Add on bhyverun a new option '-B' that gives the capability to change the smbios table type1 using an ucl based configuration file.

[araujo]

Summary

The smbios table type1 contains overall system information such like:
Manufacturer, Product Name, Version, Serial Number, SKU Number, Family and etc.

Would be interesting to let users be able to modify these attributes to allow them to emulate some specific system vendors.
As an example of usage at iXsystems, we are using it to simulate our enterprise product and be able to execute QA tests using bhyve.

Example of bios.conf file:

manufacturer="MY COMPANY"
version="5.0"
product = "MY PRODUCT" 
serial="1234567890"
family="MY FAMILY"

Example bhyve parameter:

bhyve -B /z/bios.conf

I guess that this revision is going to change significantly based on what you told me in the comment on D2448 but it might be relevant to future changes ;)

The -B option is missing from the synopsis section.
