Previously "gn args" printed build arguments. That has now moved to "gn args <outdir> --list" along with a new --short mode that's a bit more convenient for some uses.
Now "gn args" runs your editor on the build arguments for the given output directory, and re-generates the build given those arguments. This is an easier way to manage changing build arguments for a build (previously you would have to re-type everything or edit build.ninja manually).
"gn gen" now always uses the existing arguments for the given output dir, unless "--args" is manually specified (giving the old behavior of just using those). This also allows a more convenient way for a user to recover from a borked build (sincetimes I ran into a state where something was missing that prevent ninja from even starting enough to rebuild the build).
I removed the "show" and "refresh" ninja phony rules since the new commands cover those cases.
This patch adds some additional tracing to build startup since I noticed it was missing when trying to figure out why the args command was so slow (I fixed the main reason, it was with new code I added).
Added proper escaping for printing string values and unit tests for these.
Two minor build file fixes.

This fixes a lot of minor mistakes (mostly missing/extra files and flags) for the Mac GN build.
I separated out some clang flags into a config for extra clang warnings. Several of the third party libraries needed to remove this.
Removes the use_nss flag and uses !use_openssl. This is a result of discussion with rsleevi.
Removes extra duplicate net build file from secondary tree.
ui/gesture_events seems to be getting compiled in GN with more strict warnings than in GYP. Rather than fix this, I fixed the warning in the gesture recognizer unit test. It was returning a const copy (the const is pointless when you're copying).
This also removes a bunch of old GYP integration stuff that was left in the GN build.

Updates all rebase_path calls to use the new parameter ordering.
Use the new getenv function and delete the Python script we had to get the home directory.
Takes advantage of the new ability to have the default value of declare_args blocks be dependent on other values. This simplifies some code.

This hooks up detection for the "-arch" flag on Mac to set the GYP "ARCH" xcode variable. GN then removes the -arch argument from the compiler args, since GYP will then re-add it based on the ARCH value. Previously, not doing this resulting in mutliple "-arch" arguments to the compiler since GYP would always insert its own.
Disables some warnings on Windows for the re2 target to match the GYP build. The third warning (4018) that the GYP build sets is disabled globally so there's no need to do it for this target.
Hooks up some iOS SDK stuff.
