This collection of patches adds support of printing PCI info in JSON
format.

1st patch adds skeleton for creating structured object which can be
printed in JSON or another structured format.
2nd patch adds output of general PCI info which prints with -m, -k,
-[v]+ options, but without capabilities.
3rd patch adds PCI-E capability.

For example, we can easily, using jq utility, check speed of a device:
lspci -Jvv | jq -r '.[][] | select(.Device == "GK107M [GeForce GT 750M]") | .capabilities.express | {s1:.LnkCap.Speed, s2:.LnkSta.Speed, w1
:.LnkCap.Width, w2:.LnkSta.Width }'

{
    "s1": "8GT/s",
    "s2": "5GT/s",
    "w1": "x16",
    "w2": "x4"
}
