new-bus: Remove the 'rid' and 'type' arguments from BUS_RELEASE_RESOURCE

The public bus_release_resource() API still accepts both forms, but
the internal kobj method no longer passes the arguments.
Implementations which need the rid or type now use rman_get_rid() or
rman_get_type() to fetch the value from the allocated resource.

spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD

The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch

Remove isa_devclass from ISA bus drivers.

sys: general adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

Convert rman to use rman_res_t instead of u_long

Summary:
Migrate to using the semi-opaque type rman_res_t to specify rman resources. For
now, this is still compatible with u_long.

This is step one in migrating rman to use uintmax_t for resources instead of
u_long.

Going forward, this could feasibly be used to specify architecture-specific
definitions of resource ranges, rather than baking a specific integer type into
the API.

This change has been broken out to facilitate MFC'ing drivers back to 10 without
breaking ABI.

Retire isa_setup_intr() and isa_teardown_intr() and use the generic bus
versions instead. They were never needed as bus_generic_intr() and
bus_teardown_intr() had been changed to pass the original child device up
in 42734, but the ISA bus was not converted to new-bus until 45720.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Allow device hints to wire the unit numbers of devices.
- An "at" hint now reserves a device name.
- A new BUS_HINT_DEVICE_UNIT method is added to the bus interface. When
determining the unit number of a device, this method is invoked to
let the bus driver specify the unit of a device given a specific
devclass. This is the only way a device can be given a name reserved
via an "at" hint.
- Implement BUS_HINT_DEVICE_UNIT() for the acpi(4) and isa(4) bus drivers.
Both of these busses implement this by comparing the resources for a
given hint device with the resources enumerated by ACPI/PnPBIOS and
wire a unit if the hint resources are a subset of the "real" resources.
- Use bus_hinted_children() for adding hinted devices on isa(4) busses
now instead of doing it by hand.
- Remove the unit kludging from sio(4) as it is no longer necessary.

MFp4:

Make the ISA bus keep track of more PNP details. Plus a minor style
fix while I'm here. More could be done here, but except for some SBCs
that don't have ACPI, there's limited value to anybody in doing so.

- Import the HEAD csup code which is the basis for the cvsmode work.

o break newbus api: add a new argument of type driver_filter_t to

Get rid of #ifdef for legacy system. Move that into the MD code.
Export minimal symbols to allow this to happen.

A few style(9) changes before more extensive changes:
o u_intXX_t -> uintXX_t
o use 8 character tabs
o proper wrapping
o return (value);

No need to declare M_ISADEV here.

Change isa_get/set_flags() to device_get/set_flags().

This represents essentially a complete rewrite of the ISA PnP code. The
new system is integrated with the ISA bus code more cleanly and allows
the future addition of more enumerators such as PnPBIOS and ACPI.

This commit also enables the new pcm driver since it is somewhat tied to
the new PnP code.
