This was added in bug 1355661, has been kept Nightly-only since then,
and was only used briefly for omni.ja, and eventually we switched
compression off entirely on omni.ja. If we ever switch compression on
again on omni.ja, it would likely be with zstd, which is much faster
on the compression side.

Win32 errors ERROR_DEVICE_HARDWARE_ERROR, ERROR_DEVICE_NOT_CONNECTED, ERROR_DISK_FULL need a mapping.
NS_ERROR_FILE_DISK_FULL is duplicate to NS_ERROR_FILE_NO_DEVICE_SPACE
Drive by: RejectJSPromise lacked some NS_ERROR_* mappings

This backs out all work from bug 1627075 as well as all of its
descendents. There were a few conflicts when backing this out but
overall it was pretty clean, so I would say it's a fairly mild
level of risk. Historically Nathan Froyd has reviewed these patches,
but he is no longer at Mozilla, and no one else is particularly
familiar with the code, so I am passing this off to RyanVM who has
at least been familiar with the history of the bug.

Opening our Omnijars can be expensive, and it should be deferrable until after
startup is completed, provided we have a startup cache. In a previous patch in this
stack, we implemented caching of the zip central directory for omnijars, but we
still have to open the file in order to hand the object off to various omnijar
consumers. In a later patch, we will wrap nsZipArchive access in a class which
will allow us to transparently cache nsZipArchive results. These two get us
most of the way to not needing to read from the underlying omnijar files during
startup, but there are still nontrivial pieces, like nsZipFind for instance,
which we don't want to just duplicate inside of a wrapper class, so we would
like to sort out a way in which we can use an nsZipArchive class, but not
actually back it up with the real underlying file until we really need data
from it which we can't find in a cache.

We would like to be able to defer opening the omnijar files until after startup
if the StartupCache has already been populated. Opening the omnijar files takes
a nontrivial time, at least on Windows, and almost everything in the omnijar
should be fairly compressible, and thus makes sense to live in the StartupCache.
See the last patch in this series for a little more discussion on numbers, but
tl;dr: we saw a 12% improvement in time to about:home being finished on reference
hardware with these changes together with the changes from the descendant patches.

Please double check that I am using this correctly. I believe we are
seeing the crash in the linked bug because we are not handling hardware
faults when reading from the memory mapped file. This patch just wraps
all accesses in the MMAP_FAULT_HANDLER_ macros.

Temporarily just sidestep the issue in bug 1546498 (crash with latest SDK
on startup in Windows 7) by just continuing to use the old method in
Windows 7. We saw no wins in telemetry for Windows 7 anyway, so we should
investigate why that is, and why we see a mysterious crash in the fallback
code, in a followup bug.
