Properly handle embedded nul delimited string lists

For example:

reserved-names="res1\0res2\0res3";

Where \0 is an actual embedded NUL in the source instead of a string
escape. To achieve this, use the len given by the lexer instead of
strlen.

Without this patch dtc will mangle the output and possibly hang on
realloc.
