Fix a typo in two command names so that they are similar to
the command name spelling used for the ioctl's.

Move src/swtpm/swtpm.h.in to include/swtpm.h.in to make it commonly
available. Adapt all other programs to use it and display version information
in the help screen.

The receiving of TPM state blob ends when the last byte has been copied
into a response to the user. No more request need to be sent afterwards.

Support the read/write interface and POSIX API calls for transfer of
TPM state blobs.
Extend the swtpm_ioctl program to support this as well. Use the
environment variable SWTPM_IOCTL_BUFFERSIZE to set the size of the
buffer to use and enable the read/write interface in this (test)
program.

Since POSIX reserves the *_t namespace of types, remove it from
all our typedefs. While doing that, adjust the typedefs to all have
the prefix ptm_ .

Add an ioctl that lets an application retrieve which keys are in use by the
TPM, i.e., file encryption or migration key

PPC64 seems to not work with 8k blob sizes, but 7k worked.
To be on the safe size, we set the size so that the requests
and responses are below a 4k page size.
Add new ioctls to get and set the 3 different types of state blobs
from and to the CUSE TPM. Add test cases for testing the new ioctl's
on a CUSE TPM that stores the state encrypted and on a CUSE TPM that
stores it non-encrypted.
