OS-8766 load_sdc_sysinfo forks cut and sed per line, adding ~850ms to every zone boot
The loop forked a subshell, cut and sed for each line of sysinfo
output, about 71 processes per call. The function runs from the zone
brand statechange hook, so every zone boot paid for it.
Measured on a compute node with an Intel Xeon Gold 6240:
load_sdc_sysinfo 842 ms -> 33 ms
statechange hook 1012 ms -> 161 ms
vmadm start to guest ready 2631 ms -> 1721 ms
Output verified identical under both bash and ksh93: 69 variables,
byte for byte.
load_sdc_bootparams and sdc_bootparams_keys below have the same
pattern and are left alone here; they were not on the path measured.

vm.js, vmadm: migrate-listen startup mode for bhyve live migration
Adds a first-class way to boot a bhyve VM in its live-migration
destination mode, replacing the /tmp/migrate.listen sentinel file
sidechannel with a properly scoped zonecfg attribute.
Interface:
vmadm start <uuid> migrate-listen=true
This flows through VM.start(uuid, extra, {migrate_listen: true}, cb)
→ startVM → startZone, which (for the duration of this single
zoneadm boot call only) adds a transient `migrate_listen=true`
attribute to the zone's config via zonecfg. The brand boot program
(usr/src/lib/brand/bhyve/zone/boot.c, illumos-joyent companion
change) reads the attribute and appends `-o migrate.listen=true` to
the bhyve argv, causing bhyve to skip bootrom + vcpu_reset and block
on its in-zone control socket waiting for import-state from the GZ
migration agent.
