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.

Make flag parser its own project. It is still in the tools folder,
but can now be used by other projects.
Some changes to behavior in order to work with SkFlags:
enable-missing-warning and disable-missing-warning have become
enableMissingWarning and noenableMissingWarning.
exclude-config is now excludeConfig
--config now can only be listed once, but all configs listed
after it will be included (same with excludeConfig and match).
In addition, writeJsonSummary has been changed to
writeJsonSummaryPath for consistency with other path flags.
Provide an option to SkFlags to provide a short name, and use
it for the flags which have short names.
--tileGridReplayScales now takes space separated arguments,
like other inputs.
