When downloading a file, we check for existing mime types and construct
a new one if it's unrecognized. Mime types have a flag,
alwaysAskBeforeHandling, that determines whether the unknown content
type dialog should be opened before handling the file. Before bug
1733492, the default value for that flag was simply true. Since the new
downloads flow is intended to avoid unnecessary steps, the default value
was changed to the inverted value of the new downloads panel
improvements pref. This patch adds a new pref that the mime info
constructor will read in configuring the flag's value. If the
improvements pref is not enabled, then the flag will be true, so the UCT
dialog will open. If the improvements pref is enabled, then it'll use
the value of the new pref. Also add a an interface for the pref to the
about:preferences UI, and automatically migrate a false value for
browser.download.improvements_to_download_panel to a true value for this
pref. I'm updating some tangentially related test files since they
happen to be touched slightly by this change. Strictly speaking they
would still work, but if the pref value was somehow changed from the
default they would fail.

Without this, changing to add_setup in individual test files causes the tasks to be reordered, which causes tests to fail.
I also had to adjust an enterprise policy test that was expecting setup tests to run inbetween tasks.

The migration from "always ask" to "save to disk" is not wanted in Thunderbird.
Rather than flip the preference (which may have further side effects and will go away some day), I would rather just stop the migration code from running in Thunderbird.

multipart/x-mixed-replace loads don't start a new load for parts other than the first,
they just call OnStartRequest/OnStopRequest for every part. The nsDocShell code was
trying to set the active entry to the loading entry for these loads, but because we
never started a new load after the first part, the loading entry would be null and we'd
just clear the active entry. history.replaceState would then try to replace the active
entry, but finding none it would just add a new one.

This is a mechanical change which was performed by a script based on the
contents of direct_call.py, and then manually checked over to fix
various rewriting bugs caused by my glorified sed script. See the
previous part for more context on the change.
