e5c0c426b7 Simplify parse_infix() 
- ASTNode::SQLBinaryExpr is now constructed in one location
- There's no duplicate calls to parse_in/parse_between
- The list of tokens that correspond to operators is not duplicated
  in parse_infix / to_sql_operator
- ...which made it easy to distinguish between errors that could be
  caused by invalid input and internal errors. I switched the latter
  to `panic!()`

c679c7a5b4 Remove Value::Uuid 
We don't have the code to parse UUID literals, so it's dead code, that
brings in the dependency on `uuid`.

I kept SQLType::Uuid, as it's not dead code, though it ought to be
dialect-specific.

50a2310173 Rename SQLStatement::SQLSelect to SQLQuery 
The name was confusing:
SQLStatement::SQLSelect(
  SQLQuery {
    body: SQLSetExpr::Select(SQLSelect)
  }
)

Fix the `large_enum_variant` clippy lint for `SQLStatement::SQLQuery`
`SQLStatement::SQLCreateView`, and `SQLSetExpr::Select`, while we're
changing the AST anyway

https://rust-lang.github.io/rust-clippy/master/#if_same_then_else

There was a bug in parsing `TIME` (not followed by {WITH | WITHOUT}
TIME ZONE) -- that parsed as SQLType::Timestamp instead of SQLType::Time

b12a19e197 Switch to the Rust 2018 edition 
This requires Rust 1.31 (from last year) to build, but is otherwise
compatible with the 2015-edition code.

d4de248c73 Support OVER clause for window/analytic functions 
Since this changes SQLFunction anyway, changed its `id` field to `name`,
as we don't seem to use "id" to mean "name" anywhere else.
