Allow running swtpm_setup directly as tss user using the following
command lines as an example for how to do it:
mkdir /tmp/test-tss
chown tss:tss /tmp/test-tss
chmod 770 /tmp/test-tss
su -c "swtpm_setup --tpm-state /tmp/test-tss" -s /bin/sh tss
This change prevents us from requiring invocation under the root
user.

Replace the show_help variable with change_user varaible with
opposite logic. The name of the variable is better for upcoming
changes.

If the return code from the command processing function is 0,
get the error code from the command response and return that one
instead. The problem was that clients though resetting the
establishment bit worked in locality 0 for example, while it did
not.

Return the number of bytes received in case ctrlcmd does not
use an ioctl because in this case we need to know how many bytes
we received in the response.
The receiving of the state blob also needs to take into account
how many bytes were received in the initial response so we write
the proper amount of bytes from that response into the file.

While parsing the options we modified the argv[] values and
the commas disappeared, which showed when checking for the
swtpm processes using 'ps'. So, work on a copy of the options
parameter.

Implement allow-set-locality for CUSE TPM and extend the existing

Implement support for --locality allow-set-locality option that
is primarily useful in cases when the VTPM proxy access is enabled
by file descriptor passing.

Add options for locality handling so that commands in locality
4 for example are rejected per command line parameter. This is
useful when the vTPM is used with containers.
Also implement the custom TPM/TPM2_SetLocality command to allow
the Linux vTPM proxy driver to set the locality in which subsequent
TPM commands will be executed.

Use logprintf wherever possible. While the logging is not set up,
print error messages to stderr and prefix them with 'swtpm: '. After
the logging has been set up all error messages go into the log file.

upon a new line. This prepares for printing every line with
