Identifiers starting with one or two underscores are reserved for system
headers and toolchain implementations and should not appear in user code.
Also on OS X, the ucode __TYPES_H_ guard clashes with the system types.h
header. Rename all ucode header guards to avoid such clashes.
Supersedes: #43

Introduce new operators `?.`, `?.[…]` and `?.(…)` to simplify looking up
deeply nested property chain in a secure manner.
The `?.` operator behaves like the `.` property access operator but yields
`null` if the left hand side is `null` or not an object.
Like `?.`, the `?.[…]` operator behaves like the `[…]` computed property
access but yields `null` if the left hand side is `null` or neither an
object or array.
Finally the `?.(…)` operator behaves like the function call operator `(…)`
but yields `null` if the left hand side is `null` or not a callable
function.
