Have swtpm report PTM_CAP_SEND_COMMAND_HEADER flag for a TPM 2
indicating that it knows how to handle the TCG header prefix
for the data channel.

Implement support for TPM2. Some of the capabilities are not supported yet in
this patch.
Extend the man pages with description for --tpm2.
Missing: configure should probe for needed API calls in libtpms

We quetry the swtpm for TPM specification info that goes into the
certificate for the EK.
Update the test cases that now see more capabilties being returned
by the swtpm.

Implement a command for setting and querying the buffer size the
TPM implementation (libtpms) is using. The setting of the
buffersize allows to reduce the size of the buffer to a size
that the interface can support so that these two sizes match
and the TPM will not produce larger responses than what the
interface can support.
Extend swtpm_ioctl with an option to set the buffersize.
Adapt the existing tests to reflect the newly supported command.
Implement a new test for getting/setting of the buffer size.

As objected by QEMU upstream developers to use two different sockets for
starting/using of swtpm, This commit adds support for passing unix domain
socket over control channel.
The summary of the changes include:
- Defined new control command CMD_SET_DATAFD, using this clients can send data
socket.
- set mlp.fd and mlp.flags outside of the mainloop
- updated the testcases

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_ .

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.
