PEL: Keep size statistics of PEL repo
Keep a running total of several size statistics of the PEL repository.
The statistics are:
* Total size of all PELs
* Total size of BMC created PELs
* Total size of BMC created informational PELs
* Total size of BMC created non-informational PELs
* Total size of non-BMC created PELs
* Total size of non-BMC created informational PELs
* Total size of non-BMC created non-informational PELs
Here, size refers to the disk size the PEL uses, which is different than
the file size. The disk size is retrieved from the stat() function and
is the number of 512B blocks used.
The term 'informational' above doesn't strictly refer to the
informational severity value (0x0), but also includes other cases, such
as hidden recovered PELs.
