microphones.

2cd62b46cd Fix USB Busy error for kbd hid. Made kbd USB report descriptor be 
COMPILER_WORD_ALIGNED as done in #118 for mouse. Added COMPILER_WORD_ALIGNED
to other UDC_DESC_STORAGE declarations that might have the same issue in
the future.

062fac1d43 atmel-samd: Use link time optimization to reduce code size of builds which 
share space with the file system.

"Express" builds with SPI flash crash the compiler for some reason so its
currently disabled for them.

e3f9ee839a Add frequency changing support to PWMOut. 
You can either set it once up front, or set variable_frequency on custruction to
indicate that the frequency must be able to change. This informs whether a timer
can be shared amongst pins.

This also adds persistent clock calibration on atmel-samd. Once the device has
synced its clock frequency over USB it will remember that config value until USB
is used again. This helps ensure the clock frequency is similar on and off USB.

Lastly, this also corrects time.sleep() when on USB by correcting the tick counter.

7e08347d5c atmel-samd: Support composite CDC and mass storage USB device. 
Be careful to not use the flash file system while using mass storage
because both pieces of code attempting to change the fs can corrupt it.

1fa4c20c27 atmel-samd: Add Micro Trace Buffer support to the debug build. 
The Micro Trace Buffer records the history of the pc and can be used
to debug hard faults even when the stack trace is useless.

8f26d181c3 Blinking the LED works. Clocks should be set up correctly. 
Everything works fine without USB being plugged in but faults (I think) when USB is plugged in. This is switched away from the USB code from the bootloader onto the USB code thats generated by Atmel Studio using the high level classes from ASF.
