Implement the --profile-remove-fips-disabled option that is used to tell
swtpm to remove algorithms that are disabled by FIPS mode on the host.

Add a test cases passing this option and check that the resulting profiles

Test cases using swtpm_localca were failing because swtpm_localca
now picked up the swtpm_cert installed in /usr/bin/swtpm_cert rather
than the one in the PATH. This revert fixes the issue and users will
have to adjust their PATH for out-of-PATH installations.

To support install paths that are not covered by $PATH, and still allow
swtpm_setup and swtpm_localca to find swtpm and swtpm_cert executables,
implement find_program() to prepend the install path if only the program
name is given and otherwise fall back to g_find_program_in_path().
Update the man page stating that swtpm from the installation directory
(BINDIR) is tried to be used before one is attempted to be found in
the PATH.

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

the TPM 2 in other ways.

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

"cmdarg-keyfile-fd",
