    AX_CODE_COVERAGE: fix invalid chars in testname
    
    There was a warning about invalid characters in the testname from
    lcov: anything except letters, digits and the underscore causes
    this. So replace such characters with underscores (lcov does this
    anyway if we don't).
    
    Needs to either call $(subst ) for each undesired character or
    needs to execute a system command because GNU make does not
    provide regular expressions. Chose here to implement characters
    individually. Currently only strips dots and dashes, but these
    should be the most common culprits.

    AX_CODE_COVERAGE: add BRANCH_COVERAGE variable
    
    Add a new CODE_COVERAGE_BRANCH_COVERAGE variable that can be used
    to provide --rc lcov_branch_coverage=[01] options to lcov and
    --rc genhtml_branch_coverage=[01] options to genhtml. These may be
    desirable to the user since the default for branch coverage changed
    in some "recent" lcov version.
    
    This is achieved by adding a LCOV_SHOPTS variable (for SHared
    OPTionS) to the default LCOV_OPTIONS one. And the filtering call of
    lcov gets a symmetric LCOV_RMOPTS variable (which is currently
    empty).
    
    In addition, ensure that all LCOV_{SHOPTS,OPTIONS,RMOPTS} and
    GENHTML_OPTIONS have a corresponding _DEFAULT variable: this became
    desirable here because of the new defaults for LCOV_SHOPTS and
    GENHTML_OPTIONS; the LCOV_RMOPTS_DEFAULT is there only for
    symmetry.
