55d9ff6a66 config: make -Werror optional and off by default
Allow end users to build the code even if, for example, warnings are
added with new compilers versions.

-Werror is still enforced for automated builds.

c02b179490 Remove year from copyright headers.
Also add a space between Copyright and (c).

The copyright year can be determined using git metadata.

Also remove the duplicated "All rights reserved." - every instance of
this line already has a corresponding "All rights reserved" immediately
below it, except for examples/ioat/kperf/kmod/dma_perf.c, where I have
added it manually.

Performed using this command:

git ls-files | xargs sed -i -e 's/Copyright(c) \(.*\) Intel Corporation. All rights reserved./Copyright (c) Intel Corporation./'

Some compilers automatically define _FORTIFY_SOURCE to a different

9ea5194634 build: simplify dependency generation
Modern GCC and Clang versions can generate .d files without needing the
complex sequence of sed scripts that we currently use.

Also adjust the .o rule so the .d file is regenerated if it gets
deleted.

Also make the .o depend on all of the Makefile fragments in
$(MAKEFILE_LIST) so that it is rebuilt if the Makefile is changed.

7cb4463dc5 build: use -std=gnu99 rather than -std=gnu11
We don't use any C11-specific features, and switching to C99 will allow
us to support older versions of GCC.

In particular, the version of GCC used by Travis CI is too old to
support -std=gnu11.
