It will default to input charset (i.e. the locale charset for now).
Names will be stored internally in that locale charset. Note that input
charset musn't be changed by user. Instead, we can provide an input
charset property to IsoFilesystem implementations.
This is intented to replace the pipe between the writer and reader
threads. That way we can have a much better control of cancelation
situations. Still to be optimized.
This only adds the tree creation functions, no sorting and name mangling
yet. Only plain ECMA-119 supported for now, nor RR, relaxed
restrictions, etc..
This also adds a little test program.
This commit also to the following changes:
- create_node() on builder never frees the IsoFileSource, it is responsability
of the caller to free it.
- Recursive addition options added to IsoImage (not exposed to public API yet)
- create_node() takes care about follow_symlinks
- Added little demo program to test it.
