Gregory Szorc is now the Build Config module owner

[Ted Mielczarek]

Effective immediately Gregory Szorc (gps) is now the Build Config module
owner. Greg joins a storied list of module owners who touched the build
system too much and got stuck owning it until they could find someone
else to pawn it off on.

Greg has been leading the way technically in build system work for a
while now, so in my mind this is more of a formality than anything else.
You have undoubtedly already interacted with the great work he's been
doing: mach, the fantastic new front-end driver for the build system, or
moz.build, our Makefile replacement for build system data. I expect that
this will continue, so making him module owner was an easy decision for me.

I will continue to serve as a peer of the Build config module, but Greg
will now have final say on all questions regarding build system work.

Regards,

Thank you, Ted. Thank you for being an excellent mentor and thank you
for this opportunity. Or, at least I think I should be thanking you -
I'm not quite sure what agony will suddenly find its way to my plate now :)

I also view this as mostly a formality. I'm not planning any sudden
changes of direction aside from what's already in the works - mainly the
moz.build transition and building out mach as a more user-friendly
frontend. Ted, Mike, Kyle, and others continue to know more about the
build system than I likely ever will. Please continue asking them for
review requests instead of now sending them my way ;)
