Doug Thayer bad3183238 Bug 1594577 - Record hangs which precede forced shutdowns r=froydnj 
In short - if a user forcibly terminates the browser because it seems
to be permanently hung, we currently do not get a change to record the
hang. This is unfortunate, because these likely represent the most
egregious hangs in terms of user frustration. This patch seeks to
address that.

If a hang exceeds 8192ms (the current definition of a "permahang" in
existing BHR terms), then we decide to immediately persist it to disk,
in case we never get a chance to return to the main thread and
submit it. On the next start of the browser, we read the file from
disk on a background thread, and just submit it using the normal
mechanism.

Regarding the handling of the file itself, I tried to do the simplest
thing I could - as far as I can tell there is no standard simple
serialization mechanism available directly to C++ in Gecko, so I just
serialized it by hand. I didn't take any special care with endianness
or anything as I can't think of a situation in which we really care
at all about these files being transferable between architectures. I
directly used PR_Write / PR_Read instead of doing something fancy
like memory mapping the file, because I don't think performance is a
critical concern here and it offers a simple protection against
reading out of bounds.
