Split the source tree into two new directories.

PSSRC files are now in 'gs/psi'.
GLSRC files are now in 'gs/base'.

This is to facilitate build modularization and merging in the ghostpdl
tree.

NOTE: msvc32.mak is now in psi, not src.

+ *      0 - max_radix-1 for valid digits,
+ *      ctype_name for other characters valid in names,
+ *      ctype_btoken for characters introducing binary tokens
+ *        (if the binary token feature is enabled),
+ *      ctype_space for whitespace characters,
+ *      ctype_exception for exceptions (see scommon.h), and
+ *      ctype_other for everything else.
+ * Exceptions are negative values; we bias the table origin accordingly.

+ * If any of the values below change, you must edit the table.
