Add note about JSON tests maybe being wrong.

- Add note about the JSON test maybe not being correct yet.
- Add test to checks the generated names for double underscores to be sure they
  are what is expected.

More tests to shake out some cases in the json parsing

- String behaviors
- Testing only valid JSON is allowed

Adds better support for protos without packages and more warnings on possible improvements

Fixes #1844 

Add more JSON tests around underscores

Add a jenkins test status badge.

Fix up ignores and conformance generation

- Update ruby conformance generation for rename of generated files that seems
  to have happened.
- Update gitignores for the above and for the no-warnings-test.

Regenerate conformance files to include extra oneof fields.

This should fix the failures in the conformance tests - although
it highlights the problem that we need to do this when changing
the conformance.proto file...

Fixes extra whitespace on generated comments.

Objc more reset tests

Code already works, but make a bank of tests that call it out so things are
very clean in the future just to be safe.

Objc fix oneof zeros and more oneof zero conformance tests

Incase the different runtimes have different generation/implementations for
for the different primitive field types, cover a larger range of the proto
types in the oneof zero tests.

If a message is proto3, then the zero values still count as being set one the
field is in a oneof.

Add tests to confirm oneofs work as expected in both syntaxes.

* Add conformance test for zero fields in oneofs.
* Add failures to the "expected" files.

Never use strlen on utf8 runs so null characters work.

Fixes https://github.com/google/protobuf/issues/1933

Add a new test that forces strings into two different implementations from the
NSString class cluster to help confirm we're exercising both paths by which
CodedOutputStream will extract data from an NSString.

Move the old +load test (that was flawed because the behavior really depends on
the type of string from the NSString class cluster); into a unittest that
targets the specific case we're adding a behavior confirmation on.

As a bonus, improve the TextFormat generation of string characters < 0x20.

Convert mapping of proto comments to appledoc format so they show up in Xcode and cocoadocs.

Fixes https://github.com/google/protobuf/issues/1866

fixed cmake config files install path

Work for #1866 

Migrates all the public class docs over to appledoc format.  While Xcode is fine with blank lines in `///` comments, appledoc (used by cocoadocs) isn't and was leaving a bunch of info off the doc pages.

The generator still needs to be updated to do this also; that will be a follow up CL.
