SkTaskGroup is like SkThreadPool except the threads stay in
one global pool. Each SkTaskGroup itself is tiny (4 bytes)
and its wait() method applies only to tasks add()ed to that
instance, not the whole thread pool.
This means we don't need to bring up new thread pools when
tests themselves want to use multithreading (e.g. pathops,
quilt). We just create a new SkTaskGroup and wait for that
to complete. This should be more efficient, and allow us
to expand where we use threads to really latency sensitive
places. E.g. we can probably now use these in nanobench
for CPU .skp rendering.
Now that all threads are sharing the same pool, I think we
can remove most of the custom mechanism pathops tests use
to control threading. They'll just ride on the global pool
with all other tests now.
This (temporarily?) removes the GPU multithreading feature
from DM, which we don't use.
On my desktop, DM runs a little faster (57s -> 55s) in
Debug, and a lot faster in Release (36s -> 24s). The bots
show speedups of similar proportions, cutting more than a
minute off the N4/Release and Win7/Debug runtimes.

Share command flags between dm and unit tests.
Also, allow dm's core to be included by itself and iOSShell.
Command line flags that are the same (or nearly the same) in DM
and in skia_tests have been moved to common_flags. Authors,
please check to see that the shared common flag is correct for
the tool.
For iOS, the 'tool_main' entry point has a wrapper to allow multiple
tools to be statically linked in the iOSShell.
Since SkCommandLineFlags::Parse can only be called once, these calls
are disabled in the IOS build.
Since the iOS app directory is dynamically assigned a name, use '@' to
select it. (This is the same convention chosen by the Mobile Harness
iOS file system utilities.)
Move the heart of dm.gyp into dm.gypi so that it can be included by
itself and iOSShell.gyp.
Add tools/flags/SkCommonFlags.* to define and declare common
command line flags.
Add support for dm to iOSShell.

skia_ios.mm
Get the app's Documents directory and pass use it to set the resource path.
This is a quick hack which will be replaced by a new application that is
a tiny shim around a command line tool.
SkImageEncoder.h
SkForceLinking.cpp
SkImageDecoder_CG.cpp
Add support for FORCE_LINKING so iOS sees the PNG encoder and others.
SkFloatBits.cpp
SkPoint.cpp
Handle denormalized numbers that are floored by the iOS ARM processor.
SkImageDecoder_iOS.mm
Remove empty encoder factory.
SkTouchGesture.cpp
Return early on empty state on touch rather than aborting (crashing)
JpegTest.cpp
Hal via stackoverflow.com says partial jpegs can be gray as well.
skia_test.cpp
Remove crash handler call for now to avoid link failure.
OverwriteLine.h
Remove fancy line overwrite for iOS.
Resources.cpp
Add interface to set resource directory based on runtime query.

Similar in spirit to gflags' undefok, I'd like to be able to ignore
specific unknown flags. This lets me run the same command line on, say,
a branch that's got a new flag and on a clean branch tracking
origin/master. This is handy for performance comparison, etc.
It's not essential, and if you hate this I can find another way.
As an example, I want to compare the runtime of SKP recording with my new code. I've added a flag --skr to bench_record to help this. So I want to compare
origin/master: out/Release/bench_record
my patch: out/Release/bench_record --skr
This lets me run both as out/Release/bench_record --undefok skr --skr, which is handy for scripts and things.

In SkCommandLineFlags, if the client sets a default value
of multiple arguments (e.g. "arg0 arg1 ..."), set
the actual defaults to all of those arguments separately
(i.e. an array with [0] == "arg0", [1] == "arg1", ...),
rather than as one string (i.e. [0] == "arg0 arg1 ...").
Remove the hack that worked around this bug.
Also move the increasingly complicated implementation of
SkFlagInfo::CreateStringFlag into the cpp file.

Two dashes are used for flags with multiple characters, and one
dash is used for flags with single characters.
In GM, changed '-wp' to '-p' (the command to choose a directory
for writing SKPs) to fit with the convention.
In render_pictures and bench_pictures, changed the flag for
read and write path to have full names (which are consistent)
and use the old single character names as their shortcuts.
SkCommandLineFlags: Updated the documentation, and only allow
-h or --help for help (again, to match the convention).
Also enforce the single character limit for the short name, and
require the full name to be at least two characters.
Provide full names for skhello.
