0705b7f4e6 bhyve: Avoid using a packed struct for xhci port registers
I believe the __packed annotation is there only because
pci_xhci_portregs_read() is treating the register set as an array of
uint32_t.  clang warns about taking the address of portregs->portsc
because it is a packed member and thus might not have expected
alignment.

Fix the problem by simply selecting the field to read with a switch
statement.  This mimics pci_xhci_portregs_write().  While here, switch
to using some symbolic constants.

There is a small semantic change here in that pci_xhci_portregs_read()
would silently truncate unaligned offsets.  For consistency with
pci_xhci_portregs_write(), which does not do that, return all ones for
unaligned reads instead.

98568a005a vmm: Allocate vCPUs on first use of a vCPU.
Convert the vcpu[] array in struct vm to an array of pointers and
allocate vCPUs on first use.  This avoids always allocating VM_MAXCPU
vCPUs for each VM, but instead only allocates the vCPUs in use.  A new
per-VM sx lock is added to serialize attempts to allocate vCPUs on
first use.  However, a given vCPU is never freed while the VM is
active, so the pointer is read via an unlocked read first to avoid the
need for the lock in the common case once the vCPU has been created.

Some ioctls need to lock all vCPUs.  To prevent races with ioctls that
want to allocate a new vCPU, these ioctls also lock the sx lock that
protects vCPU creation.

c0f35dbf19 vmm: Use a cpuset_t for vCPUs waiting for STARTUP IPIs.
Retire the boot_state member of struct vlapic and instead use a cpuset
in the VM to track vCPUs waiting for STARTUP IPIs.  INIT IPIs add
vCPUs to this set, and STARTUP IPIs remove vCPUs from the set.
STARTUP IPIs are only reported to userland for vCPUs that were removed
from the set.

In particular, this permits a subsequent change to allocate vCPUs on
demand when the vCPU may not be allocated until after a STARTUP IPI is
reported to userland.

67b69e76e8 vmm: Use an sx lock to protect the memory map.
Previously bhyve obtained a "read lock" on the memory map for ioctls
needing to read the map by locking the last vCPU.  This is now
replaced by a new per-VM sx lock.  Modifying the map requires
exclusively locking the sx lock as well as locking all existing vCPUs.
Reading the map requires either locking one vCPU or the sx lock.

This permits safely modifying or querying the memory map while some
vCPUs do not exist which will be true in a future commit.
