This makes sure that our tests run within their own D-Bus session (which
is a requirement most of the time)
As a result, we can get rid of a few workarounds in our CI to setup such
a session.
Don't waste precious CI time reinstalling/upgrading packages.
Most of the scripts here were taken from GLib's CI scripts, but adjusted
to deal with dependencies that might change between branches rather than
different distros.
These changes temporarily fix the fedora:asan timeout error caused
by meson. With allow_failure keyword in place the pipeline will
complete even there is a timeout error in fedora:asan
These changes define the TPM2 API and add its implementations
to the incubation area (egg/).
Summary of the public API:
`egg_tpm2_initialize`: Start a TPM context.
`egg_tpm2_finalize`: End a TPM context.
`egg_tpm2_generate_master_password`: Generate and returns an
encrypted master password in `GBytes` format. TSS Marshaling,
GVariant serialization is used.
`egg_tpm2_decrypt_master_password`: Decrypts a master password
generated from `egg_tpm2_generate_master_password`. TSS
Unmarshaling, GVariant deserialization is used.
TPM2 API: TSS Enhanced System API (ESAPI)
Proposal: [extend file backend to use TPM2 derived encryption keys](https://gitlab.gnome.org/Teams/Engagement/gsoc-2021/-/issues/13)
