This commit un-deprecates DeprecatedString, and repurposes it as a byte
string.
As the null state has already been removed, there are no other
particularly hairy blockers in repurposing this type as a byte string
(what it _really_ is).
This commit is auto-generated:
$ xs=$(ack -l \bDeprecatedString\b\|deprecated_string AK Userland \
Meta Ports Ladybird Tests Kernel)
$ perl -pie 's/\bDeprecatedString\b/ByteString/g;
s/deprecated_string/byte_string/g' $xs
$ clang-format --style=file -i \
$(git diff --name-only | grep \.cpp\|\.h)
$ gn format $(git ls-files '*.gn' '*.gni')
These classes are used as-is in all chromes. Move them to LibWebView so
that non-Serenity chromes don't have to awkwardly reach into its headers
and sources.
When the `FilteringOptions::SortByScore` flag is set, filtered indices
are sorted by match score in descending order, meaning the most
relevant results should appear first.
The default behavior of FilteringProxyModel is unchanged.
