Revert of Establish MojoChildConnection from BrowserChildProcessHostImpl (Closed)
DescriptionRevert of Establish MojoChildConnection from BrowserChildProcessHostImpl (patchset #9 id:190001 of https://codereview.chromium.org/2221153003/ )
Reason for revert:
ContentBrowserTest.BrowserCrashCallStack/RendererCrashCallStack are failing on
"Linux Tests (dbg)(1)" and "Linux Tests (dbg)(1)(32)" since this CL. Reproduced
locally and bisected to "Establish MojoChildConnection from
BrowserChildProcessHostImpl", also verified that reverting it on master locally
fixes the problem.
When it fails, the tests stall for a long time before failing. Sample from bot:
ContentBrowserTest.RendererCrashCallStack (run #1):
[ RUN ] ContentBrowserTest.RendererCrashCallStack

Original issue's description:
> Establish MojoChildConnection from BrowserChildProcessHostImpl
>
> Rather than have individual BrowserChildProcessHostImpl users
> create their own connection, this moves all that junk into BCPHI
> and allows its users to configure it with a service name and
> instance ID.
>
> Also changes ChildProcessHost to support ChannelMojo connection
> via remote interfaces provided by its delegate, and uses this
> in conjunction with the BCPHI changes. Eliminates one more use
> of kMojoChannelToken.
