- Performance and stability improvements on all platforms.
- Add repl (#998)
- Add deno.Buffer (#1121)
- Support cargo check (#1128)
- Upgrade Rust crates and Flatbuffers. (#1145, #1127)
- Add helper to turn deno.Reader into async iterator (#1130)
- Add ability to load JSON as modules (#1065)
- Add deno.resources() (#1119)
- Add application/x-typescript mime type support (#1111)

Pro:
time ./out/debug/deno tests/error_001.ts  3.0s -> 0.4s

Con:
time ./tool/build.py snapshot              33s -> 1m52s
out/debug/gen/snapshot_deno.bin            39M -> 121M

- Running repl from js side.
- Add tests for repl behavior.
- Handle ctrl-C and ctrl-D.

Do not confuse this with Node's Buffer. This is a direct port of Go's
bytes.Buffer - it allows buffering of Reader and Writer objects.

Run with: cargo clippy

And some other minor clean-ups in the same file.

Currently, the Travis chart displays "time" as the y-label of the graph, when in fact the unit is in minutes. (makes this consistent with other y-labels being "seconds")

Plus some minor improvements and clean-ups:

* Resolve DENO_BUILD_PATH to an absolute path if necessary.
* Rename DENO_BUILD_PATH to GN_OUT_DIR in places where it is supposed to
  be set by the build system (and not a user configuration variable).
* Output Cargo `rerun-if-*-changed` instructions first, so even if the
  build itself fails, configuration changes will still trigger a re-run
  of build.rs.
* Remove TODOs that are impossible.
* Re-run build.rs when the flatbuffer definition file changes.

- Based on code from @qti3e and @piscisaureus in #724 and #1125
  respectively.
- TODO The DENO_BUILD_PATH env var must be supplied and must be an
  absolute path, this restriction should be removed in future work.

Use msg_generated.rs as mod instead of crate.
