Update to racer v1.2.10.

[rillian]

Current upstream release.

[rillian]

Can at least update to the current published version of racer, per #50.

Or so I hope, I haven't been able to run the tests locally.

[rillian]

Nope, test failures on both travis and appveyor

Builds with rustc 1.12 beta fail because of #50.

The InvalidHmac stanza is printed on master, so it's just the http::find_definition* tests which are failing.

[rillian]

The http::find_definition test failure looks like an improvement. The definition location and type is the same, but the context string contains only the single line instead of two lines run together.

The http::find_definition_multiple_dirty_buffers test shows multiple lines run together in the returned context where before it didn't. So this issue isn't fixed, but at least it's no worse than before.

Those two can be made to pass by just updating the expected context string. I'm stuck on the third failure, in http::find_definition_in_std_library which returns a syntax error on the given code. I tried adding a semicolon to the end of the let statement to correct the actual syntax error, and a println! to correct the unused variable warning, but neither helped.

Thanks for working on this, Ralph! I don't see the failure you're referencing at the moment. Travis shows both completions and definition tests passing for std.

test http::find_definition_in_std_library ... ok
test http::list_path_completions_std_library ... ok

[rillian]

You're right. I think I was seeing the extra failure locally because I had RUST_SRC_PATH set correctly. With these updates the tests pass on stable rust.

tests fail on 1.12 beta because of #50, and on 1.13 nightly scripts/assert_cargo_lock_unchanged fails. Good enough to merge?

[jwilm]

Yep, looks like I should take care of #50 ASAP. Thanks for working on this; I really appreciate it!
