5d101b8a7b Allow passing __FlashStringHelper* in addition to char* everywhere 
Arduino supplies the F() macro that allows easily putting strings in
PROGMEM and marking them with a custom type. Essentially,
a __FlashStringHelper* is just the same char*, but cast to a different
type, which allows for example Serial.print() to automatically handle
both PROGMEM and normal strings.

By letting this library accept __FlashStringHelper* as well, you can
use easily use the F() macro and reduce the chance of mixing up normal
and PROGMEM pointers.

22b77ecb68 Add Adafruit_MQTT_Subscribe::datalen 
This stores the number of valid bytes in lastread. Having access to this
information allows transmitting binary data as well, containing embedded
nul bytes.

22c3533745 Fix type of Adafruit_MQTT_Subscribe::lastread 
The lastread array stores the data bytes of the most recently read
received packet. It was previously declared as an array of pointers to
uint8_t, instead of an array of uint8_t, which obviously was not the
intention. Because the examples explicitely cast to (char*) for printing
(because Print::println(uint8_t[]) is not defined) and a pointer is at
least as big as uint8_t and memcpy uses void*, this problem did not show
up before.

565d9afd36 Add parenthesis to fix compiler warning 
Gcc warns when using = where == seems logical, and adding parenthesis
tells gcc you really mean =.

b996b096b3 Fix Adafruit_MQTT:subscribe() 
This method contained a loop that checked for an existing subscription,
but it only printed a debug message if so. Now, it immediately returns
true if the subscription is already registered.

When this method succesfully adds a subscription, it was documented to
return true, but the actual code did not return anything in this case,
resulting in a compiler warning. In practice, on AVR, the value of the
first argument would be returned, which likely evaluates as true, so
it is likely it actually seemed to work fine.

6879df86f6 Add Adfruit_MQTT::connectErrorString() method 
This easily allows printing error messages without having to hard-code
return values in the sketch and makes the example sketches a bit more
concise.

73f5be4e5c Use const pointers for payload 
The payload data is never modified by the library, so using const is
possible without any further changes. Using const allows using a string
literal, or String::c_str() as the payload.
