Bump v9.0.0-nightly.20191129

* build: cache the out directory for exact deps hash matches

* chore: generate a target based depshash discriminator

* fix: hash on gn args

* build: share logic on the mac builds

* build: ensure that the mksnapshot binary is built before stripping before zipping

* build: attach the workspace on macOS

* build: optimize the macOS checkout path for testing

* build: fix mksnapshot zip generation

* build: make the mac src cache restore work

* build: v2 out cache

* build: macOS cache restore is just stupidly slow

* build: strip more binaries

* build: attach the out cache to the workspace for macOS builds

* build: allow linux boxes to restore darwin out caches

* build: cat the deps hash target file

* build: ensure that the deps target hash matches on the linux box

* build: do not use host arch in target key

* build: force undefined in the target hash file

* build: only restore out cache when it isn't in the workspace

* build: fix the macOS cache workspace trick

* build: do not double restore

* build: remove the big stuff from the out dir

* build: workaround layer issue

* build: try it back on macOS again but with smaller thingy

* build: macOS needs the out cache now

* build: clean up for omptimal macOS path

* build: use old docker image

* build: idek at this point

* build: we need a deps hash

* build: yeah we need a checkout too

* chore: use testing env on save cache job

* chore: well that should fix the cache key thing

* chore: handle cross-OS path mismatch for src cache restore

* build: use a /portal directory to transfer the src cache appropriately

* build: use the correct docker image

* build: super perms for /portal

* build: increment out cache number

* build: ensure target hash is correct for args + disable pre-compiled headers on macOS

* build: wipe the cross-arch libffmpeg before building Electron

 #### Resolving conflicts
 When updating an upstream dependency, patches may fail to apply cleanly. Often, the conflict can be resolved automatically by git with a 3-way merge. You can instruct `git-import-patches` to use the 3-way merge algorithm by passing the `-3` argument:
 
-```bash session
+```bash
 $ cd src/third_party/electron_node
 # If the patch application failed midway through, you can reset it with:
 $ git am --abort

+        The <code>dialog</code> module in Electron allows you to use native

+      </h3>
+
+      <p>
+        This is a main process module because this process is more efficient
+        with native utilities and it allows the call to happen without

+            relayed back to the renderer process.
