Use git config --get-all user.name as an build author, if not available use
user@hostname.

This commit fixes all copyright notes, using "git blame" as a
reference.  For simple files I just added a 2-lines boilerplate about
being WR and GPL.

Some parts I left untouched:

  trivial-init and related files (unclear to me what this is,
  and pf-microcode.h is magic binary pfilter values).

  tools/lm32-etheruart: I don't know what this is and who the author is

  libsdbfs: this comes from another repo and I'd better not change it

  sfp_lib.h and hal_shmem.h: I lost track about the origin of this,
  among the several packages.

This doesn't change the behavior of any command, but adds revision.c
as a real source file rather than something created by make using
"echo ... > revision.c".  In any case, the file is recompiled
each time you call "make", so the date and time reflect the last
build.

However, this introduces CONFIG_DETERMINISTIC_BINARY (that nobody
sets at this point in time) to build a binary withouth __DATE__
and __TIME__ strings, so it is the same at every rebuild. See
next commit.
