For sys_dependencies.h to be found during out-of-tree builds we
need to include -I$(top_srcdir)/include.

OS/X also does not have a proc filesystem, so we use the '_'

The daemon() call is deprecated on OS X. This patch works around it so
that we can compiled with -Wall -Werror and still can use the daemon()
call while avoiding compiler errors due to this function's deprecation
marking in stdlib.h.

Make swtpm_setup.sh work on FreeBSD.
A common fix for the problem related to echo stopping to write
data into a socket after the first occurrence of \x0a sees to
write it into a pipe and cat the data from there.

The OpenBSD stat tool uses -f%z to return the file size in bytes.
So we wrap stat in get_filesize and call it with different parameters
depending on the system.

On OpenBSD 6.2 we have an older version of od that does not support the
-w parameter. Also we have to use the bash echo there since /bin/echo
does not support the -e parameter. We are using /bin/echo on the other
systems since there was (once) a bug when \x0a had to be converted to a
hex number.

OpenBSD does not have a proc file system from which we could
determine the path that swtpm_setup was run from and where we
expect swtpm_setup.sh to be located in as well. Using getenv("_")
seems to work as a replacement in the OpenBSD case.

Get rid of the dependency on netstat so that we can at least support
swtpm_setup with TPM 2 on Cygwin and BSD later on. This is the first
step into this direction.

Check that the netstat tool, which may not be required to be installed,
is indeed installed and usable with a set of command line options.
If this tool is not installed it may end up causing swtpm_setup to
hang forever.

Implement --pcr-banks to allow a user to choose the set of active

Remove the -s parameter to tpm2_nv_define since it was causing
