Michael Catanzaro 33c9c305e3 Improve documentation of g_tls_database_verify_chain() 
It is critical to mention how the identity parameter is expected to be
handled. In particular, if identity is not passed, then the identity of
the server certificate will not be checked at all. This is in contrast
to the connection-level APIs, which are supposed to be fail-safe. The
database and certificate-level APIs are more manual.

/**
* g_tls_database_verify_chain:
* @self: a #GTlsDatabase
* @chain: a #GTlsCertificate chain
* @purpose: the purpose that this certificate chain will be used for.
* @identity: (nullable): the expected peer identity
* @interaction: (nullable): used to interact with the user if necessary
* @flags: additional verify flags
* @cancellable: (nullable): a #GCancellable, or %NULL
* @error: (nullable): a #GError, or %NULL
*
* Determines the validity of a certificate chain after looking up and
* adding any missing certificates to the chain.
*
* @chain is a chain of #GTlsCertificate objects each pointing to the next
* certificate in the chain by its #GTlsCertificate: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 #G_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 ensure the server certificate is valid for
* the expected peer identity. If the identity does not match the
* certificate, %G_TLS_CERTIFICATE_BAD_IDENTITY will be set in the
* return value. If @identity is %NULL, that bit will never be set in
* the return value. The peer identity may also be used to check for
* pinned certificates (trust exceptions) in the database. These may
* override the normal verification process on a host-by-host basis.
*
* Currently there are no @flags, and %G_TLS_DATABASE_VERIFY_NONE 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
* %G_TLS_CERTIFICATE_GENERIC_ERROR 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 g_tls_database_verify_chain_async() to perform
* the verification operation asynchronously.
*
* Returns: the appropriate #GTlsCertificateFlags which represents the
* result of verification.
*
* Since: 2.30
