* Ensure we don't need benchmark installed to pass c++ feature checks
Requires removal of some dependencies on benchmark.h from internal
low-level headers, which is a good thing.
Also added better logging to the feature check cmake module.
* Address MSVC C4722 warning in tests
Some test paths deliberately exit, and it appears that the appropriate declspec
does not stop the compiler generating the C4722 warning as one might expect.
Per https://github.com/google/benchmark/issues/826#issuecomment-851995549
this commit ignores the warning for the affected call site.

* format all documents according to contributor guidelines and specifications
use clang-format on/off to stop formatting when it makes excessively poor decisions
* format all tests as well, and mark blocks which change too much
* Change to using per-thread timers
* fix bad assertions
* fix copy paste error on windows
* Fix thread safety annotations
* Make null-log thread safe
* remove remaining globals
* use chrono for walltime since it is thread safe
* consolidate timer functions
* Add missing ctime include
* Rename to be consistent with Google style
* Format patch using clang-format
* cleanup -Wthread-safety configuration
* Don't trust _POSIX_FEATURE macros because OS X lies.
* Fix OS X thread timings
* attempt to fix mingw build
* Attempt to make mingw work again
* Revert old mingw workaround
* improve diagnostics
* Drastically improve OS X measurements
* Use average real time instead of max
This patch does two things:
1. It overhalls the static initialization in Walltime to be simplier. It uses
a static variable inside WallTime::Now() to initialize the timer.
2. Add a logging mechanism so that the -v flag actually has meaning and
reimplement the CHECK macros to allow extra messages to be streamed in.
