Searching for the last "boot_aggregate" record in the measurement list
could inadvertently match a filename containing the string
"boot_aggregate". Prevent this from happening.

display_pcrs() should include PCRS 8 - 9 as they are non-zeros on some
systems. boot_aggregate may span PCRs 0 - 9 so check()'s info message
should be fixed accordingly.

Use the "functions.sh" tty color scheme, which defines SKIP as CYAN.

SKIP: CYAN (36)
Should VERBOSE or informational messages be color coded?

For each kexec, an additional "boot_aggregate" will appear in the
measurement list, assuming the previous measurement list is carried
across kexec.
Verify that the last "boot_aggregate" record in the IMA measurement list
matches. The "boot_aggregate" is either the last field (e.g. "ima-ng")
or the second to last field (e.g. "ima-sig") in the measurement list
record.

Calculate the boot_aggregate for each TPM bank and verify that the
boot_aggregate in the IMA measurement list matches one of them.
A software TPM may be used to verify the boot_aggregate. If a
software TPM is not already running on the system, this test
starts one and initializes the TPM PCR banks by walking the sample
binary_bios_measurements event log, included in this directory, and
extending the TPM PCRs. The associated ascii_runtime_measurements
for verifying the calculated boot_aggregate is included in this
directory as well.
