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.

Use a buffer for printing in TPM_PrintAll. Emit the buffer
upon a new line. This prepares for printing every line with

Wait for the chardev the VTPM proxy device creates to actually appear.
In some cases the exec statement opening the file would otherwise
create a file /dev/tpm0 for example and subsequently tests then ended

Introduce a log level for the logging functions. The log level
is defined by the number of spaces used for indentation. Adapt
the log functions to only log when the number of leading spaces
in a string is appropriate for logging.
Call the log function of libtpms to set the file descriptor to
log to, the log level, and log line prefix.
