63927 - enable Necko to run w/o write privs. "necko-readonly"

Status: RESOLVED WONTFIX

(Core :: Networking, enhancement)

Description

[timeless]

Spun off from tree:
bug 40109 [RFE] Ability to start two instances of mozilla.
bug 63925 [RFE] enable Necko to run as a separate app.
bug 63926 [RFE] necko application MultiUser and MultiSession considerations

Necko-readonly promises to write nothing to disk and carefully marks segments 
as discardable.  Any http traffic that does not say nocache is marked as safe 
for discard. necko-readonly tries as hard as possible to not lose nocache 
content, because it's assumed to be irreplacable.

As needed, this necko must be able to release cached content to free memory.
