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.

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
'_'.

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.

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,

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.
