Add a patch to prevent a crash in firefox

The crash occurs when opening HTML videos, only if firefox has been
compiled against rust-1.52.0 or higher.

Fix a lot of wrong indents in changelog (and one in firefox)

121 The mach build system (Python scripts) can be somewhat unreliable: if
122 the build fails and reports an Error, it can still return a status of
123 success, causing a scripted build to try to install (which does not rerun
124 the build), fail during the preparations for installing, but still exit
125 with a status of success. Also, on occasion it may limit itself to only
126 running one set of jobs - that will make the build take about 3 times as
127 long as running with four sets of jobs.

435 That directory is used for a (probably random) telemetry identifier.

538 That was on x86_64, on i686 the syscall number is 54. To allow this
539 syscall, in <command>about:config</command> change
540 <command>security.sandbox.content.syscall_whitelist</command> to 16
541 (or 54 if using i686).

545 If you use <command>pulseaudio</command> in a Desktop Environment, it
546 might already be started by that DE. But if it is not, although
547 firefox-57 managed to start it, firefox-58 did not. If you run
548 <command>firefox</command> from a term and this problem is present,
549 trying to play sound will
550 encounter error messages warning <literal>Can't get cubeb
551 context!</literal>

555 The fix for this is to close firefox, start pulseaudio to check it
556 does start (if not, read the information on Configuring in <xref
557 linkend="pulseaudio"/>) and restart firefox to check it is working.
558 If it now works, add the following to your <filename>~/.xinitrc</filename>:
559<phrase revision="sysv">
560<literal>pulseaudio --verbose --log-target=syslog&amp;</literal></phrase>
561<phrase revision="systemd">
562<literal>pulseaudio --verbose --log-target=journald&amp;</literal></phrase>
563 (unfortunately, on some systems this does not work).

567 You may wish to use multiple profiles within firefox. To do that, invoke
568 firefox as <command>firefox --ProfileManager</command>. You can also
569 check which profile is currently in use from
570 <command>about:profiles</command>.

574 Although WebRender (using the GPU for compositing) is not used by
575 default, it now appears to work well on supported hardware (ATI, Nvidia
576 and Intel GPUs with Mesa-18 or later. For an explanation, please see
577 <ulink
578 url="https://hacks.mozilla.org/2017/10/the-whole-web-at-maximum-fps-how-webrender-gets-rid-of-jank/">hacks.mozilla.org</ulink>.
579 The only downside seems to be that on a machine with limited RAM it might
580 use more RAM.

584 To check if WebRender is being used, look in about:support. In the Graphics
585 section Compositing will either show 'Basic' (i.e. not in use) or
586 'WebRender'. To enable it, go to about:config and change gfx.webrender.all
587 to True. You will need to restart firefox.

591 It may be useful to mention the processes from firefox which can appear in
592 <command>top</command> - as well as firefox itself, there may be multiple
593 Web Content processes, and now an RDD Process (Remote Data Decoder) which
594 appears when playing web videos encoded with av1 (libdav1d). If WebRender
595 has been enabled, a GPU Process will also appear when firefox has to
596 repaint (e.g. scrolling, opening a new tab, or playing a video).
