* fix crash on "https://support.apple.com/kb/HT208050"
* add missing initializer (stupid oversight)
* fix bogus overflow test (another nasty bug waiting to bite)
We desperately need warnings or idioms against such stupid errors.
Using constructors for all locally defined structures seems advidsable,
- split color/css functions from util.c into color.c
- add util.h and color.h for declarations
- util.c no longer includes qe.h
- move get_clock_ms() and get_clock_usec() to unix.c
- remove unused QString functions
- bump VERSION to 5.3.4s
fixed bug in cfb32_fill_rectangle
use c99 syntax for new style struct initializers instead of gcc specific
simplified tolower unsigned char hacks
fixed various sparse warnings
utf8_encode now returns the number of characters copied
simplified code accordingly
made local functions static
fixed shadowing issues
