This ping will be sent as soon as an update is ready to be applied, after
it's downloaded. This is currently enabled but protected behind the
'toolkit.telemetry.updatePing.enabled' preference.

It schedules the ping to be sent on new profiles after 30 minutes
from the Firefox startup. The ping is eventually sent at shutdown
if the scheduled time wasn't reached.
To reliably prevent sending the ping more than once, the "session-state.json"
file is used to keep track of the "sent" state.
The "new-profile" ping is protected behind a pref, disabled by default
in this patch.

Currently we hand over a crash ping to the pingsender via a pipe; if the
pingsender fails to send the ping we rely on the CrashManager assembling and
sending one instead. Since the crashmanager is not aware of whether the ping
was sent or not this causes duplication on the server side. To solve this
problem we save the ping to disk instead, read it from the pingsender and
delete the file only if the ping was sent. In this scenario the CrashManager
will know that a ping was already sent and will not send a new one.
This patch removes all the code used to deal with pipes between the telemetry,
crashreporter and pingsender code and also tries to cut down the amount of
platform-specific code we have in this machinery.

This also adds a 'Date' header and a custom version header for the pingsender.
It additionally makes sure that the Windows implementation fails when HTTP error
codes are returned from the server.
