Remove reST documentation, attendant updates.

The documentation covers topics not specifically relevant to libmaple,
so it doesn't make sense for it to be part of the libmaple source
distribution.

Delete the docs/ tree, and prepare libmaple for use with the new
leaflabs-docs repo, which will contain the docs from now on.

* README: update to reflect this change

* support/doxygen/Doxyfile: This is the old docs/Doxyfile

* Makefile: Add a doxygen target

* wirish/comm/HardwareSerial.h: fix reference to docs/.  The comment
  informing maintainers that the HardwareSerial interface is
  documented by hand refers to the docs/ tree, which no longer exists.
  Update it to refer to the separate leaflabs-docs repository.

* support/scripts/copy-to-ide: No longer build the documentation

-delayMicroseconds()
-===================
-
-Pauses the program for the amount of time (in microseconds)
-specified as parameter. There are a thousand microseconds in a
-millisecond, and a million microseconds in a second.

-Library Documentation
----------------------
-
-.. doxygenfunction:: delayMicroseconds
-
-
-Example
--------
-
-The following example configures pin number 8 to work as an output
-pin, and sends a train of pulses with a period of roughly 100
-microseconds::
-
-    int outPin = 8;
-
-    void setup() {
-      pinMode(outPin, OUTPUT);      // sets the digital pin as output
-    }
-
-    void loop() {
-      digitalWrite(outPin, HIGH);   // sets the pin on
-      delayMicroseconds(50);        // pauses for 50 microseconds
-      digitalWrite(outPin, LOW);    // sets the pin off
-      delayMicroseconds(50);        // pauses for 50 microseconds
-    }
-
-
-Caveats and Known Issues
-------------------------
-
-The longest time ``delayMicroseconds()`` can delay is bounded by its
-argument type and the STM32 clock rate to be (2^32 - 1) / 12
-microseconds, or less than 6 minutes.  For longer pauses, use of
-:ref:`lang-delay` is possible.
-
-Arduino Compatibility
----------------------
-
-While we have made every effort we could to ensure that the timing of
-``delayMicroseconds()`` is as accurate as possible, we cannot
-guarantee it will behave as the Arduino implementation down to the
-microsecond, especially for smaller values of ``us``.
