settings: introduce extended groups concept
PATCH v7 1/2 settings: introduce extended groups concept
This patch introduces a new extended format for settings files. This new format allows raw data to be provided under a given group rather than key/value pairs. A group using an extended format will contain both the extended type and group name in the format, for example:
[@pem(a)certificate]
Where 'pem' is the type and 'certificate' is the name. The type of format requires an extension specific parser implementation in settings as the parser must know when to start/stop parsing data. This allows for any textual characters to be present after the group is declared, including special characters like [] (its completely up to the parser to decide whats valid and what is not).
Three new l_settings APIs were added:
l_settings_has_embedded_groupl_settings_get_embedded_groupsl_settings_get_embedded_value
In this patch, the 'pem' extension type is also introduced, and for now is the only extended type. The pem extended type expects a base64 encoded PEM (or list of PEMs) after the group. The pem parser will stop after the last PEM is found. Examples can be found in unit/test-settings.c
