Whenever a cache entry is accessed during a document load, eTLD+1 of the top level document is added to the entry's metadata. Number of accessing sites is also stored in cache index. So we know how many copies of each entry would we have if we did a first party isolation without data deduplication. The telemetry is sent every time we write 2GB to the cache and then the data is reset. Telemetry report ID is an identifier of the telemetry cycle and it's used to invalidate eTLD+1 hashes in all cache entries.

This patch adds content-type to metadata in cache entry and it is then propagated down to the cache index.

This patch changes the way we set and handle the preferred alternate data type.
It is no longer just one choice, but a set of preferences, each conditional
on the contentType of the resource.
For example:
var cc = chan.QueryInterface(Ci.nsICacheInfoChannel);
cc.preferAlternativeDataType("js-bytecode", "text/javascript");
cc.preferAlternativeDataType("ammended-text", "text/plain");
cc.preferAlternativeDataType("something-else", "");
When loaded from the cache, the available alt-data type will be checked against
"js-bytecode" if the contentType is "text/javascript", "ammended-text" if the contentType is "text/plain" or "something-else" for all contentTypes.
Note that the alt-data type could be "something-else" even if the contentType is "text/javascript".
The preferences are saved as an nsTArray<mozilla::Tuple<nsCString, nsCString>>.

When writing to alt-data output stream fails for whatever reason, we now try to
truncate alternative data and keep the original data instead of dooming the
whole entry. The patch also changes how is the predicted size passed to the
cache. Instead of a dedicated method it's now an argument of openOutputStream
and openAlternativeOutputStream methods which fail in case the entry would
exceed the allowed limit.
All the instances are converted as follows.
- nsSubstring --> nsAString
- nsCSubstring --> nsACString

* Add PAltDataOutputStream.ipdl to be able to open an OutputStream to the cache entry in the child process
* AltDataOutputStreamChild/Parent are Main Thread only for now.
* Adds methods for reading and writing alt-data to nsICacheInfoChannel.idl
* Keep a ref of the cache entry after OnStopRequest in case the consumer tries to open the alt-data output stream
