Browsers require particular xcode versions to be installed on the host
machine to produce successful build.
This patch starts using explicit xcode versions for all mac browser
builds.
When Firefox decides to perform an http->https redirect based on HSTS
information, it issues an "internal" redirect and cancels the http request.
Since there is no response for the http request, we forge 307 redirect
in this case, following Chromium lead.
The relevant code is in nsHttpChannel::StartRedirectChannelToHttps.
- to read post data of requests, we have to read stream
- to restore the stream later on, we have to rewind it back
- however, if the stream is large enough, it cannot be rewound back
This patch starts cloning post data streams if possible to avoid
back-rewinding them later on.

After this roll, we no longer require our custom `onFrameLocationChanged` instrumentation
since gecko now fixed the `NOTIFY_LOCATION` behavior so that it works
for same-document navigations inside iframes.
browser(firefox): properly initialize debugging pipe on windows
Firefox on Windows has 2 launch modes:
- default: a special "launcher process" is used to start browser as a
sub-process
- non-default: browser process starts right away
Firefox has a logic to detect how successful was the use of the
launcher process to do self-recovery when things go wrong. Namely:
- when attempting to use launcher process, firefox records a timestamp
of the attempt beginning
- once the launcher process successfully launches browser sub-process,
firefox records another timestamp of the completion
On a new launch, firefox checks what timestamps are present. If there's
a timestamp that signifies start of launcher process, but no successful
timestamp, it decides that last "launcher process" use was not
successful and falls back to launching browser right away.
When launching 2 firefox processes right away, the first process
uses attempts to use launcher process and records the first timestamp.
At the same time, the second instance sees the first timestamp and
doesn't see the second timestamp, and falls back to launching browser
right away. Our debugging pipe code, however, does not support
non-launcher-process code path.
This patch adds support for remote debugging pipe in case of
non-launcher-process startup.
Drive-by:
- disable crashreporter altogether
- remove stray dcheck that breaks firefox debug compilation
- disable compilation of firefox update agent
- do not use WIN32_DISTRIB flag unless doing full builds since
it kills incremental compilation

browser(firefox): ensure detachedFromTarget is always sent
LinkedBrowser can throw when removing listeners in PageTarget.dispose,
and that prevents BrowserHandler from sending Browser.detachedFromTarget.
Using a try-catch seems good enough.
Currently, browser.version() returns `83.0`, whereas launching firefox
with `--version` flag returns `83.0b3`. This patch alings protocol's
`Browser.version()` with flag output.
Somehow, we get WebProgress state changes when worker is loaded
with a blob url. This messes up frame navigation detection.
Luckily, it's easy to filter out non-document state changes.
As Joel noticed recently, MessageManager in firefox doesn't guarantee
message delivery if the opposite end hasn't been initialized yet. In
this case, message will be silently dropped on the ground.
To fix this, we establish a handshake in SimpleChannel to make sure that
both ends are initialized, end buffer outgoing messages until this
happens.
Drive-by: serialize dialog events to only deliver *after* the
`Page.ready` protocol event. Otherwise, we deliver dialog events to the
unreported page.
We try to avoid closing firefox too early, fearing that this
might terminate clean shutdown sequence.
Usually we assume that `Browser.enable` is called before `Browser.close`
- however, this is not the case in certain tests. So we have to
ensure browser initialization in `Browser.close` as well.
In my local tests, this fixes the Firefox Pipe problem: it looks like
we were closing browser too quickly.
It looks like terminating browser when search service or addon manager is
not fully initialized results in a broken shutdown sequence. As of
today, this results in multiple errors in the browser STDERR. In future,
this might also result in browser stalling instead of terminating.
This starts awaiting search and addon manager termination.

Using WebProgressListener events works in all cases. Currently
used `pageshow` event will stop being emitted in future when loading
was stopped with `window.stop()` api.
