Dan McGee 499e09734b Streamline alpm_splitdep() comparisons ...

This reduces from 5 to 3 the number of searches needed on the string
looking for a comparison operator, since we can so a second quick
comparison looking for '=' if we find '<' or '>'. It also makes every
search doable with strchr() or memchr() rather than the slower strstr()
method.

In testing, only 10% of splitdep calls (~1600 / 16000) during an -Ss
database load found a version comparison operator, so optimizing the not
found path to be require less work makes sense.
