The new StaticPrefs machinery means that StylePrefs can be removed.
Note that this approach mirrors all static prefs into Rust, but I have only
updated structs.rs for the prefs that Stylo uses.

Currently VarCache prefs are setup in two parts:
- The vanilla pref part, installed via a data file such as all.js, or via an
API call.
- The VarCache variable part, setup by an Add*VarCache() call.
Both parts are needed for the pref to actually operate as a proper VarCache
pref. (There are various prefs for which we do one but not the other unless a
certain condition is met.)
This patch introduces a new way of doing things. There is a new file,
modules/libpref/init/StaticPrefList.h, which defines prefs like this:
> VARCACHE_PREF(
> "layout.accessiblecaret.width",
> layout_accessiblecaret_width,
> float, 34.0
> )
This replaces both the existing parts.
The preprocessor is used to generate multiple things from this single
definition:
- A global variable (the VarCache itself).
- A getter for that global variable.
- A call to an init function that unconditionally installs the pref in the
prefs hash table at startup.
C++ files can include the new StaticPrefs.h file to access the getter.
Rust code cannot use the getter, but can access the global variable directly
via structs.rs. This is similar to how things currently work for Rust code.
Non-VarCache prefs can also be declared in StaticPrefList.h, using PREF instead
of the VARCACHE_PREF.
The new approach has the following advantages.
+ It eliminates the duplication (in all.js and the Add*VarCache() call) of the
pref name and default value, preventing potential mismatches. (This is a real
problem in practice!)
+ There is now a single initialization point for these VarCache prefs.
+ This avoids need to find a place to insert the Add*VarCache() calls, which
are currently spread all over the place.
+ It also eliminates the common pattern whereby these calls are wrapped in a
execute-once block protected by a static boolean (see bug 1346224).
+ It's no longer possible to have a VarCache pref for which only one of the
pieces has been setup.
+ It encapsulates the VarCache global variable, so there is no need to declare
it separately.
+ VarCache reads are done via a getter (e.g. StaticPrefs::foo_bar_baz())
instead of a raw global variable read.
+ This makes it clearer that you're reading a pref value, and easier to
search for uses.
+ This prevents accidental writes to the global variable.
+ This prevents accidental mistyping of the pref name.
+ This provides a single chokepoint in the code for such accesses, which make
adding checking and instrumentation feasible.
+ It subsumes MediaPrefs, and will allow that class to be removed. (gfxPrefs is
a harder lift, unfortunately.)
+ Once all VarCache prefs are migrated to the new approach, the VarCache
mechanism will be better encapsulated, with fewer details publicly visible.
+ (Future work) This will allow the pref names to be stored statically, saving
memory in every process.
The main downside of the new approach is that all of these prefs are in a
single header that is included in quite a few places, so any changes to this
header will cause a fair amount of recompilation.
Another minor downside is that all VarCache prefs are defined and visible from
start-up. For test-only prefs like network.predictor.doing-tests, having them
show in about:config isn't particularly useful.
The patch also moves three network VarCache prefs to the new mechanism as a
basic demonstration. (And note the inconsistencies in the multiple initial
values that were provided for
network.auth.subresource-img-cross-origin-http-auth-allow!) There will be
numerous follow-up bugs to convert the remaining VarCache prefs.

- The first two SYNTAX HINTS are wrong, and citing the syntax is more useful
than specifying a single example of what isn't allowed.
- The sentence about #ifdefs is wrong. (#ifdefs appear all throughout, and

All prefs that need to be sent to a new content process are now put into the
shared memory segment, and they are identified by the pref name instead of an
index into a list. The old IPC used at process startup (in XPCOMInitData) is
removed.
Benefits:
- It removes the need for the early prefs list
(dom/ipc/ContentProcesses.{h,cpp}) and the associated checking, which is ugly
and often trips people up (e.g. bug 1432979, bug 1439406).
- Using prefnames instead of indices fixes some fragility (fixing bug 1419432).
- It fixes the problem of early prefs being installed as unlocked default
values even if they are locked and/or have user values.

The compartment-per-addon code was added so that we could segregate at least
some of the code from system-privileged add-ons into tagged compartments, even
when it ran in browser windows. That allowed us to apply certain special
behavior to them, such as enabling e10s shims, and to track some performance
characteristics.
The only remaining chrome-privileged add-ons now are system add-ons controlled
by us, and the shim system and per-compartment performance metrics are gone,
it no longer serves a purpose.

uim is an old IM which uses key snooper to listen to key events rather than
via filter key event API which should be called by applications. It's still
used by Debian 9.x, so, we still need to support this.
Unfortunately, we cannot detect if uim actually uses key snooper because it's
switch by build option of uim. Currently, Debian builds uim as using key
snooper. So, we should assume uim uses key snooper always. On the other
hand, somebody *might* use uim built as not using key snooper, so, let's
decide if uim uses key snooper with new pref,
"intl.ime.hack.uim.using_key_snooper", but its default should be true.
Note that ibus and Fcitx also have the mode to use key snooper (perhaps for
backward compatibility with uim). However, it's not enabled in default
settings and even if it's enabled, Firefox is in whitelist in the default
settings of them for stop using key snooper. Therefore, we don't need to
support key snooper mode for them unless we'll get some requests to
support their key snooping mode.

On Android, GeckoEditableSupport has already dispatched eKeyDown event and
eKeyUp event even during composition. I.e., the pref which will be enabled
by bug 354358 has already been set to true only on Android.
On the other hand, GeckoEditableSupport does not dispatch them if content
listens to "input", "compositionstart", "compositionupdate" or
"compositionend". So, different from the other platforms, we need additional
pref to make the new behavior behind pref.
Therefore, this patch adds a new pref,
"intl.ime.hack.on_any_apps.fire_key_events_for_composition", to override
existing "intl.ime.hack.on_ime_unaware_apps.fire_key_events_for_composition"
pref. And sets mKeyCode and mKeyNameIndex of the dummy KeyboardEvents to
NS_VK_PROCESSKEY and KEY_NAME_INDEX_Process.

Historically we built all our binaries in directories in the objdir, then
symlinked them into dist/bin. Some binaries needed to be copied instead
so that certain relative path lookups work properly, so we resorted to
sprinkling `NSDISTMODE=copy` around Makefiles.
This change makes it so we build PROGRAMs (not any other sort of targets)
directly in dist/bin instead. We could do the same for our other targets
with a little more work.
There were several places in the tree that were copying built binaries to
some other place and needed fixup to match the new location of binaries.
On Windows pdb files are left in the objdir where the program was
originally linked. symbolstore.py needs to locate the pdb file both to
determine whether it should dump symbols for a binary and also to copy
the pdb file into the symbol package. We fix this by simply looking for
the pdb file in the current working directory if it isn't present next
to the binary, which matches how we invoke symbolstore.py.
