Eric Rahm 75c4bebb79 Bug 1165515 - Part 13-2: Replace usage of PRLogModuleLevel and PR_LOG_*. rs=froydnj
This is straightforward mapping of PR_LOG levels to their LogLevel
counterparts:
  PR_LOG_ERROR   -> LogLevel::Error
  PR_LOG_WARNING -> LogLevel::Warning
  PR_LOG_WARN    -> LogLevel::Warning
  PR_LOG_INFO    -> LogLevel::Info
  PR_LOG_DEBUG   -> LogLevel::Debug
  PR_LOG_NOTICE  -> LogLevel::Debug
  PR_LOG_VERBOSE -> LogLevel::Verbose

Instances of PRLogModuleLevel were mapped to a fully qualified
mozilla::LogLevel, instances of PR_LOG levels in #defines were mapped to a
fully qualified mozilla::LogLevel::* level, and all other instances were
mapped to us a shorter format of LogLevel::*.

Bustage for usage of the non-fully qualified LogLevel were fixed by adding
|using mozilla::LogLevel;| where appropriate.
