[PATCH 00/27] Add missing copyright information to many files

[Keith Packard]

I'm attempting to upload a version of newlib to Debian and have
discovered many files are missing copyright information. This makes it
difficult to create an accurate record of information for the package.

I built a tool to dig through GIT history to automatically associate
copyright and license information to new files where possible, and to
assign just copyright information from git author information where
there was no licensing data in history.

In a few cases, I went back to pre-git historical versions of the
repository to figure out the licensing and copyright status.

With these patches applied, I now have complete copyright information
for all of the source code built into the library, I'm missing copyrights for
some documentation and a couple of build scripts.
