@brief Functions to save and retrieve passwords.
@author Copyright (C) 2010 Geert Janssens <janssens-geert@telenet.be>
GnuCash needs passwords for some of the services it uses, like
connecting to a remote database, or bank. For security these passwords
shouldn't be stored unless in an encrypted password store. This is
implemented for example in Gnome's keyring or Mac OS X' keychain.
This file defines some convenience functions to store a password
or to retrieve one.

/** Attempt to store a password in some trusted keystore. At this point
* that can be Gnome's keyring or Mac OS X' keychain. If no
* such keystore is available, this function does nothing.
*
* All the parameters passed (except for the password) will be
* used to create a unique key, so the password can later be
* retrieved again with the same parameters.
*
* @param access_method Service type the user attempts to access. Can
* things like 'mysql', 'postgres' and so on.
* @param server Server the user wishes to connect to.
* @param port Port the service listens on. If set to 0, it will
* be ignored in the search for a password.
* @param service The service the user wishes to access on the server.
* This can be a database name or a path.
* @param user The username to access the service.
* @param password The password to access the service.

/** Attempt to retrieve a password to connect to
* a remote service. This is deliberately generic: the remote
* service can be a database, website, anything.
*
* If a trusted keystore infrastructure is found (such as the
* Gnome's keyring or Mac OS X' keychain) this infrastructure
* will be queried first.
*
* If no such infrastructure is available or the query didn't
* return a valid result, the user will be prompted for his
* password.
*
* @warning When the user is prompted for a password, he can also
* change the username. So whenever you call this function, read
* both the username and password values before you continue !
*
* @param parent Used to transition from in case the user is prompted
* for a password.
* @param access_method Service type the user attempts to access. Can
* things like 'mysql', 'postgres' and so on.
* @param server Server the user wishes to connect to.
* @param port Port the service listens on. If set to 0, it will
* be ignored in the search for a password.
* @param service The service the user wishes to access on the server.
* This can be a database name or a path.
* @param user The user name to access the service. Remember, although
* you pass it to search for the password, it can have
* changed when the function returns.
* @param password The password to access the service.
* @return a boolean indicating whether or not a valid password
* has been retrieved. The function will return FALSE
* when the user explicitly cancels the password dialog or
* if it wasn't called properly. Otherwise it wil return
* TRUE.
*
* access_method, server, port, service and user will be the parameters
* passed to the trusted keystore (if available) to find the unique
* password for this service.
