Compare version strings as in sort –version-sort

Compare version strings

This function compares strings S1 and S2

By PREFIX in the same way as strcmp.

Then by VERSION most similarly to version compare of Debian's dpkg.
Leading zeros in version numbers are ignored.

If both PREFIX and VERSION are equal, strcmp function is used for
comparison. So this function can return 0 if and only if strings S1 and
S2 are identical.

It returns number >0 for S1 > S2, 0 for S1 == S2 and number <0 for S1 < S2.
