'GI.Gio.Objects.TlsDatabase.TlsDatabase' is used to lookup certificates and other information
from a certificate or key store. It is an abstract base class which
TLS library specific subtypes override.

A 'GI.Gio.Objects.TlsDatabase.TlsDatabase' may be accessed from multiple threads by the TLS backend.
All implementations are required to be fully thread-safe.

Most common client applications will not directly interact with
'GI.Gio.Objects.TlsDatabase.TlsDatabase'. It is used internally by 'GI.Gio.Objects.TlsConnection.TlsConnection'.

Determines the validity of a certificate chain after looking up and
adding any missing certificates to the chain.

/@chain@/ is a chain of 'GI.Gio.Objects.TlsCertificate.TlsCertificate' objects each pointing to the next
certificate in the chain by its 'GI.Gio.Objects.TlsCertificate.TlsCertificate':@/issuer/@ property. The chain may initially
consist of one or more certificates. After the verification process is
complete, /@chain@/ may be modified by adding missing certificates, or removing
extra certificates. If a certificate anchor was found, then it is added to
the /@chain@/.

/@purpose@/ describes the purpose (or usage) for which the certificate
is being used. Typically /@purpose@/ will be set to 'GI.Gio.Constants.TLS_DATABASE_PURPOSE_AUTHENTICATE_SERVER'
which means that the certificate is being used to authenticate a server
(and we are acting as the client).

The /@identity@/ is used to check for pinned certificates (trust exceptions)
in the database. These will override the normal verification process on a
host by host basis.

Currently there are no /@flags@/, and 'GI.Gio.Flags.TlsDatabaseVerifyFlagsNone' should be
used.

If /@chain@/ is found to be valid, then the return value will be 0. If
/@chain@/ is found to be invalid, then the return value will indicate
the problems found. If the function is unable to determine whether
/@chain@/ is valid or not (eg, because /@cancellable@/ is triggered
before it completes) then the return value will be
'GI.Gio.Flags.TlsCertificateFlagsGenericError' and /@error@/ will be set
accordingly. /@error@/ is not set when /@chain@/ is successfully analyzed
but found to be invalid.

This function can block, use 'GI.Gio.Objects.TlsDatabase.tlsDatabaseVerifyChainAsync' to perform
the verification operation asynchronously.
