pacsort, introduce define for escape_char error code
The signedness of char is implementation defined. On systems where char is unsigned, comparing a variable of type char with -1 is never true, due to integer promotion rules. To avoid this, introduce a define for invalid field separators where -1 is cast to char. This will ensure that the return value check works for both unsigned and signed char. Fixes one warning [-Wtype-limits] for comparissons with -1 when compiling with -funsigned-char.
