778e39ba3c Take care about the RR entries when computing the size, and cache it. 
When computing the size of the directory structures, take care about the size
taken by the RR/SUSP fields. Also, cache that size, otherwise we need to do
this computation several times and it is ugly, because the CE entries need to 
know where the Continuation Area will be stored.

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.

2ab23693db Replace path table size computation by a recursive version. 
The recursive version wastes less memory, as it doesn't need the path table
array.

42731f4135 Fix bug in create tree, to propertly handle ignored files. 
Due to a bug, when a file was ignored (for example, a dir whose deep 
level was greater than 8), all its parents where ignored, what causes 
root to be ignored!

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.
