Subject: Bug 1487082 - Resolve potential for build bustage regarding bad
 implicit conversion constructors

* Part 1: make conversion CTORs explicit.
  Minor tweaks to conform with new(ish) static analysis rule which flags up implicit single-argument conversion constructors.
* Part 2: fix a couple of double-mRefCnt declaration errors.
* Part 3: Fix unsafe use of NS_ConvertASCIItoUTF16().
