Initial assumption with Arduino 101 was that the "alternate setting
name of the DFU interface" would be simple enough to be used as the
grep pattern when attempting to find the board in DFU mode.
However, for boards such as the 96Boards Carbon, this name includes
grep meta-characters, so the DFUUTIL_ALT environment variable is
provided as a numeric value, instead of the previously expected name
string.
In order to avoid false positives, we now check whether DFUUTIL_ALT
is a numeric value, and the grep pattern is adjusted accordingly to
search for either "alt=" or "name=".
Also take into account that the name might contain spaces.

Add DFUUTIL_DFUSE_ADDR to the list of dfu-util environment variables,
which can be used to flash DfuSe devices (e.g. STM32 based MCUs).

Flashing the Arduino 101 board over DFU can be tricky: the
dfu-util command line is cumbersome, and the reset button
must be pressed at the right time.
This script brings the convenience of 'make flash' for the
Arduino 101 board and for other boards that support the DFU
protocol. It checks whether the board is in DFU mode, and
prompts the user to reset it when needed.
The dfu-util command line is constructed from the following
environment variables, to be exported from the Makefile:
- DFUUTIL: path to the dfu-util executable, default: dfu-util
- DFUUTIL_PID: vendor_ID:product_ID of the board in DFU mode
- DFUUTIL_ALT: alternate setting name of the DFU interface
- DFUUTIL_IMG: path to the binary image sent to the board
