To facilitate easier management by users and to
follow generally accepted standards, this PR moves
the following all to user home directory, subdir
.joinmarket :
joinmarket.cfg file
wallets/ directory
logs/ directory
cmtdata/ directory
commitmentlist file
User can override location with --datadir option.
An info message is added on startup showing location.
The above commit introduces auto freezing for utxos below
a threshold, but erroneously auto freezes new utxos in
almost all cases because transactions are processed
multiple times (add_utxos handles this in the wallet).
The problem here is solved as with the same issue of
duplication in the logging of new transactions; we keep
track of new txids that arrive in the wallet and make
sure not to process the same txid twice.
Additionally, the setting of WalletService.used_addresses
is fixed. Test for this function is also fixed.
Closes#274. Utxos are disabled if they are sent
to a reused address, and are below a threshold
set by the value `max_sats_freeze_reuse` in the
`POLICY` section of the config file. If the value
is -1, such utxos are always frozen irrespective of
the value.
Users are prompted with a warning level logging message
on CLI and a popup on Joinmarket-Qt. Such disabled utxos
can of course be re-enabled by the existing methods.
Also adds test case for address reuse freezing function.
