issue with Self keyword

[awestlake87]

when I generate this simple protobuf (excerpt taken from s2client-proto), the Self identifier triggers a compile error in rust.

protobuf file:

enum Alliance {
  Self = 1;
  Ally = 2;
  Neutral = 3;
  Enemy = 4;
}

generated code (using programmatic protoc-rust in build.rs)

...
#[derive(Clone,PartialEq,Eq,Debug,Hash)]
pub enum Alliance {
    Self = 1,
    Ally = 2,
    Neutral = 3,
    Enemy = 4,
}
...

Is Self supposed to be suffixed with _pb since it's a keyword?

Enum values are not escaped now. Going to look how hard is to fix it.

[stepancheg]

I've created a patch (currently testing) which adds value_ prefix to keywords, so Self becomes value_Self.

For a long time already field names which are rust keywords are prefixed with field_, so I followed this scheme.

Not sure about naming.

Published fix as 1.4.3.
