[Bug preprocessor/26857] New: Warning for absolute or dotted header paths

[mbland at google dot com]

Given that some build systems try to encapsulate system headers separately from
those found in /usr/include, primarily through careful arrangement of -I flags,
it would be helpful if there was a warning flag, let's call it
-Wstrict-header-path for now, which would signal when a source file tries to do
the following:

#include "/usr/include/sys/stat.h"
#include "../../../sys/stat.h"

Ian Lance Taylor has indicated to me that this could be done as a check on
fname in do_include_common in libcpp/directives.c.  I would be willing to
attempt a patch myself if this enhancement is accepted.

I've got a working patch for 4.1.0, including a test case, reviewed by Ian
Lance Taylor.  As soon as "our people" can work out an agreement with "your
people" over copyright assignment, I'll be sure to post it to this PR.

This has been in the back of my mind...  I'll get it ready soon.
