94e687d9d3 Add a ring buffer implementation.
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.

9e9c077c6e Minimize charset conversion errors, ignoring when we can't do better.
If a file name is encoded in a different encoding than default input, current
implementation make image generation to be cancelled. As this can happen quite
frequent, due to files from discs or Windows partitions incorrectly mounted,
the best we can do is just ignore this, replacing the wrong character with a

35ef22cdd7 Implement ECMA-119 burn_source and writer thread handling.
At this time, nglibisofs is able to output an image!! Note that communication
between writer and read thread is done via a pipe. That will be replaced by a
ring buffer in the near future.

42731f4135 Fix bug in create tree, to propertly handle ignored files.

root to be ignored!

The library supplied tree estructure is not enought for our needs, due to its

39bde82ff6 Move size, ino, dev cache from IsoFileSrc to IsoStream.
That is a better decission, as it reduces the number of stat() call 
needed, and anyway some Streams will need the size.

c03d4d9b33 Implementation of name mangling algorithm.
This has to ensure that file names are unique among all files in an iso 
directory. Current implementation can be improved by using a hash table 
to keep the names, instead of iterate over all children. An alternative 
method, keeping children sorted all the time, thus allowing binary 
search, has been considered but discarded.                          

Current implementation support up to 9,999,999 equal files per

40b27dbacc Initial support for low level ECMA-119 tree.
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.

aa312cf7d7 Fix bug in IsoFileSrc implementation, related to a wrogn usage of tsearch.
It happens that tsearch seems to not return a pointer to the inserted element,
but a pointer to a pointer to the inserted element (that makes sense, as we
are inserted pointers...). This bug, thus, was related to a wrong 
understanding of the tsearch API!

7b241176fb Init implementation of IsoFileSrc.
Ecma119Image, defined for first time in this commit, is the context for image 
written. It keeps the low level objects needed during image written.

IsoFileSrc is the low level object that takes care about the info needed to
write file contents to image. It takes care about reading from Stream in 2K
block chunks. To prevent the same file be written twice to image, we keep in
Ecma119Image a search tree, indexed by the triple key (fs, device, inode) that
uniquelly identifies a source.

d10ed353e2 Implement function to recursively add a dir to an iso tree.
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.
