Reverting because this is causing Appveyor to be red. However
I hope we can reintroduce include_bytes! soon in a way that
works on windows. Fixes #1208.

This reverts commits 96c3641f
and 92e40470.

Changes since v0.1.12:
- First pass at running subprocesses (#1156)
- Improve flag parsing (#1200)
- Improve fetch() (#1194 #1188 #1102)
- Support shebang (#1197)

It was orphaned in 92e404.

Does not yet support streaming, only strings and TypedArrays for now.

To fix "cargo check" on travis, where they have silently upgraded us
from Ring 0.13.2 to 0.13.4, which has some errors.

Adds a general HttpHeader flatbuffer message for serializing requests
and responses.

And website upload tool.

Also Buffer.readFrom in fetch() to buffer response.

- Update to TypeScript 3.1.6 (#1177)
- Fixes Headers type not available. (#1175)
- Reader/Writer to use Uint8Array not ArrayBufferView (#1171)
- Fixes importing modules starting with 'http'. (#1167)
- build: Use target/ instead of out/ (#1153)
- Support repl multiline input (#1165)

Without HTTPS it might be possible for a MITM to inject arbitrary code into the "thumb.ts" response which Deno would then execute.

Because many Reader/Writer implementations (e.g. bufio) assume their
able to use subarray() with byte indexes and often ask for byte values,
it makes sense to simply restrict all implementations to Uint8Array.

Fixes #1104

This avoids the problem that when one of the caches is restored and the
other isn't, Rust doesn't get reinstalled, but it also isn't usable,
crashing the CI.

It was doing two independent things:
- print help and exit
- set log level

It's better to do those explicitly in main.rs

- 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.
