sensible default values (0 or NULL). Also, bit
masks are always unsigned except for the signature of pci_fill_info()
which should be preferably kept stable.

All back-ends and the pci_generic_fill_info() function have been changed
to follow this semantics.

In the sysfs back-end, we read as few attributes as possible during
device initialization, so applications which use pci_get_dev() are not
slowed down unnecessarily.

In the Hurd back-end, we also respect the buscentric mode.

Added library functions for accessing PCI capabilities.

Coding style cleanup: `for(...)' wants a space.

Get rid of bzero().

Add and use PCI_FILL_CLASS.

Include file splits and namespace cleanups.

(pci_generic_scan_bus): Added work-around for devices with
discontiguous numbering of functions. This is already present in the Linux
kernel for several years, but I forgot to update pciutils as well.

Changed all my email addresses to [email protected].

Merged in AIX port.

Various PCIutils changes accumulated over last two weeks:

o Use `long' instead of `long long' for PCI addresses on Alpha.
o Synchronized header declarations with PCI specs rev. 2.2.

Various PCIutils changes accumulated over last two weeks:

o Use `long' instead of `long long' for PCI addresses on Alpha.
o Synchronized header declarations with PCI specs rev. 2.2.
o lspci: Dump all capabilities defined in PCI 2.2.
o lspci: Even htype1 has a capability list.
o lspci: Mask out bottommost 2 bits of capability pointers as required
by the specs.
o Added overall support for reporting of region sizes (needs support
in the kernel, but I've already sent a patch to Linus).
o pci_fill_info() returns a bitmask of what it suceeded to read (reading
of sizes can fail if the kernel doesn't support it).
o Some new IDs.

pciaddr_t which is an integer type capable of holding a PCI address.

o lspci scan mode: Don't dump functions 1--7 when scanning a real
multi-function device. (Several devices don't decode function bits at all).

o Few pci.ids additions.

Added `bus mapping mode' (-M) which scans the whole configuration space
to find devices hiding behind misconfigured or misdesigned bus bridges.
This is intended only for debugging purposes and it's available only to root
as it can crash several well-known buggy chips.

Add missing final argument to a->debug() call.

BTW, how do you add a __attribute__ ((format (printf, 1, 2))) to a function
pointer? Bugs like these would show up much sooner...

Rewrote the PCI Utilities. All PCI configuration space access has been
moved to a library which supports multiple access mechanisms: the current
/proc/bus/pci one, direct port access (needed for debugging of kernel
PCI code and as a nice side-effect this makes pciutils work with 2.0
kernels, although only for root) and reading of configuration dumps.

This has been released as version 1.99.2-alpha. For detailed description
of changes, see the ChangeLog.

Can anybody test it on non-PC architectures, please? (Especially if you
have any 64-bit card.)
