Static libraries don't guarantee that an exported symbol gets linked
into a shared library (and in order to support Chromium's component
build mode, WebRTC needs to be linked as a shared library).
Source sets always pass all the object files to the linker.
On the flip side, source_sets link more object files in release builds
and to avoid this, this CL introduces a the GN template "rtc_library" that
expands to static_library during release builds and to source_set during
component builds.

This is a reland of 890bc3069c
Zero bitrate caused division by zero in DCHECK for max bitrate.
Added unit tests to ensure that setting zero bitrate does not crash.

This is useful for internal calculations in bitrate control code as we
can skip conversion constants.
DataRate Example(TimeDelta time, DataSize size) {
double time_seconds = time.seconds<double>();
double size_bytes = size.bytes<double>();
double rate_bytes_per_sec = size_bytes/time_seconds;
return DataRate::bytes_per_sec(std::max(0.0,rate_bytes_per_sec));
}

By explicitly checking that the template argument is arithmetic, we
avoid exposing internal implementation details in the error message.

This is quite useful in many places where we need to restrict the range
of a DataRate. It makes it easier to read the intention than with:
value_ = std::max(some_lower_limit, std::min(value_, some_upper_limit));
The naming follows the naming for rtc::SafeClamp.

Negative infinity is useful in comparisons as it represents a value
guaranteed to be less than any other timestamp. This avoid using
Timestamp::ms(0) to represent such a value or having to use optional
for the special case of first time execution.
To avoid ambiguity, Timestamp::Infinity is renamed to PlusInfinity.

This adds new constexpr create function for DataSize, DataRate,
TimeDelta and Timestamp. The names are capitalized to mirror the
naming scheme of the previously constexpr methods (Zero and
Infinity create functions). They are also kept longer since they
are not expected to be used in complex expressions.

This makes the constructor and the unchecked create functions
constexpr on the unit classes Timestamp, TimeDelta, Datarate and
DataSize. This allows using the units in constexpr constants.
Unchecked access methods are made constexpr as well. Making them
usable in static asserts.
Constexpr create functions for checked construction is added in

The behavior of division-by-zero is undefined, so the DivisionByZeroFails test isn't correct. As we don't need any specific behavior on division-by-zero we leave the current code untouched.
Additionally, since the DivisionFailsOnLargeSize EXPECT_DEATH checks rely on DCHECKs, we only run those when DCHECKs are enabled.
