The NOLINTBEGIN block only covers warnings on `long` types and other styling issues but not clang-tidies.

* Support optional, user-directed collection of performance counters
The patch allows an engineer wishing to drill into the root causes
of a regression, for example. Currently, only single threaded runs
are supported. The feature is a build-time opt in, and then a runtime
opt in.
The engineer may run the benchmark executable, passing a list of
performance counter names (using libpfm's naming scheme) at the
command line. The counter values will then be collected and reported
back as UserCounters.
This is different from #240 in that it is a benchmark user opt-in, and
the counter collection is transparent to the benchmark.
Currently, this is only supported on platforms where libpfm is
supported.

* 'Use' values param in Snapshot when BENCHMARK_OS_WINDOWS
This is to avoid unused parameter warning-as-error
* Added missing include for <vector> in perf_counters.cc
* Moved doc to docs
* Added license blurbs

* escape special chars in csv and json output.
- escape \b,\f,\n,\r,\t,\," from strings before dumping
them to json or csv.
- also faithfully reproduce the sign of nan in json.
this fixes github issue #745.
* functionalize.
* split string escape functions between csv and json
* Update src/csv_reporter.cc

* Add FIXME in multiple_ranges_test.cc
* Improve handling of large bounds in AddRange.
Due to breaking the loop too early, AddRange
would miss a final multplier of 'mult' that
was within the numeric range of T.
* Enable negative values for Range argument
Fixes #762.
* Try to fix build of benchmark_gtest
* Try some more to fix build
* Attempt to fix format macros
* Attempt to resolve format errors for mingw32
* Review feedback
Put unit tests in benchmark::internal namespace
Fix error reporting in multiple_ranges_test.cc

Fixes #714.

* Fix compilation on Android with GNU STL
GNU STL in Android NDK lacks string conversion functions from C++11, including std::stoul, std::stoi, and std::stod.
This patch reimplements these functions in benchmark:: namespace using C-style equivalents from C++03.
* Avoid use of log2 which doesn't exist in Android GNU STL
GNU STL in Android NDK lacks log2 function from C99/C++11.
This patch replaces their use in the code with double log(double) function.

* 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

* Rename StringXxx to StrXxx in string_util.h and its users
This makes the naming consistent within string_util and moves is the
Abseil convention.
* Style guide is 2 spaces before end of line "//" comments
* Rename StrPrintF/StringPrintF to StrFormat for absl compatibility.

When generating a human-readable number for user counters, we don't
generally expect 1k to be 1024. This is the default due to the more
general purpose string utility.
Fixes #437
