For example, if the source code is located in a directory called "spdk",
don't print the "spdk/" prefix on all of the directories.

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./'

The normal CU_ASSERT_FATAL macro calls a function that is not marked as
noreturn, so static analyzers (e.g. scan-buid) can't figure out that
fatal asserts are really fatal.
Add a wrapper macro that calls abort(), which the analyzer can determine
does not return.

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.

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.

This forces the ELF loader to resolve all relocations immediately at
load time rather than allowing lazy binding.
Therefore the loader can make the GOT (global offset table) read-only
once the relocations are complete during the loading process.
