pathconf: Define a new name called _PC_CASE_INSENSITIVE
Some FreeBSD file systems (msdosfs and optionally ZFS)
handle case insensitive file name lookup.
NFS (v3 and 4) provide an attribute to indicate this
capability, but without this patch, the NFS server does
not know if the file system does support this.
This patch adds the pathconf name_PC_CASE_INSENSITIVE
that can be used by the NFS server or user programs to
check for this feature.

virtio: Fix polling in virtqueue_dequeue()
The access of vq->vq_ring.used->idx needs to be volatile-qualified,
otherwise the compiler may optimize virtqueue_poll() into an infinite
loop if there is no data available upon the first poll.
Prior to commit ad17789a8569 this wasn't a problem since an external
function call after each poll inhibited the optimization.

sh: Implement simple parameter expansion in PS1 and PS2
This change follows a localized approach within getprompt() and avoids
full parser reentry. While this means we don't support advanced
expansions like ${parameter#pattern}, it provides POSIX-compliant basic
parameter expansion without the complexity of making the parser
reentrant. This is sufficient for the vast majority of use cases.

vmm: Fix a deadlock between vm_smp_rendezvous() and vcpu_lock_all()
vm_smp_rendezvous() invokes a callback on all vCPUs, blocking the
initiator until all vCPUs have responded. vcpu_lock_all() blocks each
vCPU by waiting for it to go idle and setting the vCPU state to frozen.
These two operations can deadlock on each other, particularly when
booting a Windows guest, when vcpu_lock_all() blocks waiting for a
rendezvous initiator, and the initiator is blocked waiting for the vCPU
thread which called vcpu_lock_all() to invoke the rendezvous callback.
Implement vcpu_lock_all() in a way that avoids deadlocks with
vm_smp_rendezvous(). In particular, when traversing vCPUs, invoke the
rendezvous callback on the vCPU's behalf to help the initiator finish.
We can only safely do so when the vCPU is IDLE or we have already locked
it, otherwise we may be racing with the target vCPU thread. Thus:
- Use an exclusive lock to serialize vcpu_lock_all() callers, which lets
us lock vCPUs out of order without fear of deadlock with parallel
vcpu_lock_all() callers.
- If a rendezvous is pending, lock all idle vCPUs and invoke the

riscv/vmm: Remove a redundant maxcpu check in vm_alloc_vcpu()
aplic_max_cpu_count() just returns the VM's max vCPU count, and
vm_alloc_vcpu() already checks that. Just remove this check so that
it's easier to merge vm_alloc_vcpu() into MI code.
If the APLIC really does require us to lower the limit, we should
instead adjust vm->maxcpu in vm_create().
No functional change intended.
