New subject: [PATCH 2/5] bhyve: generate NVRAM bhyve arguments

Currently, bhyve bootrom specification looks like this: bhyve ... -l bootrom,/path/to/firmware.fd In addition to that, it supports specifying the VARS files using: -l bootrom,/path/to/firmware.fd,/path/to/my_domain_VARS.fd Update virBhyveProcessBuildBhyveCmd() to include the VARS file if NVRAM is specified in the domain XML. Additionally, support copying this file from the specified template. To do that, introduce the bhyveProcessPrepareHost() and related helpers. They are currently not doing anything but NVRAM preparations, but should be useful for other host-side related tasks in the future.

New subject: [PATCH 3/5] bhyve: firmware: try to guess NVRAM settings

Extend bhyveFirmwareFillDomain() so that when we find the default edk2 firmware, also look for its matching template file, and use it as a nvramTemplate if found. Extend bhyvexml2argvtest to verify various NVRAM configurations.
