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

Add the missing PTM_CAP_GET_CONFIG to the returned flags.
Fix the order of the flags on the way.
Fix the test cases that test for the flags.

New option '--ctrl clientfd=<fd>' is added to the control socket parameters.
The passed 'fd' is used as control channel client-fd and treated as single
client mode.
