This is useful when debugging bindgen, using C-Reduce on an input to bindgen, or
for constructing portable test cases when filing issues against bindgen.

Feature 699 constified enum module
This is a work in progress for issue #699 that adds the `--constified-enum-module` option to bindgen.
@emilio, could you give me some guidance on fixing the uses of the enum variant types? In the example below, `foo` should be replaced with `foo::Type`. I'm not sure of the proper way to rename `Item`s after the structures have been defined. My initial thought was to redefine the `CodeGenerator` trait to take a mutable reference to `item`, but that will not work because of the borrow checker. Thoughts?
Todo:
- [x] put constified enum variants in a `mod`
- [x] ensure references to constified enum `foo` are changed to `foo::Type`
- [x] handle `typedef` enums
-----
Given the input header `tests/headers/constify-module-enums.h`:
~~~c
// bindgen-flags: --constified-enum-module foo
enum foo {
THIS,
SHOULD_BE,
A_CONSTANT,
};
struct bar {
enum foo this_should_work;
};
~~~
`$ cargo run -- tests/headers/constify-module-enums.h --constified-enum-module foo --no-layout-tests` will output:
~~~rust
/* automatically generated by rust-bindgen */
pub mod foo {
pub type Type = ::std::os::raw::c_uint;
pub const THIS: Type = 0;
pub const SHOULD_BE: Type = 1;
pub const A_CONSTANT: Type = 2;
}
#[repr(C)]
#[derive(Debug, Copy)]
pub struct bar {
pub this_should_work: foo,
}
impl Clone for bar {
fn clone(&self) -> Self { *self }
}
~~~

- changing the Builder::no_unstable_rust method to the Builder::unstable_rust method
- changing the --no-unstable-rust flag to a --unstable-rust flag in src/options.rs
- changing bindgen-flags header in the test headers to remove the --no-unstable-rust flag
Fixes #757

Implement `Default` trait
We need `Default` trait to handle so many auto generated fields when create new structure.

Added catch_unwind to catch panic at generator
Fixes #50
- Adds a `catch_unwind` to catch panic at binding generation.
- Prints out a more detailed message that points to the potential misuse of flags, when `generate()` fails.
- Added false-by-default `verbose` option flag to specify whether detailed message should be printed for the time being
- [x] Ran all test cases
- [x] Verified that correct error messages appear when bindings fail to generate
- [x] Verified use of verbose flag
- [x] Considered changes made by `cargo fmt`

It parses interfaces and protocol but ignores base classes, and their
methods which don’t have arguments, the method signature is currently
ignored. Also you can pass objc class instances to C functions.
Next steps are inheritance/base classes, method signatures, properties,
categories. Then check with system headers what is missing.

This is mostly a work around https://github.com/servo/rust-bindgen/issues/426,
until we implement the proper fix.

Similar to our ability to emit the clang AST, this adds an option to
emit our IR for debugging purposes.

- The root crate is the `bindgen` binary
- Rust-ify the test suite, no more subprocesses!
- Update Travis config to test both crates
