Add common InitConfig function to deduplicate bitcoind and bitcoin-qt code reading config files and creating the datadir. There are a few minor changes in behavior: - In bitcoin-qt, when there is a problem reading the configuration file, the GUI error text has changed from "Error: Cannot parse configuration file:" to "Error reading configuration file:" to be consistent with bitcoind. - In bitcoind, when there is a problem reading the settings.json file, the error text has changed from "Failed loading settings file" to "Settings file could not be read" to be consistent with bitcoin-qt. - In bitcoind, when there is a problem writing the settings.json file, the error text has changed from "Failed saving settings file" to "Settings file could not be written" to be consistent with bitcoin-qt. - In bitcoin-qt, if there datadir is not accessible (e.g. no permission to read), there is an normal error dialog showing "Error: filesystem error: status: Permission denied [.../settings.json]", instead of an uncaught exception
