An apparmor profile was added for Debian-based distributions in order to
increase security. This blocks swtpm from accessing restricted and unnecessary
files, folders, and network interfaces. swtpm works as normal alongside libvirt
and its configurations, however users may run into issues when using swtpm on
its own when providing it with a restricted directory. The apparmor profile can
be modified to include additional permissions by creating and adding to the
file /etc/apparmor.d/local/usr.bin.swtpm.

Currently `trousers` is listed as (hard) Dependency, but it does not
seems to be required for quite a few usecases, e.g., ours where we
mainly using swtpm for providing a tpm to VMs.
With trousers in Debian one gets an additional pain point: it comes
with rather dated and in some cirumstances failing by mistake init
script [0] that can throw errors when setting up during installation
and thus fail the whole installation of swtpm as Debian policy for
`Depends` hits:
> A package will not be configured unless all of the packages listed
> in its Depends field have been correctly configured
-- [1]
Declaring dependencies for things are not a hard requirement means
that a user will be required to install more dependencies than
actually needed.
Just documenting that as fact why I investigated in the
hard-requirement on trousers in the first place, not an actual
justification - it's a packaging bug after all.
So downgrade the dependency to "Suggests", as it seems a reasonable
level when checking its documented meaning:
> This is used to declare that one package may be more useful with
> one or more others. Using this field tells the packaging system and
> the user that the listed packages are related to this one and can
> perhaps enhance its usefulness, but that installing this one without
> them is perfectly reasonable.

- debian/clean: Add files that were not being automatically cleaned
up by dh(1)'s `clean` target.
- debian/control:
- Add new recommended/required fields and bump Standards-Version.
- Remove redundant build dependencies that are implied transitively.
- Bump debhelper dependency version to match debian/compat.
- Move swtpm-libs's ${misc:Pre-Depends} dependency to `Pre-Depends`.
Resolves `depends-on-misc-pre-depends` Lintian warning.
- Sort packages and dependency lists alphabetically as per
wrap-and-sort(1).
- debian/not-installed: List deliberately non-installed files to
avoid dh_missing(1) warnings.
- debian/rules:
- Pass --no-scripts to dh_makeshlibs(1) in order to keep a
ldconfig(8) trigger from being implicitly added, which for
this package was redundant and triggered Lintian warning
`package-has-unnecessary-activation-of-ldconfig-trigger`.
- Remove redundant --parallel dh flag.
- Remove redundant dh_usrlocal override.
- debian/*.install:
- Add swtpm-create-tpmca(8) and its manpage, which were missing.
- Remove redundant `#! /usr/bin/dh-exec` lines.
- Sort entries alphabetically as per wrap-and-sort(1).
- debian/swtpm-tools.postinst.in: Add `set -e` to fail in case of
error. Fixes `maintainer-script-ignores-errors` Lintian warning.

This is a 1:1 rewrite of swtpm_localca in 'C' as a final step to get
rid of the python dependency. It addresses issue #437.
Tested on: Cygwin, Fedora 33, Ubuntu Xenial & Bionic, FreeBSD,
DragonFlyBSD, OpenBSD (i386), Mac, Debian (recent), Centos-8,
CentOS (recent), Alpine (recent), OpenSUSE (recent),
Fedora 28 PPC Big Endian

The only place where pip is required is in src/swtpm_setup/Makefile.am, l. 48,
to uninstall a manually built package. Most people will have pip already
installed, since it comes bundled with Python by default. It might not be
installed by default in minimal build environments used for distribution
packaging, but these rely on the file tracking by a package manager instead of
using "make uninstall".
In conclusion, I think requiring pip is only helpful for a very limited number
of people, and is just a superfluous build dependency for distribution
packagers. Issuing a warning that the package cannot be uninstalled cleanly if
pip is not found seems enough.

Remove tpm-tools from runtime dependencies. Keep trousers for the
creation of the 'tss' user for now. Add python related dependencies.
Adjust the directory ownership for /var/lib/swtpm-localca to tss:root and
the mode flags to 0750. The new CA now may still be created as tss:tss but
users in the tss group will not have access to it.

Use SoftHSM to create a pkcs11 URI and then use the pkcs11 URI
to sign the certificate of a TPM 2.0 with this key using swtpm-localca.
This test case works with softhsm >= 2.3.0 on Fedora and should work
with a recent version of Ubuntu. If an error is encountered setting
up the softhsm2 environment, we just skip the test.

Rather than sending two separate messages with the bare python 2
API, use the python twisted package to send the control and data
in one sendmsg() call. This avoids occasional test failures in
the ctrlchannel test case that is currently sending the data and
control part of the message in 2 steps, which can lead to the
recpient not seeing the whole message.
Add python-twisted as a build dependency to the rpm and Debian
builds and the .travis.yml.
