Summary:
`declareOpts` prevents strong Flow typing, and promotes default values, that may be different from a function to another (my goal is to remove defaults from the whole codebase except perhaps the public API). This changeset replaces it by Flow types and fixes callsites to be explicit on values.
This is the last callsite of `declareOpts` so I'll remove it, in a separate diff.

Summary:
Two things in there:
* Using `base64` was kinda broken, as it can contain slashes, invalid in file names. It would still work however because it would just create a second level folder when doing `mkdirp`. Still I think it's better to fix that correctness.
* Include the UID in the hash, so that different users have different folders for sure, and that we reduce potiential permissions issues. `tmpdir()` already returns a folder that's user-specific on OS X, but this is not a guarantee on all platforms.

Summary: Oftentimes packager stalls for several seconds after requiring a bundle, because it's busy cleaning up old cache files. We shouldn't do that when, for example, we just restarted packager. This changeset stores the micro-timestamp of the last collection so that we don't waste time next time.

Summary: It seems we don't need that one much anymore, as we have a FS-based cache for files, and removing the last callsites doesn't really change perf, as we have to read these files eventually (plus some of these are read from `HasteMap`, that I believe is already dead code).

Summary:
Don't build js bundles for debug simulator build configurations
Motivation:
We have more than one debug build configuration that we run in the simulator, and none of them are exactly named 'Debug'. We want to establish the convention that any simulator build configuration containing the word 'Debug' will not build the react js bundles. We believe this is less intrusive to the developer.

Summary:
Note: if this changeset causes some breakage, consider disabling rather than reverting. To disable, the call to `_preprocessPotentialDependencies` in `ResolutionRequest` can be removed.
It's a bit of an experiment. I couldn't see any particular regression caused by this, but I could see net improvement of the global cache performance, as it unlock much, much stronger batching: indeed, instead of discovering dependencies progressively, we synchronously figure out the list of all potential modules of a bundle, and kick-off cache fetching and/or transformations. So when it comes to fetching from the global cache, it'll do less requests, and each requests will ask for considerably more keys at a time.
Potential problem caused by this changeset: if a module's dependencies completely changed, then the first time we try to build the bundle it'll start transforming modules that we probably don't care at all anymore, spending precious CPU time for nothing. I've been thinking about it and I cannot see such a case happening much often. Even if it happens, it should not cause any bug or corruption, it would just take additional time.
Other potential problem: that this new code doesn't handle some types of edge cases. It's quite hard to figure out what could possibly break in the `ResolutionRequest` code (and I think it would benefit from a larger refactor). We do have a good test coverage for `DependencyGraph` and it seems to work smoothly, so I'm relatively confident we're not breaking edge cases.

Summary:
There is a bug with IP detection on Macs that have (1) multiple ethernet interfaces, (2) are using the second or third interface as their primary connection and (3) have extra loopback IPs configured (for example when running OpenVPN, running some Docker configurations or other more exotic applications). In those cases, automatic IP detection will falsely detect the IP as something like `127.94.0.1`, which will make it impossible to run debug builds from a physical device.
The underlying network configurations looks something similar to this (irrelevant parts omitted):

Summary:
When running an app on a real iPhone in debug mode, I occasionally get issues when trying to load the js bundle and I suspect the issue is with xip.io (and it doesn't look like I'm the only one: https://github.com/facebook/react-native/issues/12786https://github.com/facebook/react-native/issues/9688#issuecomment-272591839). So I've added the ability to optionally disable the use of xip.io if an env variable `DISABLE_XIP` is set.
Add `export DISABLE_XIP=true` to the `Bundle React Native code and images` build phase. Run the app on a real iPhone and ensure that it can load the JS bundle from the host computers IP.
