New release candidate - 4.2.3

I've uploaded a 4.2.3-RC1 to Sourceforge this morning. It is 4.2.2 plus a few bugfixes and minor enhancements:

• Time-out code changed to use clock_gettime() with CLOCK_MONOTONIC
• Bugfix for hobbitd/hobbitd_worker communication going out-of-sync resulting in "garbled data" being logged and worker modules stopping.
• NCV module now works with negative numbers.
• Several bugfixes in DNS lookup code - could lead to crashes when performing DNS tests.
• Switch to C-ARES 1.6.0 - drop support for older versions.
• Run more TCP tests in parallel by not waiting for very slow connections to complete before starting new ones.
• Added "hostlist" web utility for spreadsheet-reporting of the hosts in Hobbit.

Give it a spin, and let me know if there are any problems. If not, I'll give it the official blessing to become 4.2.3 later this week.

Regards, Henrik
