Bug #13560
smbios(1m) should sanitize strings
100%
Description
Looking at this intel NUC, we seem willing to print strings as they're presented to us. One my SKUs is a literal ^E. Given the general quality of smbios info, it'd be a good idea to sanity check and print potentially escaped versions of all strings.
SKU Number: SKU number: ^E
(fixing that capitalisation would be good too).

For the moment, I've done things such that smbios the command escapes strings. We probably need to go through and figure out a way to make this work for libsmbios so consumers don't have to all deal with this, but there are a bunch of complications around memory allocation and lifetimes as a result that I decided to at least clean up smbios(1M) for the moment. We may want to do the same for libsmbios, but I've repurposed this for the moment for smbios(1M).
To test this, I took smbios images from:
- An AMD Rome based system running illumos
- A Lenovo laptop running Linux
- Rich's smbios image that triggered this
For each of them, I compared the smbios output before and after and found the only differences were the string being escaped in Rich's case and the more consistent SKU number.

I also ran the utiltests to get the smbios test suite. There is one unrelated failure noted below which I root caused to be #13600 and have fixed separately. The smbios tests all passed:
