25d81c98e4 Print not Aborting on Write() failure
Print::write(const uint8_t *buffer, size_t size) and Print::print(const
__FlashStringHelper *ifsh) would continue calling write(char) after a
failed write(char) this behavior would render returned count unuseable

4f87112c2e Add Serial_::availableForWrite().
This makes the CDC "Serial" object on the Leonardo and similar boards
support this recently introduced method as well. The CDC code in the sam
core is not changed.

9b7b23f045 Prevent losing bytes in HardwareSerial::end()
end() already waited for the buffer to be empty, but then there could
still be two bytes in the hardware registers that still need to be
transmitted (which were dropped or kept in the buffer, depending on the
exact timing).

This changes the wait loop to a call to the flush() function, which
already takes care of really waiting for all bytes to be transmitted,
meaning it is safe to turn off the transmitter.

b58f239400 Add Serial_::readBreak() to process SEND_BREAK requests
This allows detecting when the USB host sends a break request and what
the value of the request was. See the comments in USBAPI.h for details.

This just modifies the avr core, not the sam core.

96f7b966bc Expose serial settings from CDC virtual serial port
This allows a sketch to find out the settings chosen by the USB host
(computer) and act accordingly.

Other than reading the DTR flag and checking if the baudrate is 1200,
the regular CDC code doesn't actually use any of these settings.

By exposing these settings to the sketch, it can for example copy them
to the hardware UART, turning the Leonardo into a proper USB-to-serial
device. This can be useful to let the computer directly talk to whatever
device is connected to the hardware serial port (like an XBee module).

The Teensy core already supported these methods. This code was
independently developed, but the method names were chosen to match the
Teensy code, for compatibility (except that `dtr()` and `rtr()` return
`bool`, while the Teensy version return a `uint8_t`).

This change is applied to both the avr and sam cores, which have a very
similar CDC implementation.

Gcc 4.8 defines __cplusplus as 201103L, so we can check for that now. It
still also defines __GXX_EXPERIMENTAL_CXX0X__, but this could help on
other compilers, or if gcc ever decides to stop defining the
experimental macro.

04dba1e46f Fix off-by-one in String::substring
When checking the `left` argument, it previously allowed having
left == len. However, this means the substring starts one past the last
character in the string and should return the empty string. In practice,
this already worked correctly, because buffer[len] contains the trailing
nul, so it would (re)assign the empty string to `out`.

However, fixing this check makes it a bit more logical, and prevents a
fairly unlikely out-of-buffer write (to address 0x0) when calling
substring on an invalidated String:

	String bar = (char*)NULL;
	bar.substring(0, 0);

86015f441e Simplify String::remove(unsigned int)
Previously, this method calculated the length of the string from the
given index onwards. However, the other remove() method called already
contains code for this calculation, which is used when the count passed
in is too big. This means we can just pass in a very big count that is
guaranteed to point past the end of the string, shrinking the remove
method by a few bytes.

2068f88a21 Fix bounds check in String::remove()
Previously, if you passed in a very big index and/or count, the
`index + count` could overflow, making the count be used as-is instead
of being truncated (causing the string to be updated wrongly and
potentially writing to arbitrary memory locations).

We can rewrite the comparison to use `len - index` instead. Since we
know that index < len, we are sure this subtraction does not overflow,
regardless of what values of index and count we pass in.

As an added bonus, the `len - index` value already needed be calculated
inside the if, so this saves a few instructions in the generated code.

To illustrate this problem, consider this code:

String foo = "foo";
Serial.println(foo.length()); // Prints 3
foo.remove(1, 65535); // Should remove all but first character
Serial.println(foo.length()); // Prints 4 without this patch

Not shown in this is example is that some arbitrary memory is written
as well.

10a89a1d8d Support Atmega8 (and similar that define PE instead of UPE) again
These chips were previously supported, but since parity error checking
was added, this support has broken. Most chips define UPE0 (etc.) for
the parity error bit. Some chips don't have numbered UARTS so only
define UPE and even fewer define PE instead of UPE. This adds support
for those chips again.
