virtiofs support for kexec-tools
This patch add virtiofs support for kexec-tools by introducing a new option
for /etc/kdump.conf:
virtiofs myfs
Where myfs is a variable tag name specified in qemu cmdline
"-device vhost-user-fs-pci,tag=myfs".
The patch covers the following cases:
1) Dumping VM's vmcore to a virtiofs shared directory;
2) When the VM's rootfs is a virtiofs shared directory and dumping the
VM's vmcore to its subdirectory, such as /var/crash;
3) The combination of case 1 & 2: The VM's rootfs is a virtiofs shared
directory and dumping the VM's vmcore to another virtiofs shared
directory.
Case 2 & 3 need dracut >= 057, otherwise VM cannot boot from virtiofs
shared rootfs. But it is not the issue of kexec-tools.

introduce the auto_reset_crashkernel option to kdump.conf
This option will determine whether to reset kernel crashkernel
to new default value or not when kexec-tools updates the default
crashkernel value and existing kernels using the old default kernel
crashkernel value. Default to yes.
