Use explicit cast when converting large integer types to smaller integer types when it is known that the most significant bytes are not required.
For pcidevice, check the ROM file size before casting to int. We'll allow expansion ROM sizes up to 4MB but usually they are 64K, sometimes 128K, rarely 256K.
for machinefactory, change the type to size_t so that it can correctly get the size of files that are larger than 4GB; it already checks the file size is 4MB before we need to cast to uint32_t.
For floppyimg, check the image size before casting to int. For raw images, only allow files up to 2MB. For DiskCopy42 images, it already checks the file size, so do the cast after that.
- Allow changing integer variables. Previously they could not be changed.
- Allow changing string variables. Previously they could only be changed if their length increased.
- printenv had a bug with strings longer than 32 characters.
- printenv now translates carriage return (used in nvramrc) as endl (which should perform carriage return and linefeed)
- For integers, setenv assumes decimal number input but if that fails it will try hex conversion. 0x prefix for hex numbers is optional unless the number only has digits 0 - 9.
- setenv converts linefeed to carriage return for string variables. nvramrc requires this for proper editing in Open Firmware.
- Added Open Firmware 2.4 nvram field names to OfNvramHdr comments.
