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.
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.
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.
* 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.

* 'configloader_devel' of git://git.lumiera.org/lumiera/simeon: (24 commits)
Added directive-parser and tests for a content-check of a parsed configitem
Fixed configitem_move, first parsing tests pass now
FIX: Remove llist_move again and put a note to list_relocate, add test
WIP: add config_lookup skeleton
filedescriptor fixup for new copy func in cuckoo
add a custom copy function to the cuckoo hash
fixes after the cuckoo update in filedescriptor.c
Cuckoo hash update
Added two very simple tests for configitem
Typo fix
Fix for section-parser
added section part to parser
parser improvements, compiles now
added CONFIG_SYNTAX errors
typo fix and redundant comment removal
add configitem and configentry to the build system
give the charsets for config keys some constants
fix to make parser mockup compileable, little simplified
WIP: started low-level parser
more functional mockup of the configitem bootstrap
...

* the path parameter given to config_init becomes a registered default
value for 'config.path' itself thus the config system finds its data
path on itself.
* the printf formatting string for representing values are also
bootstrapped as default entries in the config system. This is just a
prelimary example and will be refined later
Fallback to a default in case of a already pending error is not needed.
This would only obtruse error handling. If the default entry would be
erroneous it would be silently ignored and make the thing worse.
a string can be either quoted (single or doublequoted), then the text
between this quotes is returned, quotes are escaped by doubling themself,
no chopping at either end is done,
or not quoted then the the tabs and spaces are chopped from the value
at either end.
even in case of an configuration error the returned value is primed
with the default. The error condition needs still be cleared!
Broken defaults would be unnoticed in case of a double error!
Acquiring mutexes is now wraped in a easy to use MUTEX_SECTION macro.
This scheme will be extended for chained lock propagation soon.
Notes:
* NoBug resourcemanagement is now part of the lower layer,
RESOURCE_ENTER/RESOUCE_LEAVE are maintained automatically
* one must still call RESOURCE_ANNOUNCE/RESOURCE_FORGET, because we want
to maintain high level information about resources.
* MUTEX_SECTIONS must not be left with any kind of jump
lumiera_free() is for now just a static inline wraper around free()
Later this makes it easier to hook in some resource managing functions
or a Garbage Collector in.
Replaced all current uses of free()
Filedescriptors create files at construction, each later access becomes
a reopen on the now existing file.
file_handle_acquire() reopens the file to gain a handle when required
and checks that the file is really the one we expected (ino and dev num)
* add 'backend' for backend global initialization/destruction
and common functions.
* WIP: 'file' acts as interface to named files, provides posix
filehandles with and acquire/release function pair.
* 'filehandle' manages posix filehandles internally, refcounted.
* WIP: 'filehandlecache' keeps unused filehandles in a MRU cache
* WIP: test for filehandle management
* improved filedescriptor test
* make registry initialization singleton, no parameters.
* remove registry init from all functions, has to be called explicitly.
* some nobug improvements
It is now possible to acquire/release filedescriptors for existing files
and files to be created.
Filedescriptors are managed in a registry by refcounts, they get
automatically destructed when the last user releases them.
