Support reading the new style of neverclaim output by Spin 6.24+.

* src/neverparse/neverclaimparse.yy, src/neverparse/neverclaimscan.ll:
Allow transitions between do..od, recognize atomic and assert.
* src/neverparse/parsedecl.hh: Pass the error_list to the lexer.
* src/tgbatest/neverclaimread.test: Add a test case.
