* Import iterator_adapters from google3
* Remove -Wconversion which is annoyingly hard to satisfy
* Strip dependency on absl_container from iterator_adapters_test
* Format and lint iterator_adaptors
* More flexible copyright checking in Travis
* Move -fvisibility-inlines-hidden from common_flags to cxx_flags
This option isn't supported by C (and causes the build to fail under
at least rodete).
Manifested error was:
```
-- Looking for include file openssl/rand.h
-- Looking for include file openssl/rand.h - not found
CMake Error at core/src/firebase/firestore/util/CMakeLists.txt:94 (message):
No implementation for SecureRandom available.
-- Configuring incomplete, errors occurred!
```
which is completely misleading. :(
* Fix exception include for std::logic_error
Was causing compiler error on (at least) rodete.
(http://en.cppreference.com/w/cpp/error/logic_error suggests that
stdexcept is the correct header.)
* Remove 'const' from vector contents.
vectors cannot contain const objects as the contained objects are
required to be assignable and copy constructable. (Not *quite* strictly
true; since c++11, this requirement now depends on the operations
performed on the container. But my compiler objects at any rate.)

* Add brackets as suggested (required) by my compiler.
* Add missing include
For LLONG_MIN, etc.
* Enable gnu extension to c++11 for firestore/util *test*.
We disable them by default (in cmake/CompilerSetup.cmake) but our tests
requires hexidecimal floating point, which is not supported in c++11
(though is supported in C++17, gnu++11, and others).

* Fix printf format for uint64_t
http://en.cppreference.com/w/cpp/types/integerhttps://stackoverflow.com/questions/9225567/how-to-print-a-int64-t-type-in-c
* Allow 0 length printf template strings in tests.
* Get rid of a multi line comment.
The backslash is apparently interpreted by the compiler cause the next
line to be ignored too. In this case, the next line is (currently) a
comment, and would be ignored anyways. (But that doesn't stop the
compiler from yelling.)
* Run ./scripts/style.sh
