What's changed and what's your intention?

This patch fixes an issue that I came across while working on other modules sit in common. Our macro module cannot compile by itself.

The macro module depends on both syn 1.0 and syn 2.0. I have no idea why it works but it turns out working when you compile the whole thing from root level.

This patch completely removed usage of syn 1.0 from macros, upgraded to syn::meta::parser for getting attributes. It also changes data type of those macro attribute value from string literal to ident, because it's actually used as ident.
