Pull request smbios-2024-04-rc2

* In smbios command
  - write 'Not Specified' for missing strings
  - show correct table size for SMBIOS2.1 entry point
  - adjust formatting of handle numbers
  - add missing colon after UUID
* In generated SMBIOS table
  - avoid introducing 'Unknown' string for missing properties
  - provide RISC-V vendor ID in the type 4 structure
  - provide the correct chassis handle in structure type 2
* Rename Structure Table Maximum Size field in SMBIOS 3 entry point

In the SMBIOS 3 entry point the Structure Table Maximum Size field was
incorrectly named max_struct_size. A Maximum Structure Size field only
exists in the SMBIOS 2.1 entry point and has a different meaning.

Call the Structure Table Length field table_maximum_size.

The SMBIOS table size for SMBIOS2.1 entry points is in field 'Structure

For RISC-V CPUs the SMBIOS Processor ID field contains

Signed-off-by: Heinrich Schuchardt <heinrich.schuchardt@canonical.com>

The SMBIOS specification describes: "If a string field references no string,
a null (0) is placed in that string field."

Accordingly we should avoid writing a string "Unknown" to the SMBIOS table.

dmidecode displays 'Not Specified' if the string number is 0.

Commit 00a871d3 ("smbios: empty strings in smbios_add_string()")
correctly identified that strings may not have length 0 as two
consecutive NULs indentify the end of the string list. But the suggested
solution did not match the intent of the SMBIOS specification.

When no string is present in a table, next_ptr points to the same
location as eos. When calculating the string table length, we would only
reserve one \0. By spec a SMBIOS table has to end with two \0\0 when no
strings a present.
