libdevinfo: Avoid false positives for the root0 sentinel value

Previously, a NULL pointer value was used to request the root0 device
at the top of the device tree. However, this meant that resource
ranges from a rman with a NULL device pointer were annotated as being
owned by root0 instead of being unowned. Switch to a different value
for root0's sentinel to avoid the clash.

Since this is an ABI change, bump the SHLIB_MAJOR for libdevinfo to 7.

lib: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified 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.

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.
