Many updates to format strings, largely as a result of changing
various "long" variables to uint32_t.
Fixed the diskimg debug macros for gcc, which requires an extra
"##" to remove the "," when there are no arguments. (Apparently
Visual Studio just strips this away for you.)
Stripped out a couple of dead variables spotted by gcc. Return
the actual error in a couple of HFS file functions.
This updates the project files for Visual Studio 2013, and removes
the old Visual Studio 6 (1998) project files. The update tool had
a number of complaints (see UpgradeLog.htm) that may need to be
addressed.
Also, replaced .cvsignore with .gitignore.
Visual Studio reports 1886 build errors, nearly all of them due to
the switch from MBCS to Unicode. The former is no longer
supported "out of the box", and its use is discouraged, so we're
going to bite the bullet and use wide characters in the UI.
