Details: http://sigrok.org/wiki/Fx2lafw
This new driver (+ firmware) currently supports the following devices:
- ARMFLY AX-Pro
- Braintechnology USB-LPS
- EE Electronics ESLA100
- EE Electronics ESLA201A

- Robomotic BugLogic 3
- Saleae Logic
- USBee AX

and support for analog signal acquisition (on devices which have these
capabilities) will be added later.

accidentally deleted upon 'make distclean'.
* ChronoVu LA8 input file format: Improve autodetection of the file format.
