f0cf13c89b HID: Renamed fields in HIDDescriptorListNode and HID_Descriptor
In particular HIDDescriptorListNode.cb has been renamed to
HIDDescriptorListNode.descriptor because it contains decriptor data
and not callbacks.

Moreover the HID_Descriptor.descriptor field has been renamed
to HID_Descriptor.data so the structure has now two fields length
and data.

   typedef struct __attribute__((packed)) {
     uint16_t length;
     const void* data;
   } HID_Descriptor;

   class HIDDescriptorListNode {
   public:
     HIDDescriptorListNode *next = NULL;
     const HID_Descriptor *descriptor;
     HIDDescriptorListNode(const HID_Descriptor *d) : descriptor(d) { }
   };

This imply a change in the use of the node from:

  node->cb->lenght
  node->cd->descriptor

to

  node->descriptor->length
  node->descriptor->data

e1a0350062 allow HID submodules to create runtime descriptors
with this PR you can add

\#include Keyboard.h
\#include Mouse.h
\#include HID.h

in the top of the sketch and you will expose a Mouse+Keyboard

From the library pow, simply add

static HID_Descriptor cb = {
	.length = sizeof(_hidReportDescriptor),
	.descriptor = _hidReportDescriptor,
};
static HIDDescriptorListNode node(&cb);
HID.AppendDescriptor(&node);

in the class' constructor and you are done!

This fixes the Wire examples that uses I2C reserved address (from 0 to 7) substituting them with 8 that is the first one available and that can be used.

d6637e7f08 Updated EEPROM storage class
To avoid having a .cpp just for an extern variable definition, `static`
has been chosen over `extern`.

As the `EEPROMClass` class simply wraps functionality located elsewhere,
it is completely compiled away. Even though each translation unit which
includes the header will get a copy with internal linkage, there is no
associated overhead.

90ca3934f2 Prevent low pulse on TX initialization in SoftwareSerial
Previously, the TX pin would be set to output first and then written
high (assuming non-inverted logic). When the pin was previously
configured for input without pullup (which is normal reset state), this
results in driving the pin low for a short when initializing. This could
accidenttally be seen as a stop bit by the receiving side.

By first writing HIGH and then setting the mode to OUTPUT, the pin will
have its pullup enabled for a short while, which is harmless.

ead2881b1c Fix SoftwareSerial timings
Instead of using a lookup table with (wrong) timings, this calculates
the timings in SoftwareSerial::begin. This is probably a bit slower, but
since it typically happens once, this shouldn't be a problem.
Additionally, since the lookup tables can be removed, this is also a lot
smaller, as well as supporting arbitrary CPU speeds and baudrates,
instead of the limited set that was defined before.

Furthermore, this switches to use the _delay_loop_2 function from
avr-libc instead of a handcoded delay function. The avr-libc function
only takes two instructions, as opposed to four instructions for the old
one. The compiler also inlines the avr-libc function, which makes the
timings more reliable.

The calculated timings directly rely on the instructions generated by
the compiler, since a significant amount of time is spent processing
(compared to the delays, especially at higher speeds). This means that
if the code is changed, or a different compiler is used, the
calculations might need changing (though a few cycles more or less
shouldn't cause immediate breakage).

The timings in the code have been calculated from the assembly generated
by gcc 4.8.2 and gcc 4.3.2.

The RX baudrates supported by SoftwareSerial are still not unlimited. At
16Mhz, using gcc 4.8.2, everything up to 115200 works. At 8Mhz, it works
up to 57600. Using gcc 4.3.2, it also works up to 57600 at 16Mhz and up
to 38400 at 8Mhz. Note that at these highest speeds, communication
works, but is still quite sensitive to other interrupts (like the
millis() interrupts) when bytes are sent back-to-back, so there still
are corrupted bytes in RX.

TX works up to 115200 for all combinations of compiler and clock rates.

This fixes #2019

08fa593916 Disable the RX PCINT inside SoftwareSerial::recv
Before, the interrupt would remain enabled during reception, which would
re-set the PCINT flag because of the level changes inside the received
byte. Because interrupts are globally disabled, this would not
immediately trigger an interrupt, but the flag would be remembered to
trigger another PCINT interrupt immediately after the first one is
processed.

Typically this was not a problem, because the second interrupt would see
the stop bit, or an idle line, and decide that the interrupt triggered
for someone else. However, at high baud rates, this could cause the
next interrupt for the real start bit to be delayed so much that the
byte got corrupted.

By clearing the interrupt mask bit for just the RX pin (as opposed to
the PCINT mask bit for the entire port), any PCINT events on other bits
can still set the PCINT flag and be processed as normal. In this case,
it's likely that there will be corruption, but that's inevitable when
(other) interrupts happen during SoftwareSerial reception.

ce6b0f89e3 Optimize SoftwareSerial::setRxIntMsk()
This precalculates the mask register and value, making setRxIntMask
considerably less complicated. Right now, this is not a big deal, but
simplifying it allows using it inside the ISR next.

9d8f350ffe Mark SoftwareSerial::recv and handle_interrupt as always_inline
Since those functions are only called once now, it makes sense to inline
them. This saves a few bytes of program space, but also saves a few
cycles in the critical RX path.
