Fix read past end of array in sr_analog_si_prefix_friendly.
In the case where the input unit was not in the array, the for loop would
complete, but the following test would then read past the end of the array
since 'i' would already have been incremented to the array size.
Spotted because unitless data was getting SI prefixes with no unit, though
this would not have been deterministically reproducible.

scpi-pps: Don't block waiting for a value on capture stop.
The comment says "A requested value is certainly on the way", but the code no
longer works this way. The receive handler requests a value and blocks until
it is received. There is no value pending between receive handler calls, so
this code now only leads to a timeout.

The _WIN32 variant is available pretty much on all compilers, others

alternative, but for now we standardize on _WIN32.
