This changes the way crash reports for child processes happening too early
during the child process' startup. Before bug 1547698 we wrote a partial
.extra file with those crashes that lacked the process type. The user would
not be notified of those crashes until she restarted Firefox and even when
submitted those crashes would be erroneously labeled as browser crashes.
After bug 1547698 we stopped writing .extra files entirely for those crashes
which left orphaned .dmp files among the pending crash reports.
This patch does three things to improve the situation:
* It writes a partial .extra file so that the crashes are detected at the next
startup. So the user is still not notified directly of these crashes but she
can report them later.
* It adds the process type to the .extra file so that the crash reporters are
labelled correctly.
* It fixes a leak in the `pidToMinidump` hash-map. Since the crashes were
not finalized the `ChildProcessData` strucutre associated with them would
never be fred.

Bug 1570440 - [Web content] Firefox Crashes on CNN.COM (Windows7)
This change addresses an issue where VRShMem can be in an invalid state when
there is no VR process available. In this case, the VRExternalShmem struct is
allocated on the heap rather than accessed via shared memory. When VRService
stops, it clears this pointer, but cannot re-access it when it restarts. Thus,
this results in a nullptr crash when a tab Enters, Exits, and Re-enters VR.
The fix is to distinguish between in-proc heap allocation vs cross-proc shared
memory so that VRService can decide to make the call to LeaveShMem in its Stop
function. This will keep the heap allocation alive across service restarts and
prevent the null crash.

This change creates the new export CreateVRWindow from vrhost.dll. This API
results in spawning a new Firefox window with the Firefox Reality 2D UI and
returns data needed for the host to interact with it. VRShMem is used to pass
data across process boundaries during this bootstrap process.
Additional tests are added to vrhost to be later converted to unittests.

This requires replacing inclusions of it with inclusions of more specific prefs
files.
The exception is that StaticPrefsAll.h, which is equivalent to StaticPrefs.h,
and is used in `Codegen.py` because doing something smarter is tricky and
suitable for a follow-up. As a result, any change to StaticPrefList.yaml will
still trigger recompilation of all the generated DOM bindings files, but that's
still a big improvement over trigger recompilation of every file that uses
static prefs.
Most of the changes in this commit are very boring. The only changes that are
not boring are modules/libpref/*, Codegen.py, and ServoBindings.toml.

Currently it's completely unclear at use sites that the getters for `once`
static prefs return the pref value from startup, rather than the current pref
value. (Bugs have been caused by this.) This commit improves things by changing
the getter name to make it clear that the pref value obtained is from startup.
This required changing things within libpref so it distinguishes between the
"base id" (`foo_bar`) and the "full id" (`foo_bar` or
`foo_bar_DoNotUseDirectly` or `foo_bar_AtStartup` or
`foo_bar_AtStartup_DoNotUseDirectly`; the name used depends on the `mirror` and
`do_not_use_directly` values in the YAML definition.) The "full id" is used in
most places, while the "base id" is used for the `GetPrefName_*` and
`GetPrefDefault_*` functions.
(This is a nice demonstration of the benefits of the YAML file, BTW. Making
this change with the old code would have involved adding an entry to every
single pref in StaticPrefList.h.)
The patch also rejigs the comment at the top of StaticPrefList.yaml, to clarify
some things.

This change brings the related ShMem code from VRManager and VRService into a
new class, VRShMem. This is to support future work where this ShMem will be used
for other efforts. Having this code in the same class will enable it to be more
easily shared in these efforts.
Until the new class replaces the code in VRManager and VRService, it can be
exercised and validated with two instances of vrtesthost, with the -testmgr and
-testsvc parameters.
