Summary:
This shows progress for the download of the JS bundle (different from the packager transform progress that we show already). This is useful especially when loading the JS bundle from a remote source or when developing on device (on simulator + localhost it pretty much just downloads instantly). This will be nice for the expo client since all bundles are loaded over the network and can take several seconds to load.
This depends on https://github.com/facebook/metro-bundler/pull/28 to work but won't crash or anything without it, it just won't show the progress percentage.
**Test plan**
Tested that bundle download progress is shown properly in RNTester on both localhost + simulator and on real device with network conditionner to simulate a slow loading bundle.
Tested that it doesn't cause issues if the packager doesn't send the Content-Length header.

Summary: When loading bundle from packager, "application/javascript" and "text/javascript" both refer to JS, so let's allow both for now.

Summary:
When using the packager behind something like an http tunnel it is possible something else than JS is returned, in that case throw an error instead of trying to parse it.
This is useful for Expo since the packager runs behind ngrok. This allows to intercept that error and show a more meaningful error message based on the ngrok response.
**Test plan**
Tested by changing the packager to return text/html content type and validate that the error shows up properly.
Also tested that it works when multipart response is disabled.

Summary:
Our iOS devs frequently turn off wifi and forget to turn it back on. This message should remind them that they need wifi to connect. Often they waste several minutes due to this problem.
I'm not sure if there's a test plan to apply here. Any suggestions?

Summary:
Since we are reading from a file, we should make sure this struct is packed, just in case we change it down the line and the compiler decides it might want to introduce padding, we're now protected against that.
There was also a discussion about the fact that people might use `ptr += sizeof(BundleHeader)` as an idiom in their code, which would currently be incorrect, if padding was introduced at the end of the file. Actually, it remains incorrect to do that now, because a RAM bundle header is a different size to a BC Bundle header. If people are properly testing their code, they should spot this pretty quickly, because it will always be an incorrect thing to do with a RAM bundle, so this isn't as bad as previously thought: where the code only succeeds when the compiler deigns to not pad the struct at the end.
This diff also cleans up how headers are initialised. `BundleHeader` has a constructor that explicitly zero-initialises it so we can rely on the default initializer to do the right thing now.

Summary:
Currently a build warning is thrown by `if (header.BCVersion != runtimeBCVersion) ...` because `runtimeBCVersion` is signed, apparently because `-1` is used to mean that the runtime has no support for bytecode bundles.
This PR splits out the error case of the runtime not supporting BC bundles from the case of a version mismatch.
Tested as much as I could by building and running `UIExplorer` - I haven't attempted to use real bytecode bundles.

Summary:
Strangely comparing a pointer with zero will only be a clang warning when compiling with `-Wpedantic`, so this incorrect comparison is silently allowed.
**Test plan**
Compiles with `-Wpedantic`.
