Added simple inverted String conversion.
When binding a primitive to an EditText, a common
pattern is to use '@{"" + value}'. This, however,
doesn't allow for a two-way data binding expressions.
To mitigate the need for conversion functions, a simple
inversion for this expression wsa implemented that
just converts value from a String when possible.
This CL also fixes a bug in which a method matching
the first parameter was always chosen, reguardless of
the second and further parameters.

Have two-way binding use localized variables to prevent NPE.
Bug 26962999
Two-way binding was using the inverted expressions directly
without localizing variables. That meant that if there was
a variable set to null during evaluation, it may get a
NullPointerException even though it checked for null
on the value previously. This CL localizes the variables
so that cannot happen.

Lambda In da house
This CL adds support for assigning callbacks to listeners using lambda expressions.
These expressions can receive either 0 or N arguments where N is equal to the
number of parameters in the callback function.
These expressions are evaluated when the callback is invoked. In other words, they
are independent from the rest of the ExprModel except the Identifier expressions.
Since these are limited to 1 full expression and they don't have any invalidation
flags; we use a verbose branching code generation mode where we calculate all possible
execution paths, eliminate trivial ones and generate the code. This allows callbacks
to be thread safe as well. See ExecutionPath class for details.
It is not efficient but since these are rere occasions, should be OK.
Callback expressions are still forced to be expressions that return value. To handle
`void` case, I've added `void` and `Void` as acceptable symbols. Also, if the callback
method returns void, the expression is free to return `void` or any other value.
¯\\_(ツ)_/¯
I've also moved kotlin to rc0. Although rc0 is unrelated to this task, it made more
sense to upgrade here because most changes it will ask for were already done in
this branch.

Two-way binding
Bug 1474349
Bug 22460238
This adds two-way data binding for those attributes
on Views that also have event listeners for them.
General use is also supported, but event listeners
are required to notify when those properties change.

Move toCode to Expr classes.
It turns out that toCode as part of Java is just
about as readable as in kotlin and it makes much
more sense than using instanceof (equivalent).

Remove guava from compiler
This CL removes all dependency from guava and replaces it w/ either plain
java or some utilities.
