Nika Layzell b399ffc113 Bug 1522579 - Part 5: Reduce nsIContent{Parent,Child} to thin IIDs, r=mccr8
This devirutalizes a bunch of methods, and moves the entire implementation into
`Content{Parent,Child}` proper. The only purpose left for these types is as a
collection of interfaces and an IID for casting. They should likely be removed
entirely in a follow-up.

Ryan Hunt 590bdf0728 Bug 1500257 part 2 - Add PRemoteFrame stub implementation. r=qdot
This commit adds a PRemoteFrame actor which is managed by PBrowser. It will
be created in a child process nsFrameLoader when loading a remote subframe.

This actor will mostly just bounce messages from a nsFrameLoader in the child
process to the actor in the parent process which will redirect the messages
to the TabParent of the remote subframe.

The piece in the parent actor to create the proxied PBrowser actors is
deferred to the next commit.

This is needed because early in a content process's lifecycle, NeckoParent may
not have been created yet. This leads to issues when trying to redirect into a
fresh process which hasn't performed network loads yet. By sending the message
over PContent, we can be sure the APIs are available.

This actor can be used for communicating with individual frames, without
depending on walking the tree in the content process.

This is not yet complete. No tests have been written for it, the
WindowGlobalParent objects need to be exposed to chrome JS, and a form of JS
actors should be installed under them.

In addition, BrowsingContextChrome objects should be updated to allow access to
the current WindowGlobalParent in that context.

Jed Davis 231d5adb97 Bug 1446161 - Remove the earlier attempt at async launch. r=spohl,mccr8
The first attempt at async launch tried to hide the asynchrony inside
IPC, by making the process seem to be launched enough to construct new
channels and send it messages, and lazily blocking on the pid/handle.
Unfortunately, in practice we wind up needing the pid/handle immediately,
and this requirement is too deeply embedded in IPC for that to be viable.

(The alternative that will be used instead -- exposing process launch via
an explicitly asynchronous promise interface -- is made simpler by
Project Fission's upcoming rewrite of how the DOM requests new content
processes.)

At the moment this isn't actually async because we immediately require
the pid and block on launch anyway.  It also crashes the entire browser
on otherwise recoverable launch errors, because code that wants the pid
isn't set up to handle that operation failing.

This is based on the SharedStringMap that's currently used for shared memory

as read-only, and shares it with each content process. Look-ups in the
snapshotted map are done entirely using data in the shared memory region. It
doesn't require any additional per-process state data.

Kris Maglione 8316d5a0c0 Bug 1463587: Part 3 - Add bindings for SharedMap, and expose it via process message managers. r=erahm,baku,bz
This is the first basic implementation of a shared-memory key-value store for
JS message managers. It has one read-write endpoint in the parent process, and
separate read-only endpoints for each child-process message manager.

Changes to the parent endpoint are broadcast to the children as snapshots.
Each snapshot triggers a "change" event with a list of changed keys.

It currently has the following limitations:

- It only supports basic structured clone data. There's no support for blobs,
  input streams, message ports... Blob support will be added in a follow-up
  patch.

- Changes are currently only broadcast to child endpoints when flush() is
  explicitly called in the parent, or when new child processes are launched.
  In a follow-up, this will be changed to automatically flush after changes
  when the event loop is idle.

- All set operations clone their inputs synchronously, which means that
  there's no trivial way for callers to batch multiple changes to a single key
  without some additional effort. It might be useful to add a
  delayed-serialization option to the .set() call in a follow-up, for callers
  who are sure they know what they're doing.

Kris Maglione 03bf0b5bdd Bug 1463587: Part 2 - Add a shared-memory structured clone key-value store. r=erahm,bz
This class allows one read-write copy of a map in the parent process to share
data with multiple read-only copies in child processes. The maps only hold
onto data as structured clone blobs, and deserialize them each time a key is
read.

This commit only provides the bare-bones data structures. Follow-ups will add
bindings, change events, and automatic flushes.

Kris Maglione 47c200749a Bug 1463587: Part 3 - Add bindings for SharedMap, and expose it via process message managers. r=erahm,baku,bz
This is the first basic implementation of a shared-memory key-value store for
JS message managers. It has one read-write endpoint in the parent process, and
separate read-only endpoints for each child-process message manager.

Changes to the parent endpoint are broadcast to the children as snapshots.
Each snapshot triggers a "change" event with a list of changed keys.

It currently has the following limitations:

- It only supports basic structured clone data. There's no support for blobs,
  input streams, message ports... Blob support will be added in a follow-up
  patch.

- Changes are currently only broadcast to child endpoints when flush() is
  explicitly called in the parent, or when new child processes are launched.
  In a follow-up, this will be changed to automatically flush after changes
  when the event loop is idle.

- All set operations clone their inputs synchronously, which means that
  there's no trivial way for callers to batch multiple changes to a single key
  without some additional effort. It might be useful to add a
  delayed-serialization option to the .set() call in a follow-up, for callers
  who are sure they know what they're doing.

Kris Maglione 2bbae5374b Bug 1470365: Part 1 - Add a compact, read-only, shared-memory string map class. r=erahm
This class implements a shared memory key-value store that fits into a single
memory mapped segment. All of the runtime data for its instances are stored in
the shared memory region, which means that memory overhead for each instance
in each process is only a few bytes.

Importantly, the key and value strings returned by this class are also
pointers into the shared memory region, which means that once an instance is
created, its memory cannot be unmapped until process shutdown.

For the uses I intend to put it to, this is a reasonable constraint. If we
need to use it for shorter-lived maps in the future, we can add an option to
return non-literal dependent strings that will be copied if they need to be
kept alive long term.

Kris Maglione fd093e7cca Bug 1463587: Part 1 - Add helper class for creating snapshots of shared memory regions. r=jld,erahm
This class allows us to map a read-write shared memory region, and then safely
remap it read-only, so that it can be shared with sandboxed content processes.
