Tim Duesterhus e5ff14100a CLEANUP: Compare the return value of XXXcmp() functions with zero 
According to coding-style.txt it is recommended to use:

`strcmp(a, b) == 0` instead of `!strcmp(a, b)`

So let's do this.

The change was performed by running the following (very long) coccinelle patch
on src/:
