cmMakefile: return a backtrace

This allows backtraces to be fully controlled by the makefile rather
than externally (and makes changing how they are manipulated easier).
cmake: remove dummy backtraces for IssueMessage
genex: remove the need for backtraces

Rather than making dummy backtraces and passing them around, just make
backtraces optional.
backtrace: Convert to local paths in IssueMessage

This is the only place we care show the FilePath to the user, so defer
the expensive relative path calculation until here.

Improvement to coverage.py source file search algorithm

If the coverage.py source file is not found in the source directory, the build
directory is first searched before raising an error.

This is necessary because it is a valid workflow to build a Python package from
source, then install this package to a virtualenv that lives in the build
directory.  Tests will run against this deployed package and therefore the
covered source files will be found in a subdirectory of the build directory, and
not anywhere in the source directory.
