constructor, and instead create an _internal_only getter
that gets the needed information. This is a workaround for
a deficiency in gcc-4.4 that does not properly support
templated friend classes.

- Move the ObjC tests into the list and exclude them on linux, this will change
  where in the order they start, since they are longer, it will have other
  things run in parallel instead of them ending up last and taking the longest.
- Switch to the Xcode 7.3 image.
- Drop the use of xctool and stream line things through the full_mac_build.sh
  script. This means we end up with only one build script instead of two.
- Tweaks to the mac build script:
  - Make iOS Xcode version support explicit
  - Support Debug/Release only building
  - Change the OS X min parallel count to 2 to better deal with VMs.
- Split the travis ios tests into the two Xcode Configurations as the logs are
  choking travis.

- Add generator constant for the default framework name.
- Add generator api for making the CPP symbol from the name.
- Add generator api to see if it is a bundled proto file.
- Output a CPP conditional and two imports for the core library headers.
- Add helper for generating the #import for file headers to deal with the
  framework imports.
- Add a reference from the unittests to a WKT to use that to inspect how
  imports generate.
- Update the podspec to define the CPP symbol and require pods 1.0 (or later).

Fixes https://github.com/google/protobuf/issues/1457

- Env solution doesn't seem to always work, use template pod files and copy
  them in place instead.
- Flush the pods cache before and after runs.
- Make pod install verbose to have the info incase something goes wrong.

Otherwise the projects have to be opened once to create user schemes for the
command line builds to work.

- Add the folder CocoaPods will add to the root folder.
- Move and expand the entries in the objectivec directory.

- Add an Xcode 6.3 created default iOS Project.
- Add an Xcode 6.3 created default OS X Project.
- Add Podfiles to for both that use Protobufs from within the tree.
- Add a script to run the tests (and cleanup) to help confirm the state of the
  Protobuf.podspec and sources.
