Modify the NFS clients and the NLM so that the NLM can be used by both clients. Since the NLM uses various fields of the nfsmount structure, those fields were extracted and put in a separate nfs_mountcommon structure stored in sys/nfs/nfs_mountcommon.h. This structure also has a function pointer for a function that extracts the required information from the mount point and nfs vnode for that particular client, for information stored differently by the clients.

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.
