Tolerate unstarted builds in rebaseline server.

Currently server.py --rietveld-issue will crash if there are any
unstarted trybots on the latest patch. Instead of crashing, warn
that the bot hasn't started yet.

Factor text size device mapping in SkScalerContext.

All of our font back-ends use the text size in some way other than
simple concatentation with the current matrix. The code here finds
the full device matrix and then decomposes it to extract the text
size.

FreeType, GDI, and DirectWrite use the text size as the pre-hint scale.
CoreText will not scale color emoji above the requested text size,
and certain features like 'trak' are performed on the text size.

add convexity logic and tests for scalar max, Inf, and NaN

PathOps relies on isConvex() only returning true for trivially
convex paths. The old logic also returns true if the paths that
contain NaNs and Infinities. Return kUnknown_Convexity instead
in those cases and in cases where the convexity logic computes
intermediaries that overflow.
