e6bd1586d6 Replace glibc tsearch() with a custom red-black tree implementation. 
The library supplied tree estructure is not enought for our needs, due to its
limited API. Thus, we have implemented a suitable red-black tree.

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 
directory.

411524c330 Handling of iso directory depth restrictions on tree creation time. 
Note that this doesn't involve the RR reparent. It just ignore the files 
that break iso restrictions (see ECMA-119, 6.8.2.1).

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.

dd83f85d09 Support for identification of source Streams. 
We identify uniquelly a given source Stream by a triple of numbers: the
filesystem id, the device id inside the filesystem, and the inode id.

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.
