* fix: add boringssl backport to support node upgrade
* fix: Update node_includes.h, add DCHECK macros
* fix: Update node Debug Options parser usage
* fix: Fix asar setup
* fix: using v8Util in isolated context
* fix: make "process" available in preload scripts
* fix: use proper options parser and remove setting of _breakFirstLine
_breakFirstLine was being set on the process, but that has changed in node 12 and so is no longer needed. Node will handle it properly when --inspect-brk is provided
* chore: update node dep sha
* fix: process.binding => _linkedBinding in sandboxed isolated preload
* fix: make original-fs work with streams
* build: override node module version
* fix: use _linkedBinding in content_script/init.js
* chore: update node ref in DEPS
* build: node_module_version should be 73
In the GN build, libchromiumcontent is no longer a distinct library, but
merely a container for a set of scripts and patches. Maintaining those
patches in a separate repository is tedious and error-prone, so merge
them into the main repo.
Once this is merged and GN is the default way to build Electron, the
libchromiumcontent repository can be archived.
