The SRI hash at the beginning of ScriptLoadRequest::mScriptBytecode is left
uncompressed because ScriptLoader::OnIncrementalData() tries to decode it
as soon as enough data is read (instead of waiting until OnStreamComplete()).
ScriptLoader writes the length of the uncompressed bytecode to the buffer
to make it easy for ScriptLoadHandler to allocate an buffer of the right size
to decompress the bytecode.
These changes are based on the bytecode compression implemented for WASM in
dom/fetch/FetchUtil.cpp.

This is used when we explicitly don't want to load cached bytecode. It is
better served by a separate flag in the request than a state.

Module bytecode should use different MIME type, to avoid mixing up script/module
bytecodes for single JS file.
This patch adds a static method that simply returns the current bytecode MIME
type.
The later patch adds a new MIME type for module bytecode and modify the
ScriptLoader::BytecodeMimeTypeFor method to return corresponding MIME type.

We can reduce the size of the SSO by removing the element slot entirely, and instead retrieve the element through a callback function. The callback will take in the value in the private slot of the SSO, which is either a LoadedScript* (from the browser) or a JSObject* (from the shell). In addition, this removes the requirement of having a script dom element ready when parsing a JS script which can open up new opportunities for performance.

The inclusions were removed with the following very crude script and the
resulting breakage was fixed up by hand. The manual fixups did either
revert the changes done by the script, replace a generic header with a more
specific one or replace a header with a forward declaration.
find . -name "*.idl" | grep -v web-platform | grep -v third_party | while read path; do
interfaces=$(grep "^\(class\|interface\).*:.*" "$path" | cut -d' ' -f2)
if [ -n "$interfaces" ]; then
if [[ "$interfaces" == *$'\n'* ]]; then
regexp="\("
for i in $interfaces; do regexp="$regexp$i\|"; done
regexp="${regexp%%\\\|}\)"
else
regexp="$interfaces"
fi
interface=$(basename "$path")
rg -l "#include.*${interface%%.idl}.h" . | while read path2; do
hits=$(grep -v "#include.*${interface%%.idl}.h" "$path2" | grep -c "$regexp" )
if [ $hits -eq 0 ]; then
echo "Removing ${interface} from ${path2}"

This requires replacing inclusions of it with inclusions of more specific prefs
files.
The exception is that StaticPrefsAll.h, which is equivalent to StaticPrefs.h,
and is used in `Codegen.py` because doing something smarter is tricky and
suitable for a follow-up. As a result, any change to StaticPrefList.yaml will
still trigger recompilation of all the generated DOM bindings files, but that's
still a big improvement over trigger recompilation of every file that uses
static prefs.
Most of the changes in this commit are very boring. The only changes that are
not boring are modules/libpref/*, Codegen.py, and ServoBindings.toml.

To reduce the attack surface in early test for BinAST, add a preference to
restrict the hosts that Firefox accepts BinAST file from.
The preference is turned on by default (BinAST itself is turned off by
default for now), and the list contains hosts which is going to be used in
early test.
For hosts not listed in the list, Firefox doesn't send BinAST MIME-Type in
Accept field, and doesn't handle BinAST file in case the server returns
BinAST file.
