We use the SPDX Unique Lincense Identifiers here; these are available
at [2].

Note: From the legal point of view, this patch is supposed to be only
a change to the textual representation of the license information,
but in no way any change to the actual license terms. With this patch
applied, all files will still be licensed under the same terms they
were before.

Note 2: The apparent difference between the old "COPYING" and the new
"Licenses/gpl-2.0.txt" only results from switching to the upstream
version of the license which is differently formatted; there are not
any actual changes to the content.

Note 3: There are some recurring questions about linense issues, such
as:
    - Is a "All Rights Reserved" clause a problem in GPL code?
    - Are files without any license header a problem?
    - Do we need license headers at all?

The following excerpt from an e-mail by Daniel B. Ravicher should help
with these:

|
| That is a very fact specific analysis and could be different across the
| various files.  However, if the contributor could reasonably be expected
| to have known that the project was licensed GPLv2 or later at the time
| she made her contribution, then a reasonably implication is that she
| consented to her contributions being distributed under those terms.
|
| > - Do such files need any clean up, for example should we add GPL

|
| If the project as a whole is licensed under clear terms, you need not
| identify those same terms in each file, although there is no harm in
| doing so.

|
| It is not a conflict to grant a license and also reserve all rights, as
| implicit in that language is that you are reserving all "other" rights
| not granted in the license.  Thus, a file with "Licensed under GPL, All
| Rights Reserved" would mean that it is licensed under the GPL, but no
| other rights are given to copy, modify or redistribute it.
