These timeouts will ensure that we don't block the Safe Browsing update thread
for too long when we encounter slow or bad network conditions.

When starting up, SafeBrowsing.jsm will try to use DBService to add testing entries. Meanwhile,
listmanager will request StreamUpdater to download lists with a random initial delay.
The requests that listmanager issue to StreamUpdater will be queued up
if DBserve is busy and will be retried when StreamUpdater is notified that
the previous update is complete. However, in some edge cases,
the queued requests may not be processed until the next update request from listmanager.
For example, SafeBrowsing.jsm calls DBService.beginUpdate at t0 and the update is
complete at t1. If listmanager sends all requests via StreamUpdate between t0 and t1,
they will all be queued up and no further request can trigger the queued ones.
So in this patch I add a timer to re-trigger FetchNextRequest() in case StreamUpdater is not
notified the previous update is complete.

The probes keep track of V2 and V4 server response to update and getHash
request. The probes are keyed by provider

mTelemetryProvider might be empty if |CancelUpdate| is called during update.
In that scenario, the call flow will look like:
CancelUpdate -> UpdateError -> DownloadDone -> set mTelemetryProvider to empty ->
OnStartRequest -> record telemetry with empty key.
So in this patch, move mTelemetryProvider.Truncate() to OnStopRequest.

nsTArray::AppendElement may cause memory reallocation if out of capacity.
In nsUrlClassifierStreamUpdater::FetchNextRequest(), we take the reference of
the first element of mPendingRequests and pass its member as reference to
DownloadUpdate(), where mPendingRequests.AppendElement will be called.
If the AppendElement in DownloadUpdate() causes realloc, the reference
becomes dangling.
The most efficient fix is to "move" the reference's (i.e. request)
member variables to DownloadUpdate() but I think in this case we can just
take the value from the array and pass it around with no given that the
array element contains simply a couple of strings and pointers.

This function is an infallible alternative to nsIURI::GetSpec(). It's useful
when it's appropriate to handle a GetSpec() failure with a failure string, e.g.
for log/warning/error messages. It allows code like this:
nsAutoCString spec;
uri->GetSpec(spec);
printf("uri: %s", spec.get());
to be changed to this:
printf("uri: %s", uri->GetSpecOrDefault().get());
This introduces a slight behavioural change. Previously, if GetSpec() failed,
an empty string would be used here. Now, "[nsIURI::GetSpec failed]" will be
produced instead. In most cases this failure string will make for a clearer
log/warning/error message than the empty string.

Bug 1297961 (part 1b) - More GetSpecOrDefault() additions. r=hurley.
I will fold this into part 1 before landing.

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.
