Adopt Linux Foundation's guidance on copyrights

Adopt the Linux Foundation guidance [1] on copyright notice formats to
avoid meaningless and frequent updates to source files. It omits the
year range and gathers all contributors under a generic "The
[project-name] Contributors" term, which avoids the need for each
company to add their own copyright notice.
