Bruce Rogers 64435eabdc Accepting request 730437 from Virtualization:Staging
Update to v4.1.0. Also includes other major packaging changes as follows:
There is a new package maintenance workflow - see README.PACKAGING for details.
The sibling packages qemu-linux-user and qemu-testsuite are now created with the Build Service's MultiBuild feature. This also necessitates combining the qemu-linux-user changelog content back into qemu's. Luckily the delta there is quite small. Note that the qemu spec file is now that much busier, but added section markers should help reduce the confusion. Also qemu is being enabled for RISCV host compatibility, so some changes are related to that as well.

Allow for guests with higher amounts of ram. The current thought
is that 2TB specified on qemu commandline would be an appropriate
limit. Note that this requires the next higher bit value since
the highest address is actually more than 2TB due to the pci
memory hole.
