3f5e373ee4 replace off_t with size_t to match system pointer size 
I was having an issue with size of off_t on a multi-gigabit file.
This may have been related to long being a signed 32 bits on MSVC.
But I think there is good reason to use size_t here in general:

40890e46ab Remove mmap dependencies with QFile 
QFile implements cross platform file mapping and removes this dependency entirely.
Also simplifies the file size and error to string handling logic.
