Instead of some functions operating with hex strings,
and others using bytes, this consolidates most things to use bytes.
This mainly focuses on bitcoin.py and transaction.py,
and then adapts the API usages in other files.
Notably,
- scripts,
- pubkeys,
- signatures
should be bytes in almost all places now.
```
$ ./electrum/scripts/quick_start.py
Traceback (most recent call last):

AssertionError: already started
```
just the sanity check added in 6ac3f84095
The following exceptions should be expected:
FileNotFoundError: given wallet path does not exist
StorageReadWriteError: given file is not readable/writable or containing folder is not writable
InvalidPassword: wallet requires a password but no password or an invalid password was given
WalletFileException: any internal wallet data issue. specific subclasses can be caught separately:
- WalletRequiresSplit: wallet needs splitting (split_data passed in Exception)
- WalletRequiresUpgrade: wallet needs upgrade, and no upgrade=True was passed to load_wallet
- WalletUnfinished: wallet file contains an action and needs additional information to finalize. (WalletDB passed in exception)
Removed qml/qewalletdb.py
This patch also fixes load_wallet calls in electrum/scripts and adds a qml workaround for dialogs opening and closing so
fast that the dialog opened==true property change is missed (which we need to manage the dialog/page stack)
This reverts commit dc6c481406 as it introduced its own issue:
while add_address was running on one thread, synchronizer._reset could be running on another,
and by the time the "enqueue" coro would run, it would use a new add_queue and
addr would not be in requested_addrs anymore...

AddressSynchronizer.add_address called synchronizer.add, which would only
schedule adding the addr to the Synchronizer in the next event loop iter.
If during that time, the synchronizer called adb.set_up_to_date(True),
the wallet would falsely believe and advertise itself as up_to_date
(as the wallet would see wallet.synchronize not creating new addresses,
and adb (via synchronizer) telling it is up_to_date).
Moments later, the synchronizer._add_address is finally executed and
up_to_date=False propagates out synchronizer->adb->wallet.
Note: this was causing a weird flake8 error on CI. Presumably due to CI running flake8 via py3.7.

Previously all the interfaces used either "t" or "s".
Now the network only tries to use "s" for all interfaces, except for
the main interface, which the user can manually specify to use "t".
(so e.g. if you run with "--server localhost:50002:t", the main server will use "t",
but all the rest will use "s")
The few other cases that used SimpleConfig.get_instance() now
either get passed a config instance, or they try to get a reference
to something else that has a reference to a config.
