Summary

When creating a new hdd image in qt, there were a few issues:

• If the image to be created was greater than a certain size, bit 32 and above would get lopped off resulting in the wrong size created.
• Once an image with > 16 heads was written to config, the image config would be changed and head count clamped to 16.
• If you type in an image file (as opposed to using the file picker) in the new HD image dialog, the resulting file would get placed in $CWD instead of usr_path. The image file would be created, but in the wrong location. As soon as the settings were confirmed the image file would then be created in usr_path resulting in two image files.

To fix:

• The image size logic was happening as a 32-bit unsigned int due to toUInt() grabbing the calculated number. Changed the qt type to unsigned long long via toULongLong(). Changed the size var to quint64.
• Updated config.c max settings to match win_settings.c.
• Added a section in qt_harddiskdialog.cpp to add usr_path to the filename if the path is relative

Note: config.c should be updated to use constants for max_spt, max_hpc, etc. for each bus. I figured it would be better to add those in a separate PR.

• I have discussed this with core contributors already
