The newest version of GN replaces the 'cpu_arch' and 'os' variables with 'current_cpu', 'target_cpu', 'current_os', and 'target_os', and also replaces 'build_cpu' with 'host_cpu', and 'build_os' with 'host_os'.
The roll also picks up the change to add a new 'gn clean'
command, some absolute path handling fixes, a check_includes fix for action_foreach(), and some minor
internal fixes.
This patch also updates the build config files to accommodate the GN changes in a backwards-compatible manner, i.e., the configs now will set cpu_arch and os correctly in the right contexts. They will also allow the users to continue to set os= and cpu_arch= in an args file, so no user builds (or bots) will break.
Once all of the bots and all of the build files have been updated to refer to the new variables instead of the old ones, we can drop the backwards-compatible versions.

The problem was that the toolchain definitions had an is_clang block in them, but this is only evaluated in the context of the default toolchain (so false for and Android build). But then when we were re-evaluating the build config for the host compile, it was forcing clang to true which was causing the clang flags to be set.
This changes the way we default the is_clang value. Forcing it to true prevents it from being overridden manually. In some cases, like mac, this is pointless. In other cases like Linux, we may want to turn it on and off. Changing this definition allows us to toggle it on and off for different toolchains as we desire.
Ideally I think the way of defining toolchains would be different to make this a bit more flexible, I'll think about this. But this will work for now.

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 Clang in the pure GN build (not the hybrid GYP mode).
Clang gave some warnings about compiler flags which made me realize that we were giving linker flags to the compiler in some cases. So I enhanced our pkg-config wrapper to to add libraries to the cflags (missing else), return ldflags separately, and also strip out -pthread which was getting included over and over.

This makes make_global_settings closer to the GYP version. Previously it had relied on GYP concatenating two lists when running with goma, but it doesn't actually behave this way, resulting in unexpected output.

Refactors the toolchain definitions by adding an include file to help defining GCC toolchains. This eliminates most of the duplication on Linux and Android. Adds make_global_settings for most Linux and Mac builds that should match the GYP build (this will require some more passes to get every place to be an exact match).
Fixes Android build issues in WebKit. Fixes the definition of is_android.
Renames the Linux toolchains to use the GN name of the CPU architecture so one can refer to them without conditionals. Remove conditionals from BUILDCONFIG.gn
Adds the gyp_header variable to the help (it wasn't getting inserted into the list of available variables).
