1454816 - Flatten base::SharedMemory into SharedMemoryBasic

Status: NEW

(Core :: IPC, enhancement, P3)

Description

[Jed Davis [:jld] (on leave until 08-31)]

base::SharedMemory and mozilla::ipc::SharedMemoryBasic are basically the same thing, with SharedMemoryBasic_chromium.cpp being a thin glue layer.

We could remove one of the (confusingly many) shared memory classes by: translating base::SharedMemory into Mozilla style, changing its two implementations into SharedMemoryBasic implementations, adjusting other base::SharedMemory clients to use SharedMemoryBasic instead, and removing base::SharedMemory.

(At some point we may also want to reconsider the name ipc/glue/, because at this point a lot of it really isn't glue for anything.)

One complication here is that we'll probably need POSIX and Mach shared memory to coexist on macOS, at least in the short term.
