Make MockDevice behavior configurable

[danbim]

In order to test certain use cases (e.g. in benchmarks and unit tests) the MockDevice should provide different behaviors. Using the Map<String,String> configuration-parameter there should be the possibility to configure its behavior.

Parameters:

Option	Possible Values	Description
UART_LATENCY	any Integer	If set, the MockDevice will emulate UART latency of Integer.parseInt(arg) milliseconds
BOOT_MESSAGE	any String	If not null, the MockDevice prints this string to the outgoing data stream after it was reset
BOOT_MESSAGE_TYPE	"ascii" | "binary"	If "ascii" the string is modified to a byte array via String.toByteArray(), if "binary" the String is parsed using StringUtils.fromStringToByteArray()
HEARTBEAT_MESSAGE	any String	If not null, the MockDevice writes periodic heartbeat messages to the outgoing data stream (currently named aliveRunnable). The String passed is, depending on the value of HEARTBEAT_MESSAGE_TYPE, parsed and sent periodically as heartbeat message
HEARTBEAT_MESSAGE_TYPE	"ascii" | "binary"	If "ascii" the string is modified to a byte array via String.toByteArray(), if "binary" the String is parsed using StringUtils.fromStringToByteArray()
HEARTBEAT_MESSAGE_RATE	any Integer number as String	The number of milliseconds after which the heartbeat message is repeatedly sent. The parameter is parsed with Integer.parseInt().
ECHO	"true" | "false"	If true, the MockDevice writes every byte read from the incoming stream to the outgoing stream, emulating an echo protocol

Example .properties-File style configuration (e.g., used in WsnDeviceUtilsGui):

UART_LATENCY = 100

BOOT_MESSAGE = Hello, World!
BOOT_MESSAGE_TYPE = ascii

HEARTBEAT_MESSAGE = Nummer Fünf braucht Input!
HEARTBEAT_MESSAGE_TYPE = ascii
HEARTBEAT_MESSAGE_RATE = 5000

ECHO = true
