[PATCH] repost: improvements to rlgen-java

[David Waite]

The following patch changes the Java generation a bit:

- Array row/max are changed slightly to 12/8184 based on 80 column
display. This was just my own preference (some might prefer 10
columns, some would prefer the power-of-2-edness of 8 columns).  Toss
it if desired.

- Arrays are generated with an array constructor rather than a large
block of statement constructors. This reduced my packaged JAR size by
14k for a relatively simple JSON vocabulary with 68 states.
- Arrays are generated with whitespace padding in code for
readability.
- Array overflow (over the SAIIC limit) is done by creating multiple
functions with numbered prefixes, then generating a combine_<name>
function which builds a new array using new and arraycopy over all the
previous init_<name>_<number> functions.
