Stefan Berger 48773fe3ea swtpm_setup: Check for unreasonable number of PCR banks (CID 370783) 
This fix addresses Coverity issue CID 370783.

Check for an unreasonable number of PCR banks returned from command sent
to swtpm. Limit the number of PCR banks that can be returned to '20',
which is more than enough.

Previously we may not have sanitized the variable correctly but safeguards
were in place:

Even if the 16 bit variable count was the maximum possible (0xffff) we
should be able to allocate the all_pcr_banks array of string pointers.

Safeguards to not overstep the parsed array are in place in the loop
that's entered afterwards where the count variable serves as a limit
for the loop.

SWTPM - Software TPM Emulator
      David Safford safford@us.ibm.com
      Stefan Berger stefanb@us.ibm.com

The SWTPM package provides TPM emulators with different front-end interfaces
to libtpms. TPM emulators provide socket interfaces (TCP/IP and Unix) and
the Linux CUSE interface for the creation of multiple native /dev/vtpm* devices.

The SWTPM package also provides several tools for using the TPM emulator,
creating certificates for a TPM, and simulating the manufacturing of
a TPM by creating a TPM's EK and platform certificates etc. Please read 
the READMEs in the individual tool's directory under src/.

Please consult the Wiki for information about swtpm:
