Add support for --reconfigure option for the swtpm_setup to be able to
change the active PCR banks. This option only works with --tpm2 and does
not allow to pass several other options such --create-ek or
--create-ek-cert or --create-platform-cert that would alter the state of
the TPM 2 in other ways.

Implement the option --create-config-files to create config files
for swtpm_setup and swtpm-localca for a user account. The files will
be created under the $XDG_CONFIG_HOME or $HOME/.config directories.
This option supports optional arguments 'overwrite' to allow overwriting
existing config files as well as the optional argument 'root' to create
config files under root's home directory. Both options can be passed
by separating them with a ','.

Get rid of the 'c' code that only changed the user and add for support of
the --runas option to change to a different user in the python part.
To get 'make distcheck' to work I needed to name the swtpm_setup python
script with the suffix .in so that it gets copied to the build directory
as swtpm_setup. We need to change execute permissions on this file after
copying.

Switch over to the new python implementation of swtpm_setup. We need to
also adjust test cases that involved the tcsd that otherwise fail for
various reasons. For in-place testing we need to adjust the PYTHONPATH
and PATH so that swtpm_setup.py can be found and so that swtpm_setup.py
then finds swtpm if it is not explicitly passed as parameter.
Adjust the man page for swtpm_setup to reflect the changes.
We now can run swtpm_setup as any user. However, libvirt still runs it
as tss:tss (for example), which is then creating the signing key as tss:tss
as well. Ideally libvirt would run it as tss:root or any other combination
since the tss group may be used for user wanting to access /dev/tpmrm0 for
example. We at least change the directory ownership of /var/lib/swtpm-localca
to tss:root and keep the world out of this directory.

Extend the --print-capabilities option to also report supported RSA
key sizes. Only the TPM 2 may support anything else than 2048 bit RSA
keys, so we only consult 'swtpm socket --tpm2 --print-capabilities'
and grep for 2048 and 3072 key sizes and report them.
If nothing is found, nothing is reported, as before, and 2048 bit RSA
keys should be assumed.
'swtpm_setup --tpm2 --print-capabilities' may now show the following:
{
"type": "swtpm_setup",
"features": [
"cmdarg-keyfile-fd",
"cmdarg-pwdfile-fd",
"tpm2-rsa-keysize-2048",
"tpm2-rsa-keysize-3072"
]
}
Also adjust a test case to use a regular expression for matching
against an expected string that may nor may not have rsa-keysize
verbs.

If the host is missing tcsd (trousers) or the tpm-tools, swtpm_setup
will now report the 'no-tpm12-tools' verb like this:

{
"type": "swtpm_setup",
"features": [
"cmdarg-keyfile-fd",
"cmdarg-pwdfile-fd",
"no-tpm12-tools"
]
}
The only TPM 1.2 setup parameter that requires interaction with
the TPM 1.2 that can be pass is then '--createek'.
