Locate AR using standard macro

The RETURN macro unconditionally returns so there is no chance to "continue".

The variable Left is supposed to hold only a positive quantity and was
being passed into functions that accept only size_t as input causing coverity
to throw a fit. Using a size_t type for Left works just fine.
Negative Returns, found by coverity.

per_put_few_bits should be checked for errors.
Checked return, fund by coverity.

On the previous line we return if cb is Null, so testing cb is worthless.
Dead code, found by coverity.

Link asn1c/tests with libasn1cskeletons.a in order to improve
skeletons coverage. When the skeleton files are copied the lcov will
report coverage for each copy separatly.

To generate the code coverage report you need gcov and lcov installed
and then execute

 ./configure --enable-code-coverage
 make check-code-coverage
