Propagating the mp4san new feature through all the layers of libsignal.
The feature allows seamless handling of transcoded MP4 files on Android, where multiple MDAT boxes (one per chunk of A/V streams) are first compounded and then passed to mp4san for format correction.
And expose an explicit setInvalidProxy, both for testing and in case
apps want to do their own connection-poisoning.
This makes it easier to be consistent about "if you try to set a proxy
that turns out not to be valid, the ConnectionManager should end up in
the invalid state until explicitly cleared", whether the validation is
done on the Rust side of the bridge or the app language side.
This takes a full set of components describing the connection to a
proxy: a scheme, a host, and optionally a port and auth information.
The previous `setProxy(String, u16)` signature is still available for
Signal TLS proxies in particular, but now we have the flexibility to
support other kinds of proxies as well.
This takes a full URL (as a string) to use as a proxy. The previous
`setProxy(String, int)` signature is still available for Signal TLS
proxies in particular, but now we have the flexibility to support
other kinds of proxies as well.
Validates a backup frame-by-frame, bypassing the encryption,
compression, and integrity-checking layers. Intended for use during an
export the user is waiting for, such as linking a new device.
This matches the split that has already happened in the TypeScript and
Swift APIs. For now, both AuthChat and UnauthChat are wrappers around
the same type, a fully general chat::Chat, but we expect to eventually
split that into authenticated and unauthenticated variants as well. At
that point we can consider whether the common implementation here is
still pulling its weight.
This means they'll be shipped to clients, but still filtered out of
the device builds on Android (via having two separate libraries on
disk) and iOS (by not being included in non-simulator builds). The
biggest benefit of this is dropping the :android:makeTestJniLibraries
step for running libsignal's Android tests.
