strip: move into core

As discussed at the 5.2 sprint, replace strip extension by a core
command, debugstrip.  Obviously, the extension stays for backwards
compatibility.

As an implementation note, I moved the strip file as is into core,
which is not done elsewhere, AFAIK. I could have inlined it into
debugcommands, but that doesn't sound great.
