The RWLockWin::Create() function returns NULL on some Windows platforms because it cannot load kernel32.dll. This causes a crash.
RWLockWin tries to load kernel32.dll to check if the Slim Reader/Writer Lock APIs are present in kernel32.dll but on newer Windows platforms, kernel32.dll does not exist and the APIs are exported by kernelbase.dll instead.
The fix is quite simple: There is no need to try to load any DLL to check if the Slim Reader/Writer Lock APIs are present, because these APIs
are always present in all Windows versions since Windows Vista.
I am removing the code that attempts to load kernel32.dll. This prevents the crash on platforms that use kernelbase.dll.
If the WINUWP preprocessor symbol is defined, RWLockWin was already doing the right thing. But this issue is not limited to WINUWP and in
some scenarios, building for WINUWP is not the right solution because it causes other problems. So, my fix is essentially to use the WINUWP
code path for all Windows builds.
The only version of Windows which does not have the Slim Reader/Writer Lock APIs is Windows XP (and older ones, of course.)
However, since the current code does not fall back to an alternative implementation when the Slim Reader/Writer Lock APIs are missing,
WebRTC is already broken on such old versions of Windows.

Concatenating __FILE__ with __LINE__ prevents the compiler from

bloat. Chrome already omits from the file number from its Location

This new metric is currently unused, but will

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 no-op change that just removes the AudioAllocationSettings
helper class that was previously introduced since the field trials in it
were used in several places. Those other usages has now been removed
and AudioSendStream is now the only user. By moving the trials directly
to AudioSendStream we reduce the reader overhead when trying to follow
what a particular field trial does.
The "WebRTC-Audio-ForceNoTWCC" trial was removed as it is always set
together with "WebRTC-Audio-ABWENoTWCC".

wlan was previously classified as WiFi only on Android, while some

causes a WiFi interface to be assigned a higher network cost than
designed when we rely on the name matching to identify the network
type, which has further implication in the ICE candidate pair selection.

default rounding is desired. Typically this rounding is inlined.
e.g. as (<x> + <y>/2) / <y> making code more clumpsy (<y> might be long expression)

This change introduce small helpers to address both concerns.
