Avoid division by zero.

Before this patch, small images (i.e. 7x7 pixels or less) could trigger
SIGFPE because of a (integer) division by zero.

Strip alpha channel from PNG images with tRNS chunk
...
When PNG transformations are set up, tRNS chunk is converted to alpha channel
early in the process. Later the decision whether to strip alpha channel or not
is made upon checking (color_type & PNG_COLOR_MASK_ALPHA). Thus alpha channel
created by tRNS chunk conversion does not get stripped.

Use clock_gettime() instead of clock()
...
clock() provides approximation of processor time used, measured in "clocks".
Amount of clock per second varies between 100 (Minix, NetBSD, OpenBSD), 128
(DragonFly BSD, FreeBSD, older versions of MacOS X), 1000 (Windows) and 1000000
(Linux, newer versions of MacOS X, Solaris). The range of these numbers make
conversion to milliseconds (the unit of display in `qrtest`) problematic.
clock_gettime() with its nanosecond time base appears to be a better and more
portable alternative to clock().
