Introduce wait_for_file function to wait for a file for a max. amount of
time and have that function poll for the file to appear.

Add support for UnixIO and TCP control channels. Both types of
transport require that packets are sent in big endian format
and therefore some code needs to be adjusted for that. The
ioctl interface is local and in that case no endianess conversion
is done.
Add a new test case that uses the extended swtpm_ioctl tool to
test the control channel.

Extend the swtpm_bios tool with an option to give up physical presence.
Have the TPM error codes reflected in the exit error of 128.
Add a test case for the tool.

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

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.

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.

Add a test case that ensures that swtpm-localca automatically
creates a signing key and issuer cert if none is available.

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.

Create uniqe names for the /dev/vtpm* so that tests can run in parallel.
Also separate the state directories of the TPMs into individual temporary
dirs.
