* Allow for custom domains in the FDL iOS SDK

Allow for custo domains to be whitelisted by the info.plist file.

* Fix style. Run ./scripts/style.sh

* style

* Update versions for Release 5.11.0

* Update Firestore Generated Protos (#1972)

* Remove cruft from project file (#1975)

* Lock reads and writes to session map

* Changed FDL to use compatible __typeof__() operator. (#1982)

typeof() is not supported in some C language dialects which causes
issues when integrating FDL in projects that do use non-GNU compiler modes.

For example, this causes problems when building in some versions of Unity
firebase/quickstart-unity#228

* Bump DynamicLinks patch version

* Add FDL to release manifest

* Bump GoogleUtilities patch version to deliver fix for #1964 (#1987)

* Wrap diagnostics notification in collection flag check. (#1979)

* Wrap diagnostics notification in collection flag check.

Some of the diagnostics notifications were missed and not covered by
the data collection flag.

* Remove redundant notification call, move Core diagnostics API call.

* Removed configure with no options test.

* Queue Storage Tasks on separate queue (#1981)

* Increase timeout for testDispatchAfterDelay (#1988)

* Update Storage Changelog (#1989)

* Add missing FirebaseStorage release note (#1990)

* Allow semicolon in file name (#1991)

*  Remove unnecessary notification flag (#1993)

* Remove unnecessary notification flag.

This was added when the Google pod could configure Firebase but the
Google pod is deprecated and can only work with Firebase 3.X. These
flags and conditional checks can be safely removed.

* Resolve issues from commit split.

* Style fixes.

* Reduce singleton usage in FIRApp tests. (#1995)

* Reduce singleton usage in FIRApp tests.

There have been some issues while creating new tests of conflicts with
mocks of classes and instances, this should alleviate some of those
conflicts in the future.

* Remove bad style changes.

* Use default app name flag instead of local variable.

* Comply with c99 standard (#1992)

* Trigger travis for Firestore podspec changes

* Use C99-compatible __typeof__ instead of typeof (#1985)

`typeof` is only defined if you compile with GNU extensions, while
`__typeof__` is always available.

This is the Firestore equivalent of #1982.

Note that Firestore won't yet build in this mode because among other
things the Objective-C gRPC still uses `typeof`. Once we eliminate that
dependency this might become possible.

* Adding AppCode Diff (#1996)

* Remove warning (#1999)

* Add InAppMessaging to Carthage template (#2006)

* Restore SafariServices framework (#2002)

* SafariServices not available on tvOS and not used on osx

* Force Firestore to conform to C99 and C++11. (#2001)

Note that c++0x is how Xcode spells c++11.

Also fix an issue where we were accidentally using a C++14 feature.

* Changing the internal testing repo (#2003)

* Clean up test. The issue has already been fixed and we are now running integration test with actual server instead of hexa. (#2007)

* gRPC: replace Objective-C implementation with the new C++ implementation (#1968)

* add support for SSL disabled to `GrpcConnection` (unfortunately, there
  currently is no way to verify this change actually works);
* make gRPC calls using the C++ implementation:
* make `FSTRemoteStore` create C++ streams instead of their Objective-C
  counterparts;
* port firebase/firebase-js-sdk#1041: streams
  are now never recreated, only restarted;
* make `FSTDatastore` delegate server calls to the C++ implementation;
* port `MockWatchStream` and `MockWriteStream` to C++ (`FSTMockDatastore` is
  still in place, because `Datastore` is not fully ported yet);
* no longer generate Objective-C gRPC service definitions from protos;
* remove all references to Objective-C gRPC client;
* check in gRPC root certificates file and load it at runtime (the check-in part
  is temporary until gRPC-C++.podspec provides the certificate). This makes SSL
  work.

* Add component system documentation.

* Fixed markdown layout issue.

* Remove trailing whitespaces.

* Add table of contents.

* Remove extra parentheses from TOC.

* Renamed SDKs to frameworks and products for accuracy.

* Updated the Carthage installation instructions (#2012)

* Add Rome instructions (#2014)

* Attempt to fix frequent Auth Unit Test flake on OSX (#2017)

* Increase timeouts in attempt to eliminate travis flakes (#2016)

* Don't rely on test always being in foreground (#2021)

* Fix log overflow in continuous fuzz testing (#2020)

Prevent generating too many "Unrecognized selector" console messages that eventually make Travis kill the job due to log exceeding limits.

* Assign the default app before posting notifications. (#2024)

Although SDKs being configured should access the app through the
dictionary being passed in (and soon the `FIRCoreConfigurable`
protocol), the default app should be assigned before notifying SDKs
that Core is ready.

* Update CHANGELOG for Firestore v0.14.0 (#2025)

* M37 Core release notes (#2027)

* Add changelog to GoogleUtilities

* Fix static analysis warning in Core. (#2034)

Explicitly check for `nil` instead of using the `!` operator on the pointer.

* Update CHANGELOG.md for #2034 (#2035)

* Revert "gRPC: replace Objective-C implementation with the new C++ implementation (#1968)" (#2030)

This reverts commit a514bd9.

* Partially revert "Update CHANGELOG for Firestore v0.14.0 (#2025)" (#2031)

This removes the changelog entry that describes our migration to
gRPC-C++.

* Move #2034 into 5.12.0 (#2036)

* Fix tablet layout for in-app messaging (#2032)

* Rename fine-tuning methods to reflect size class rather than orientation

* Modify existing constraints to de-portrait tablet layout, need a card width for tablet now

* Further constraint tinkering, add identifiers for better auto layout debugging

* More constraints for "landscape" appearance in tablet. Looks good for every case except Thin Image, which blows up the height of the message card

* Fix fine tune layout methods to correctly fine tune for compact height and width

* Update layout constraint identifiers to match titles in document outline for easier debugging
