replace sqlindent with new test exe which can parse, lex and indent
rename LobMultiplier and LobUnits to PrecMultiplier and PrecUnits
remove support for limit syntax
remove the unreserved keyword list since it isn't useful
tests for row value constructors
tests for table value constructors
tests for query specifications
tests for explicit table
work on tests for setops,order by,offset,fetch and sort specification

get rid of code_units since these are not in sql2011
implement next value for

support collate postfix operator
support escape and uescape as postfix operators
change the collate support in substring and trim which isn't a special

next to eachother with no intervening whitespaces
improve number literal parsing to fail if there are trailing letters
or digits which aren't part of the number and aren't separated with
whitespace
add some code to start analysing the quality of parse error messages
