Mark Mentovai 0c41b15496 Convert AsciiDoc documentation to Markdown
Most of the world, including the Chromium universe, seems to be
standardizing on Markdown for documentation. Markdown provides the
benefit of automatic rendering on Gitiles (Gerrit), and on GitHub
mirrors as well. Crashpad should fit in with its surroundings.

There are two quirks that I was unable to resolve.

 - Markdown does not allow **emphasis** within a ```code fence```
   region. In blocks showing interactive examples, the AsciiDoc
   documentation used this to highlight what the user was expected to
   type.
 - Markdown does not have a “definition list” (<dl>). This would have
   been nice in man pages for the Options and Exit Status sections.
   In its place, I used unnumbered lists. This is a little ugly, but
   it’s not the end of the world.

The new Markdown-formatted documentation is largely identical to the
AsciiDoc that it replaces. Minor editorial revisions were made.
References to Mac OS X now mention macOS, and tool man pages describing
tools that that access task ports now mention System Integrity
Protection (SIP).

The AppEngine-based https://crashpad.chromium.org/ app in doc/appengine
is still necessary to serve Doxygen-generated documentation. This app is
updated to redirect existing generated-HTML URLs to Gitiles’ automatic
Markdown rendering.

Scripts in doc/support are updated to adapt to this change. All AsciiDoc
support files in doc/support have been removed.

This is the App Engine app that serves https://crashpad.chromium.org/.
To work on this app, obtain the App Engine SDK for Go from
https://cloud.google.com/appengine/docs/go/download. Unpacking it produces a
go_appengine directory. This may be added to your $PATH for convenience,
although it is not necessary.
The commands in this README are expected to be run from the directory containing
app.yaml.
The App Engine SDK for Go provides App Engine packages at the “appengine” import
path, but not the newer “google.golang.org/appengine” path. The Crashpad app
uses the newer paths. See
https://github.com/golang/appengine#2-update-import-paths and
https://code.google.com/p/googleappengine/issues/detail?id=11670. To make these
available, obtain a Go release from https://golang.org/dl/, and run:
$ GOROOT=…/go_appengine/goroot GOPATH=…/go_appengine/gopath go get -d
To test locally:
$ …/go_appengine/goapp serve
Look for the “Starting module "default" running at: http://localhost:8080” line,
which tells you the URL of the local running instance of the app.
To deploy:
$ version=$(git rev-parse --short=12 HEAD)
$ [[ -n "$(git status --porcelain)" ]] && version+=-dirty
$ goapp deploy -version "${version}"
Note that app.yaml does not name a “version” to encourage you to use a git hash
as the version, as above.
Activate a newly-deployed version by visiting the App Engine console at
https://appengine.google.com/deployment?&app_id=s~crashpad-home, selecting it,
and choosing “Make Default”. It is also possible to delete old versions from
this page when they are no longer needed.
