The MOZ_MUST_USE macro is defined as clang's and gcc's nonstandard __attribute__((warn_unused_result)). Now that we compile as C++17 by default (bug 1560664), we can replace MOZ_MUST_USE with C++17's standard [[nodiscard]] attribute.
The [[nodiscard]] attribute must precede a function declaration's declaration specifiers (like static, extern, inline, or virtual). The __attribute__((warn_unused_result)) attribute does not have this order restriction.

This patch was generated by running:
```
perl -p -i \
-e 's/^(\s+)([a-zA-Z0-9.]+) = NS_ConvertUTF8toUTF16\((.*)\);/\1CopyUTF8toUTF16(\3, \2);/;' \
-e 's/^(\s+)([a-zA-Z0-9.]+) = NS_ConvertUTF16toUTF8\((.*)\);/\1CopyUTF16toUTF8(\3, \2);/;' \
$FILE
```
against every .cpp and .h in mozilla-central, and then fixing up the
inevitable errors that happen as a result of matching C++ expressions with
regexes. The errors fell into three categories:
1. Calling the convert functions with `std::string::c_str()`; these were
changed to simply pass the string instead, relying on implicit conversion
to `mozilla::Span`.
2. Calling the convert functions with raw pointers, which is not permitted
with the copy functions; these were changed to invoke `MakeStringSpan` first.
3. Other miscellaneous errors resulting from over-eager regexes and/or the
replacement not being type-aware. These changes were reverted.

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 ${path2}"
grep -v "#include.*${interface%%.idl}.h" "$path2" > "$path2".tmp
mv -f "$path2".tmp "$path2"

Sub classes of `nsITextControlElement` are only `HTMLInputElement` and
`HTMLTextAreaElement`. And both base class is
`nsGenericHTMLFormElementWithState`. Therefore, we can make
`nsITextControlElement` inherit `nsGenericHTMLFormElementWithState` and
make `HTMLInputElement` and `HTMLTextAreaElement` inherit
`nsITextControlElement`. Then, we can get rid of a lot of QI between
`nsINode`/`nsIContent`/`Element` and `nsITextControlElement` (and note that
some of them in a hot path).
Additionally, this patch renames `nsITextControlElement` to
`mozilla::TextControlElement`.

This prepares nsFrameLoader for replacing mBrowserParent and mBrowserBridgeChild
with a common interface by making special case code use a getter method instead
of direct access.

Summary: Really sorry for the size of the patch. It's mostly automatic
s/nsIDocument/Document/ but I had to fix up in a bunch of places manually to
add the right namespacing and such.
Overall it's not a very interesting patch I think.
nsDocument.cpp turns into Document.cpp, nsIDocument.h into Document.h and
nsIDocumentInlines.h into DocumentInlines.h.
I also changed a bunch of nsCOMPtr usage to RefPtr, but not all of it.
While fixing up some of the bits I also removed some unneeded OwnerDoc() null
checks and such, but I didn't do anything riskier than that.
Adding the Places* files into unified sources pushed the
unified sources into a situation that exposed a strangely
large number of errors. This seems to be the minimum set of
changes I could make to resolve all of the issues.
