The old and new behaviour is as follows:
1. "pyinstaller" case: portable `.exe`, other `.exe`s with `--portable`, and `.dmg` with `--portable`
- uses `$PWD`
- note that when you double-click the portable `.exe` on Windows, `$PWD` is set to the parent folder, i.e. the datadir gets put next to the `.exe`
2. appimage `--portable`
- was broken (see https://github.com/spesmilo/electrum/issues/5551)
- (CHANGED NOW to) uses `$PWD`
3. git clone
- next to `run_electrum`
4. unpacking `tar.gz` and running locally from it
- next to `run_electrum`
5. `pip install *.tar.gz`, and calling "electrum --portable" from terminal
- used python's user script directory
- `~/.local/bin/electrum_data`
- `$VIRTUAL_ENV/bin/electrum_data`
- (CHANGED NOW to) uses `$PWD`
That is, we now almost always put the datadir in `$PWD`,
except for the local source case, where we put it next to `run_electrum`.
The "appimage" case (2) is now fixed.
The only breaking change is re case 5 which previously behaved completely
unintuitively and most likely not in a useful way.

pyinstaller 4.3 changed the value of `__file__`.
This change makes our behaviour independent of that pyinstaller change
(we always behave like old versions of pyinstaller).
fixes https://github.com/spesmilo/electrum/issues/7729
regression was introduced by b5951adc29
- rename `is_bundle` to `is_pyinstaller` (no semantic changes, just to clearer name)
- define `is_appimage`
- add comment to explain `is_local`
- its value is the same as before (but more explicit definition)
- define `is_git_clone`, and restrict DeprecationWarnings to that case
aiorpcx 0.20 changed the behaviour/API of TaskGroups.
When used as a context manager, TaskGroups no longer propagate
exceptions raised by their tasks. Instead, the calling code has
to explicitly check the results of tasks and decide whether to re-raise
any exceptions.
This is a significant change, and so this commit introduces "OldTaskGroup",
which should behave as the TaskGroup class of old aiorpcx. All existing
usages of TaskGroup are replaced with OldTaskGroup.

* Remove check for sign with privkey in init_cmdline
* Add with_privkey and with_wallet variants of signtransaction command
* Add unit tests for signtransaction_with_privkey and signtransaction_with_wallet commands
Previously, during early-startup (until configure_logging(config) is
called in run_electrum),
- the stderr log handler lost all log messages below warning level, and
- the file log handler lost all log messages regardless of log level
We now instead start buffering log messages in memory as soon as
electrum.logging is imported. The buffer is dumped into the
stderr and file log handlers when they are fully set up, and then
the buffer is discarded (and the temporary log handler is removed).
Note that messages are not logged until configure_logging() is called.
Previously WARNING/ERROR messages would get logged immediately to stderr,
but not anymore. This was changed so that the order of the log messages
can be kept intact. (if we log WARNINGs immediately, but need to delay
INFOs until the config is available, messages would either be out of order
or alternatively there would be duplicates)
Relatedly, we now follow the recommendation of the python docs re
logging for libraries [0]: we try to only configure logging if running via
run_electrum (the main script) and not when e.g. a 3rd party script
imports electrum.

Note that newer aiorpcx started requiring python 3.8, so we cannot use
the latest versions, until we too bump the min python version to 3.8.
We should not do that until debian stable ships python 3.8.
Also, new aiorpcx introduced some API changes which we will need to
adopt, so even if the user locally has recent enough python, we need
old aiorpcx atm.

When the app is started, the password is checked against all
wallets in the directory.
If the test passes:
- subsequent wallet creations will use the same password
- subsequent password updates will be performed on all wallets
- wallets that are not storage encrypted will encrypted
on the next password update (even if they are watching-only)
This behaviour is restricted on Android, with a 'single_password' config variable.
Wallet creation without password is disabled if single_password is set
When running kivy on Linux desktop,
running from git clone, `./run_electrum -g kivy` worked,
but `pip install -e .; electrum -g kivy` did not.
This was due to the relative paths using cwd as base.
see #6835
Previously an unhandled exception in the main script could cause the main thread to die
but the process to hang, as the event loop thread would keep running.

Since #6014, pyaes is not really needed anymore.
As we currently require either one of pycryptodomex or cryptography,
even if pyaes is available, it will not be used.
We could strip it out completely from crypto.py...
In any case, pyaes is still pulled in by some hw wallet dependencies indirectly;
but the core library no longer depends on it.
previously, if GUI-related imports raised, the GUI would not start
but the process would not exit (e.g. asyncio event loop would go on)

ImportError: DLL load failed while importing QtGui: The specified module could not be found.
Load DLLs from inner 'electrum' dir instead of '.dlls'.
To make it consistent with where we expect libsecp256k1 (.dll/.so) be.
(note that while in case of libsecp we specifically already search the main dir,
without this change, other DLLs such as libusb or libzbar would not be found there)
Python 3.8 changed where DLLs are searched for.
see https://docs.python.org/3/whatsnew/3.8.html#bpo-36085-whatsnew
This potentially affect our binaries when we start shipping python 3.8+, however that is not being addressed here. This commit simply addresses the usecase of running from source, on Windows, using python 3.8.
On older Python, a user could build/obtain DLLs and place them anywhere on the system %PATH%, however this no longer works with py3.8, as %PATH% is no longer checked.
With py3.8, instead, we now check if there is a folder named '.dlls' in the top-level project directory, and if so, register that as an additional search path.
A user who wants to run Electrum from source on Windows using python 3.8 or later, with their custom DLLs, should manually create the '.dlls' folder and put their DLLs there. If they also want to switch between e.g. python 3.7 and 3.8, they should also include '.dlls' in the system %PATH%.
When using Electrum, interesting DLLs include at least libsecp256k1.dll, libusb-1.0.dll, libzbar-0.dll.
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.
(see lnsweep, qt/qrcodewidget, qt/qrtextedit)
e.g. when interacting with hw wallets (e.g. signmessage)
it does not make sense to time out
also, str(e) of some exceptions such as TimeoutError is ""...
- commands are async
- the asyncio loop is started and stopped from the main script
- the daemon's main loop runs in the main thread
- use jsonrpcserver and jsonrpcclient instead of jsonrpclib
