Log Message:
lint: in code from included files, print stack trace

Previously, the standard NetBSD build generated several lint warnings in
lhash.h from OpenSSL, without providing any hint as to which file
actually included that header.  In cases like these, lint now interprets
the line number information in the preprocessor output from GCC to
reconstruct the exact include path to the file in question.

The program check-expect.lua had to be rewritten almost completely since
it assumed that all diagnostics would come from the main file.  In all
existing tests, this was true, but these tests did not cover all cases
that occurred in practice.  Now it records the complete location of the
diagnostic instead of just the line number.
