Remove the assumption that pnp_register_driver() returns the number of devices
claimed. Returning the count is unreliable because devices may be hot-plugged
in the future.
This changes the convention to "zero for success, or a negative error value,"
which matches pci_register_driver(), acpi_bus_register_driver(), and
platform_driver_register().

Also use the PnP functions to start/stop the devices during the suspend so
that drivers will not have to duplicate this code.

This patch contains the following possible cleanups:
- make needlessly global code static
- #if 0 the following unused global function:
- core.c: pnp_remove_device
- #if 0 the following unneeded EXPORT_SYMBOL's:
- card.c: pnp_add_card
- card.c: pnp_remove_card
- card.c: pnp_add_card_device
- card.c: pnp_remove_card_device
- card.c: pnp_add_card_id
- core.c: pnp_register_protocol
- core.c: pnp_unregister_protocol
- core.c: pnp_add_device
- core.c: pnp_remove_device
- pnpacpi/core.c: pnpacpi_protocol
- driver.c: pnp_add_id
- isapnp/core.c: isapnp_read_byte
- manager.c: pnp_auto_config_dev
- resource.c: pnp_register_dependent_option
- resource.c: pnp_register_independent_option
- resource.c: pnp_register_irq_resource
- resource.c: pnp_register_dma_resource
- resource.c: pnp_register_port_resource
- resource.c: pnp_register_mem_resource
Note that this patch #if 0's exactly one functions and removes no
functions. Most it does is the #if 0 of EXPORT_SYMBOL's, so if any modular
code will use any of them, re-adding will be trivial.
Modular ISAPnP might be interesting in some cases, but this is more legacy
code. If someone would work on it to sort all the issues out (starting
with the point that most users of __ISAPNP__ will have to be fixed)
re-enabling the required EXPORT_SYMBOL's won't be hard for him.

Seems pointless to require .c files to test CONFIG_PNP_DEBUG and
conditionally define DEBUG before including <linux/pnp.h>. Just test
CONFIG_PNP_DEBUG directly in pnp.h.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
