Use separate COND/counter in console printer handler.
Add FEATURE_S370_CHANNEL to .vcproj pre-processor defines:

NOTE: This is purely cosmetic. Hercules uses makefiles to build with and thus does not use Visual Studio's pre-processor defines. It only uses the values specifically defined in its makefile. This change is only so the Visual Studio 2008 editor doesn't "gray out" (disable) source code because it thinks it's inactive.
Rename CCKDDASD_EXT struct fields to eliminate confusion:

To more easily locate (grep) code pertaining to one feature from another that of another it helps for them to use different variable names.
DEVBLK Shared Device Server field renames:

To more easily locate (grep) code pertaining to one feature from another that of another it helps for them to use different variable names.
Fix for issue #27 "Little issue with I/O subsystem":
