This transport IIUC is only used for the trezor emulator.
The default timeout is 10 seconds. Every time we enumerate hw devices,
we also enumerate trezor devices, including scanning for the udp transport.
For some reason, recently on Windows, sporadically, this scan keeps
hitting the timeout for me. Quite annoying, as I might not even be testing
trezor (and I am certainly not testing using the trezor emulator on Windows...),
but scanning to test other plugins.
Probably overkill to have a 10 sec timeout for contacting localhost anyway.
Since Electrum is not using TxRequestSerializedType.serialized_tx
we might ask the device not to serialize transactions
by setting SignTx.serialize=False
This flag is only present in trezorlib 0.13.4, so only users on that
version will benefit from the speedup.
However, we decided to keep the minimum required version to 0.13.0,
since the newer version is not strictly required.
e.g.

In the past, when creating payment requests, we keyed them by on-chain address,
and set/saved the msg of the request as label for the address.
Many places in the code were calling wallet.get_label(addr) with the expectation that
relevant payment requests are found and their message/description (if any) is considered.
wallet.get_label(key) is now made private, and instead the explicit non-polymorphic
wallet.get_label_for_{address,rhash,txid} alternatives should be used.
The keystore does not have a "client" field.
One is supposed to use the "get_client" method instead (the generic API is `plugin.get_client(keystore)`)
Remnants of old code.
I had a ledger nano S and a ledger nano S plus connected at the same time,
and the "id_"s were colliding resulting in weird behaviour. Multisig was pretty
much not usable with both devices connected simultaneously.
