Bug 1860947 - Add ReleaseData and string buffer AddRef and Release methods to the irrelevant signature list

[amccreight]

nsStringBuffer:: is still on the prefix list, but I don't actually see any instances of it besides AddRef and Release, so I'll leave it alone.

Thanks for the pull request! Here are some signature changes caused by this PR. Do they look like what you'd expect?

Crash id: 210f59f6-ed83-4f4d-a244-f53d90240521
Original: mozilla::StringBuffer::Release
New:      nsTSubstring<T>::Finalize | nsTSubstring<T>::~nsTSubstring | mozilla::MemoryMapping::~MemoryMapping

Same?:    False

Crash id: 64286038-e57b-4d54-97c7-3a7870240516
Original: nsStringBuffer::AddRef | nsTSubstring<T>::Assign | mozilla::dom::BlobSet::AppendUTF8String
New:      nsTSubstring<T>::Assign | mozilla::dom::BlobSet::AppendUTF8String
Same?:    False

I also noticed that there are crash reports with nsStringBuffer:: in the signature that are neither nsStringBuffer::AddRef nor nsStringBuffer::Release, e.g.

• https://crash-stats.mozilla.org/report/index/a985127b-84d9-4bea-bfa3-3f2f00240516
• https://crash-stats.mozilla.org/report/index/101fd758-0b9a-416a-bfaf-784900240518

The signatures of these reports will be left unchange by this PR.

If this is what you expect, the PR looks good to me.

Yes, that all looks fine to me. Thanks.

The other string buffer methods seem to be very rare so I think that's okay.
