Nicholas Nethercote c86dc10505 Bug 1380227 - Avoid many UTF16toUTF8 and UTF8toUTF16 conversions in nsStringBundle. r=emk.
Most of the names passed to nsIStringBundle::{Get,Format}StringFromUTF8Name
have one of the two following forms:

- a 16-bit C string literal, which is then converted to an 8-bit string in
  order for the lookup to occur;

- an 8-bit C string literal converted to a 16-bit string, which is then
  converted back to an 8-bit string in order for the lookup to occur.

This patch introduces and uses alternative methods that can take an 8-bit C
string literal, which requires changing some signatures in other methods and
functions. It replaces all C++ uses of the old methods.

The patch also changes the existing {Get,Format}StringFromName() methods so
they take an AUTF8String argument for the name instead of a wstring, because
that's nicer for JS code.

Even though there is a method for C++ code and a different one for JS code,
|binaryname| is used so that the existing method names can be used for the
common case in both languages.

The change reduces the number of NS_ConvertUTF8toUTF16 and
NS_ConvertUTF16toUTF8 conversions while running Speedometer v2 from ~270,000 to
~160,000. (Most of these conversions involved the string
"deprecatedReferrerDirective" in nsCSPParser.cpp.)
