calling 'luidgen' with a list of filenames replaces the word LUIDGEN in
each of this files with a octal escaped string consisting a unique
identifier
add luid formatter help macros to luid.h
let compilation of files which contain the word 'LUIDGEN' fail with a
hopefully self-explaining error message
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.
This *must* be replaced by a real luid with a upcoming luidgen tool ASAP,
luids starting with zeros are invalid. For the time until this luidgen tool
is not ready we just leave it this way. Later it will be changed to give a
compile error.
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.
When interfaces cross depend on each other nested acquiring from
their acquire handlers would introduce cyclic references which cant
be cleaned easily. By flagging such nested acquisitions as weak the
respective handler functions can account for this.
Example: maintain 2 ref counters one for strong and one for weak
acquisitions. At release time all acquired nested handles get closed when
the strong counter drops to zero, which causes that cross reference
releases will eventually drop the weak count to zero too. Then all
resources can be freed and the interface is properly shut down.
