This CL was generated by running

git ls-files | grep -P "(\.h|\.cc)$" | grep -v 'sdk/' | grep -v 'rtc_base/ssl_' | \

grep -v 'spl_inl_mips.h' | grep -v 'data_size_unittest.cc' | grep -v 'timestamp_unittest.cc' \
| xargs clang-format -i ; git cl format

Most of these changes are clang-format grouping and reordering includes
differently.

890f62b8fe Provide robust and efficient variance computation for online statistics. 
This CL implements Welford's algorithm for a
numerically stable computation of the variance.
This implementation is plugged in SamplesStatsCounter class (adapter pattern).

A 'NumericalStability' unit test has been added,
whose previous implementation of SamplesStatsCounter failed to pass.

Follow-up CLs will factorize more occurences of duplicated and misbehaved
computations.

e4ed6ea63b Introduce stats calculator. 
It accumulate sample values inside it and provide API to calc
min/max/avg and percentiles. Current implementation will do it
in O(nlogn) time and planned to be used in the test code after
all time sensitive operations and also assume not too big amount
of data inside.
