(svn r25559) [1.3] -Backport from trunk:

- Fix: Possible reading of uninitialised memory due to undefined execution order (r25551)
- Fix: [Windows] Race condition between two drawing threads could crash OpenTTD [FS#5571] (r25550)
- Fix: ICU returns the width of the visual run as if the trailing space was added (in case a newline was added). This caused the width to be more than the requested width, but it would still be drawn correctly [FS#5626] (r25547)
- Fix: Two small memory leaks (r25546)
- Fix: [GS] The checks and validations for setting the extra text in the town window became too stringent [FS#5625] (r25544)
