Split out a more generic debugnet(4) from netdump(4)
Debugnet is a simplistic and specialized panic- or debug-time reliable datagram transport. It can drive a single connection at a time and is currently unidirectional (debug/panic machine transmit to remote server only).
It is mostly a verbatim code lift from netdump(4). Netdump(4) remains the only consumer (until the rest of this patch series lands).
The INET-specific logic has been extracted somewhat more thoroughly than previously in netdump(4), into debugnet_inet.c. UDP-layer logic and up, as much as possible as is protocol-independent, remains in debugnet.c. The separation is not perfect and future improvement is welcome. Supporting INET6 is a long-term goal.
Much of the diff is "gratuitous" renaming from 'netdump_' or 'nd_' to 'debugnet_' or 'dn_' -- sorry. I thought keeping the netdump name on the generic module would be more confusing than the refactoring.
The only functional change here is the mbuf allocation / tracking. Instead of initiating solely on netdump-configured interface(s) at dumpon(8) configuration time, we watch for any debugnet-enabled NIC for link activation and query it for mbuf parameters at that time. If they exceed the existing high-water mark allocation, we re-allocate and track the new high-water mark. Otherwise, we leave the pre-panic mbuf allocation alone. In a future patch in this series, this will allow initiating netdump from panic ddb(4) without pre-panic configuration.
No other functional change intended.

sys/dev: further 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.

Clean up MD pollution of bus_dma.h:
--Remove special-case handling of sparc64 bus_dmamap* functions. Replace with a more generic mechanism that allows MD busdma implementations to generate inline mapping functions by defining WANT_INLINE_DMAMAP in <machine/bus_dma.h>. This is currently useful for sparc64, x86, and arm64, which all implement non-load dmamap operations as simple wrappers around map objects which may be bus- or device-specific.
--Remove NULL-checked bus_dmamap macros. Implement the equivalent NULL checks in the inlined x86 implementation. For non-x86 platforms, these checks are a minor pessimization as those platforms do not currently allow NULL maps. NULL maps were originally allowed on arm64, which appears to have been the motivation behind adding arm[64]-specific barriers to bus_dma.h, but that support was removed in r299463.
--Simplify the internal interface used by the bus_dmamap_load* variants and move it to bus_dma_internal.h
--Fix some drivers that directly include sys/bus_dma.h despite the recommendations of bus_dma(9)
