Import C-Kermit 9.0.304 Dev.08 code (8-DEC-2013) with slight modifictions to remove some old Kermit95-related registration/demo version related stuff.
Update readme
hexdump was renamed to ckhexdump in C-Kermit 9. Update the OS/2+NT modules to call that instead.
Missed excluding some of the old registration/demo code when importing C-Kermit 9 changes. Remove it again.
sys_errlist[] is not available in Visual C++. Doesn't seem to be used by anything so we'll just exclude it.
Fix version numbers on OS/2 and Win32 platforms: ck_s_xver and ck_l_xver still need to be defined. They also need to be initialised on the same way as all other non-mac platforms.
