Fix crash in tqimage for certain malformed ppm image files
The ppm format specifies that the maximum color value field must be less than 65536. The handler did not enforce this, leading to potentional overflow when the value was used in 16 bits context. Based on Qt5 patch for CVE-2018-19872. Signed-off-by: Slávek Banko <slavek.banko@axis.cz>
