Official WebKit no longer supports Mac 10.14. However, since
this system is still very much in use, we want to be able to
keep it running for a while.
This patch adds a new browser that we would compile and maintain
specifically for Mac 10.14: `deprecated-webkit-mac-10.14`. This
browser is a clone of Webkit r1443 that is the last known revision
to compile on Mac 10.14.
As we move on, we're free to modify this browser however we want,
backporting important patches.

This fixes a bug where the script was creating a folder with a new line
symbol in its name. As a result, Windows was failing to remove this
folder, and Chromium Windows BuildBot was failing to even initialize
checkout.
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
