5bbe80b370 preliminary use of the config system for some settings
* backend.filehandles maximum filehandles used
 * backend.mmap_window_size mapping window start size
 * backend.as_limit address space limit

This needs to be changed to use the lumieraorg_configuration interface.

e938b36071 WIP: mmap management first go
Quite some code which was hold back in favor of the config and plugin stuff
implements:

 * mmapcache: mru cache for unused memory mappings
 * mmap: single mmaped areas
 * mmapings: manages mmaps established for one filedescriptor

aae3c8ed81 LUMIERA_PLUGIN is dead, long life LUMIERA_PLUGIN
removes the difference in compiled in and plugin interfaces.
 * All interfaces are now defined with LUMIERA_EXPORT(...)
 * The definition of LUMIERA_PLUGIN at compile time takes action to compile
   as plugin which gets automatically managed.
 * compiled in (core) interfaces need still be registered, this is
   simplified with the LUMIERA_INTERFACE_REGISTEREXPORTED and
   LUMIERA_INTERFACE_UNREGISTEREXPORTED macros which become no-ops for
   plugins.

fa6b6d54e9 hook the plugin refcounting in
The plugin refcounter is driven from interface opening/closing, this is
quite internal.

The 'last' time in plugin now records the last time the refcounter dropped
to 0, this is just sufficient enough to find out how long a plugin is
unused.

7afce647fb few tool functions for the plugin implementation
* plugin_name() to figure out the name of the plugin
 * plugin_refinc() and plugin_refdec() to manage the refcount

c26cd391b0 automatic plugin unloading at interfaceregistry_destroy()
All open plugins will be unloaded when the registry gets destroyed.
If there are still interfaces open, this will assert at ALPHA builds.

3155ae068f Loading of dynamic modules

7c2415838b WIP: big plugin update
* fix configure.ac to check for dlopen, introduce $(LUMIERA_PLUGIN_LIBS)
 * Generic pluginloader finished, all plugins get loaded and registered at
   start for now, it is prepared for on-demand loading and unloading but
   not implemented because that needs the plugindb.
 - plugin unloading not yet finished, this asserts at the end

c30c98bebd add a LUMIERA_INTERFACE_CLOSE macro
This is a small typesafe wrapper around the interface_close() function
and since we need INTERFACE_OPEN wraped too this makes it more orthogonal

4d2fe242d0 Some more interfaces improvements
* add a lumiera_interface_version() function for runtime type and version
   checking of interfaces
 * the 'lumieraorg__plugin' interface is now private
 * add a macro to construct a interface instance name string

2342c3a87a New Plugin implementation
* plugin{.h,.c} are back but work in progress
 * the interfaceregistry also manages a pluginregistry, makes no much sense
   to isolate it yet, both share a mutex and are commonly used together

48778cf3d7 WIP: new plugin.h header
This ditches the old 'proof of concept' implementation, interfaces and
plugins are internally separate now and publically only accessed over
the 'interfaces' api.

The interface registry now gets an additional 'plugin' member to
backreference plugins from interfaces.

7be18d6344 Adding explicit delimiters to the config wordlist feature

b242f3359b Fix/Wip: LUMIERA_PLUGIN definition
There where some bugs slipped in (not yet tested code)

removed the descriptor from the plugin itself, lets see if we can remove
the acquire and release functions later too.

Declare the plugin interface itself in its first experimental state

99e3e79fe6 Complete the interface descriptor declaration
After a discussion with ichthyo and some further thinking this should be
mostly finished now. Nevertheless it is still experimental until we gain
experience with it.

f7fa5769ca Start of a 'wordlist' type for the config subsystem
wordlists are simple not quoted words delimited by semicolon, tab, space or
commas. Some special functions will allow to access each of this words by
index etc.

0cf7dec793 Interfaceregistry for 'active' interfaces
All interfaces which are available get registered in a tree.
This will be used internal for lookup interfaces. The higher level calls
will be an	amalgamation of this lookup and the upcoming plugindb and
loader.

f05f6772f1 Interface system refactoring
* lumiera_interface are now static structures, never wrritten
 * introduced a lumiera_interfacenode which manages the dynamic data
   of interfaces. The interfaceregistry now holds this nodes.
