AFAIK, neither GPL nor Apache license actually _require_ this. You may
have missed the "END OF TERMS AND CONDITIONS" markers when reading the
corresponding web pages.
1) I'm consulting https://www.apache.org/licenses/LICENSE-2.0
"You must cause any modified files to carry prominent notices stating
that You changed the files;"
This seems to suggest to add something like
Copyright 2017 m...@example.net
to the header of a source code file.
In APPENDIX: HOW TO APPLY THE APACHE LICENSE TO YOUR WORK
[https://www.apache.org/licenses/LICENSE-2.0#apply] there is the
boilerplate notice, and also if the text is not 100% clear, it seems
that it must be added to every source code file.
2) In https://www.gnu.org/licenses/gpl.html it says explicitely
"How to Apply These Terms to Your New Programs
[..]
attach the following notices to the program. It is safest to attach them
to the start of each source file to most effectively state the exclusion
of warranty; and each file should have at least the “copyright” line and
a pointer to where the full notice is found.
"
and then there is the usual boilerplate.
So for Apache and GPL the suggested way is attaching the usual
boilerplate header to every source code file. I'm not a lawyer but at
this point I suspect that the usual/suggested way is the same also for
BSD. Also because a file is a strong container of source code, and so it
is 100% clear who are the authors, and which license is applied to the
code.

- the AUTHORS (but not who made typos/small bug-fixes)
Yes, and a committee of lawyers that determine whether a given
contribution warrants adding its author to the source code file(s) plus
a dedicated group of developers that have nothing better to do but move
author lines from one source file to another when the code is
reshuffled. And an Oracle that remembers who wrote what and removes no
longer valid author entries as the code gets deleted. Oh, and do not
forget a small group of assistants that change all those duplicated
author emails when author employer changes (while following up with the
old employer for a permission to change competitorA.com emails to
competitorB.com emails in sources).</sarcasm>
- a short version of the license terms
There is no "short version" of GPL or Apache terms. What folks often put
in source code files is a reference to a document that contains the
actual license(s). It is up to each project to determine the exact text
of that reference, keeping various official recommendations (i.e., the
stuff _after_ TERMS AND CONDITIONS) and the number of applicable
licenses in mind.
Alex.
