Michael Brown c117e6a481 [smbios] Allow reading an entire SMBIOS data structure as a setting 
The general syntax for SMBIOS settings:

  smbios/<instance>.<type>.<offset>.<length>

is currently extended such that a <length> of zero indicates that the
byte at <offset> contains a string index, and an <offset> of zero
indicates that the <length> contains a literal string index.

Since the byte at offset zero can never contain a string index, and a
literal string index can never have a zero value, the combination of
both <length> and <offset> being zero is currently invalid and will
always return "not found".

Extend the syntax such that the combination of both <length> and
<offset> being zero may be used to read the entire data structure.
