Fix a potential use-after-free on quirc_resize failure.
...
Before this patch, in the event of `q->image` reallocation success but
`q->pixels` failure, `q->image` would point to a freed memory.
After this patch, once quirc_resize() returns, `q->image` consistently
point to a memory address that can be freed.
There is still an inconsistency left in the example codepath: `q->{h,w}`
would hold the "old" values, while `q->image` allocated size would be
based in the requested width/height; hence the comment update about the
state of the QR-code recognizer (it should only be passed to
quirc_destroy()).

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().
