Simon Giesecke ad01a10a3b Bug 1634281 - Use nsTHashMap instead of nsDataHashtable. r=xpcom-reviewers,necko-reviewers,jgilbert,nika,valentin
Note that this patch only transforms the use of the nsDataHashtable type alias
to a directly equivalent use of nsTHashMap. It does not change the specification
of the hash key type to make use of the key class deduction that nsTHashMap
allows for in some cases. That can be done in a separate step, but requires more
attention.
