common: Rework the early cmdline argument parsing code to improve robustness 

Also move fast_return out of individual backends and into common code.

Gutenprint (eg via its gimp plugin) or the Windows print-to-file
output.
Extra debugging output can be enabled by setting the DYESUB_DEBUG
environment variable or passing the '-D' argument on the command line.
All global arguments:
If you have multiple models of the same printer family connected
simultaneously, the backend will choose the first one it finds. If you
wish to target a specific device, you may specify its serial number
in the 'DEVICE' environment variable or by passing the '-S serialnum'
argument on the command line. For example, these are equivalent:
-D Increment debug level [1]
-G Display GPL text
-f Enable fast return mode if possible [2]
-B name Use Backend 'name' [3]
-S serno Use SerialNum 'serno' [4]
-V extra_vid [5]
-P extra_pid [5]
-T extra_type [5]
-d numcopies Print 'numcopies' of the supplied job
DEVICE=N782 backend filename [ arguments ]
backend -S N782 filename [ arguments ]
[1] This argument can be repeated to increase the debug level.
Alternatively, the 'DYESUB_DEBUG' environment variable can be
used.
All backends support an additional operational mode, to test out
unknown models. To use this mode, specify the VID, PID and its
internal device type as arguments or environment variables:
[2] This terminates the backend as soon as the printer has
acknowledged the print job, without waiting for the print job
to complete. This can also be enabled by setting the
'FAST_RETURN' environment variable. This is the default behavior
when using this backend with CUPS. Not all backends support
fast return.
EXTRA_VID=04a9 EXTRA_PID=3ab1 EXTRA_TYPE=7 backend filename
backend -V 04a9 -P 3ab1 -T 7 filename
[3] Alternatively, you can use the 'BACKEND' environment variable.
The VID and PID are specified in hexidecimal, and the TYPE is
the P_XXX enumeration defined in backend_common.h. The '7' in this
example corresponds to most Canon SELPHY CP models, and is what you
would use if you were trying to get the backend to detect an
otherwise unrecognized SELPHY CP model.
[4] If you have multiple models of the same printer family connected
simultaneously, the backend will choose the first one it finds.
If you wish to target a specific device, you may specify its
serial number with this switch, or using the 'SERIAL' environment
variable. For example, these are equivalent:
If you are able to successfuly print using this technique, please let
us know so we can add the apppriate entry to the internal database.
SERIAL=N782 backend filename [ arguments ]
backend -S N782 filename [ arguments ]
[5] All backends support an additional operational mode, to test out
unknown models. To use this mode, specify the VID, PID and its
internal device type as arguments or environment variables:
EXTRA_VID=04a9 EXTRA_PID=3ab1 EXTRA_TYPE=7 backend filename
backend -V 04a9 -P 3ab1 -T 7 filename
