Do not call SkBufferHead::validate in SkROBuffer's destructor, which
may be called in a separate thread from SkRWBuffer::append. validate()
reads SkBufferBlock::fUsed, and append() writes to it, resulting in
a data race.
Update some comments to be more clear about how it is safe to use
these classes across threads.
Test the readers in separate threads.
In addition, make sure it is safe to create a reader even when no
data has been appended. Add tests for this case.
Mark a parameter to SkBufferHead::validate() as const, reflecting
its use.

recent changes to text rendering.
Uses linear coverage falloff. Produces results that are perceptually more
similar to L32 (raster and gpu). Smoothstep + sRGB was too soft.
Plumb the gamma-correctness via DrawPathArgs, which also paves the way for
other path rendering implementations to easily make decisions about rendering
technique based on that flag.
Fix a few typos and formatting issues from my most recent change.

This adds SK_VERY_LEGACY_CREATE_TYPEFACE which, when defined, provides
only the old interface.
Ideally, everyone would switch directly to SkFontMgr and use one of the
newer calls, but there is currently no path for current users to get
there. This updates all the internals to use SkFontStyle, after
switching these over the higher level APIs can be switched.

This doesn't really change API, just modernizes it.

Motivation: This function is used throughout SkPDF.
Note that the compiler can usually inline the result of strlen() for literal strings.

Also added SkSurfaceProps to SkSpecialImage, so that Image -> Surface conversion can preserve the desired behavior during filtering.
Many small changes, including a bunch of comments about places where we may be losing information right now. My approach was to ensure that if anything fails, it will always fall back to "legacy" mode - gamma-correctness is opt-in, so I'll just have to feed things through as missing cases are exposed.

If a filter does not affect transparent black, there's no
reason to allow the crop rect to expand beyond the optimal
size determined by onFilterNodeBounds(). So don't enlarge
the bounds unless the filter affects transparent black.
In order to determine which filters affect transparent
black, I've pulled the inverse of the canComputeFastBounds()
logic into a non-recursive, affectsTransparentBlack()
virtual, and left canComputeFastBounds() as a non-virtual,
recursive function that calls it.

The following are currently unused in Android, Google3, Chromium, and Mozilla:
- SkEvent
- SkTime::GetMSecs
- SK_TIME_FACTOR (also unused in Skia)
- SkAutoTime
I left uses of SkMSec more-or-less intact for SkEvent, SkAnimator, and SkInterpolator. SkInterpolator is used in Chromium, so I did not want to change the API. The views/ and animator/ code is crufty, so it didn't seem worthwhile to refactor it. Instead, I added SkEvent::GetMSecsSinceStartup, which is likely to be adequate for use in SampleApp.
I also left SkMSec where it is used to measure a duration rather than a timestamp. With the exception of SkMovie, which is used in Android, all of the uses appear to measure the execution time of a piece of code, which I would hope does not exceed 2^31 milliseconds.
Added skiatest::Timer to support a common idiom in tests where we want to measure the wallclock time in integer milliseconds. (Not used in tests/PathOpsSkpClipTest.cpp because it redefines things in Test.h.)
Removed tabs in tests/StrokerTest.cpp.
