Merge #14105: util: Report parse errors in configuration file
ed2332aeffb071a3404be9cff8f9fb8a81a9fbfb test: Add test for config file parsing errors (MarcoFalke)
a66c0f78a941968340f030911765a84219908c4d util: Report parse errors in configuration file (Wladimir J. van der Laan)

Pull request description:

  Report errors while parsing the configuration file, instead of silently ignoring them.

      $ src/bitcoind -regtest
      Error reading configuration file: parse error on line 22: nodebuglogfile, if you intended to specify a negated option, use nodebuglogfile=1 instead
      $ src/bitcoind -regtest
      Error reading configuration file: parse error on line 22: sdafsdfafs
      $ src/bitcoind -regtest
      Error reading configuration file: parse error on line 24: -nodebuglogfile=1, options in the configuration file must be specified without leading -
