pe.c: parse SBAT variable and perform basic verification
Per Peter Jones suggestion, we will be flexible in what data we expect
while parsing the variable. Three fields are mandatory:
component_generation, component_name_size, component_name
However we also support adding comments and additional information to be
added after component name, with ',' as a separator. Those information
will be ignored and not used for verification purposes.
So:
grub,1
and
grub,1,wow,this,is,my,comment
will provide exactly same set of data for verification.
