[ios blink] IOSurface remote mapping

Allow renderer process on iOS to access IOSurfaces by sharing the memory
segment backing the IOSurface and mapping it as shared memory, avoiding
the use of IOKit to access the IOSurface which is blocked by sandbox.
Even though we're not using IOSurfaceLock/Unlock to synchronize CPU
access, this is fine since we enforce exclusive write access to the
IOSurface on the CPU or GPU in Chromium. We still need to signal that
the IOSurface was updated on the CPU so we do a IOSurfaceLock+Unlock in
UpdateSharedImage.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure.

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.

If you found a bug, please file it at https://crbug.com/new.
