There are two RootfsPropagation fields, one is Linux.RootfsPropagation,
the other one is LinuxRuntime.RootfsPropagation. They are duplicated,
one of them should be removed.
The RootfsPropagation is definitely a runtime specific configuration,
so we remove the one of Linux.RootfsPropagation.
And the description of it is moved from config-linux.md to
runtime-config-linux.md.

Based on our discussion in-person yesterday it seems necessary to
separate the concept of runtime configuration from application
configuration. There are a few motivators:
- To support runtime updates of things like cgroups, rlimits, etc we
should separate things that are inherently runtime specific from
things that are static to the application running in the container.
- To support the goal of being able to move a bundle between hosts we
should make it clear what parts of the spec are and are not portable
between hosts so that upon landing on a new host the non-portable
options may be rewritten or removed.
- In order to attach a cryptographic identity to a bundle we must not
include details in the bundle that are host specific.
'From' and 'To' are potentially ambiguous for a one-to-one map like
this, and there's already an established name convention in
SysProcIDMap [1]. This commit removes the mental overhead of two
separate naming schemes for the same information. I'd like to drop
IDMapping entirely in favor of SysProcIDMap, but SysProcIDMap doesn't
give the JSON hints we need for (de)serializing.

- link to official SemVer page
- link between config.md and config-linux.md and explain relationship
- fix typo (arch -> os)
- tweak formatting of some special characters
This moves some of the linux specific options like namespaces and
devices to the linux config document. It also removes processes as an
array and replaces it with a single process.
It adds the "platform" struct for OS and Arch and updates many of the
examples to match the changes. I also remove some of the redundant
windows examples on the portable spec document because they did not add
any extra value and many values were the same.

We had an in-person spec discussion, lets separate the spec into some
high-level sections to clarify future discussion.
Crosby agreed to let me merge to master :)
