small character classes overhaul:

Browse Source 
• make fast character classes even faster by removing the C_SUBOP2 hack
  in favour of a separate seldom-used ksh_issubop2 macro (which also
  makes ctype() side-effect-safe) which is a slower class (no change there)
• optimise cases of ksh_isalphx followed by a ksh_isalnux loop
  (used parsing variable names)
• remove a misleading comment in initctypes() about \0 from pdksh
• rename C_ALPHA to C_ALPHX to make it more clear the underscore is included
• sprinkle a few ord() in there
• add new ksh_isalpha() which tests for [A-Za-z] (slow character class)
• there is no '_:\' drive on OS/2 (which inspired the whole changeset)
