Add support for --connect option for the socket version of the TPM.
This parameter takes the type, port, file descriptor and disconnect
options. Only TCP connections are currently supported.
See updated man pages.

Implement a control channel for the 'chardev' swtpm that implements
a minimal set of control messages for now.

character device and sends responses through it.

Add support for the --tpmstate dir=<dir> command line parameter.
It will be used instead of the TPM_PATH, unless it is not set.
Adapt two test cases for the new parameter.

Add support for --pid file=<pidfile> command line parameter support.
The swtpm_cuse and swtpm now write their process IDs (pids) into
a file.

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.

Add an ioctl that lets an application retrieve which keys are in use by the
TPM, i.e., file encryption or migration key
Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com>
The migration key ensures that TPM state blobs, when retrieved using the
ioctl for getting state blobs, are always encrypted with this key.
When the state is later on loaded back into the TPM using the ioctl
to set the state blobs, the migration key is used to decrypt them.
