Bug 1450232 - in IPC, check that lengths fit in the available data before allocating data; r=mccr8 ...
There are three things we want to be true:
a) If the child sends a large value and the parent can't allocate enough space
for it we use an infallible allocation so the parent dies with an OOM.
b) If a fuzzer generates (huge-length, small-data) we don't try to allocate
huge-length bytes; knowing that the read will fail.
c) No fuzzer-specific branches in the core IPC serialization code.
Finally, this makes (huge-length, small-data) consistent with other cases where
the data is potentially truncated: ReadParam returns false.
