[boost] [1.54.0] [log] Permission to merge to release

Hi, I'd like to ask for permission to merge Boost.Log to the release branch. All test issues are resolved, although some MinGW testers haven't run the tests for 2 weeks and haven't updated the report. RDC-VC10 tester also didn't clean the previous test results so the report is not showing the actual results (other MSVC testers are green). The util_dynamic_type_dispatcher and util_static_type_dispatcher rows should be ignored, these tests were renamed to util_dynamic_type_disp and util_static_type_disp, respectively.
