private key. The root CA's key password can be set using the environment
variable SWTPM_ROOTCA_PASSWORD.

This (experimental) script uses GnuTLS tpmtool to create a TPM 1.2
intermediate CA that can sign a vTPM's EK and platform certificates.
Add a man page for this tool.

GnuTLS can use TPM 1.2 keys for signing. For this we just need to support
key URLs in the GnuTLS format:
tpmkey:uuid=...
tpmkey:file=...
We don't try to read these URLs as files but pass them through as URLs to
the swtpm_cert tool that will then try to sign with the TPM 1.2 key by
passing the URL to GnuTLS API calls.

OS/X has a flock (v0.2.3) implementation using
brew tap discoteq/discoteq
brew install flock
The current version doesn't support -x as a parameter for
an exclusive lock but uses an exclusive lock when no parameter
is passed at all.

To avoid clashes with the lock files created by swtpm, have
swtpm-localca creata a lock file with the name .lock.swtpm-localca
so they can share directories if necessary.
This patch makes tests/test_tpm2_swtpm_setup_create_cert run on
OpenBSD since the swtpm and swtpm-localca then do not interfere
with the file locks. This doesn't seem to be an issue on Linux
or Cygwin, though, where probably the file locking is implemented
differently.

OpenBSD uses an older sed implementation that doesn't understand the
meaning of the '+' for getting one or multiple occurrences of a letter.
Work around this by not using it and trimming white spaces at the end
of a variable using bash.
Use 100 as file descriptor rather than 200 to accomodate OpenBSD,
which only support file descriptors <= 127.

Cleanse the tmp variable before running eval on it. This is to prevent
execution of commands that a hidden in variable values read from a config
file. We only need to resolve the values of variables and don't want
the execution of a subshell command initated by either $(...) or `...` .

We are currently missing the Authority Key Id in the certificate used for
creating the EK cert. To get this, we create a root CA for our local CA
and use that root CA to sign the local CA's certificate. Our local
CA is now an intermediate CA and the Authority Key Id can now be copied
into the EK cert.
