libdvdcss: drop internal libdvdcss tree

Browse Source 
The internal libdvdcss version was only compiled if you used internal
libdvdread too; and libdvdread was not included in the sources, so
that'd only happen if you manually added libdvdread in the build
tree. Keeping libdvdcss for that case probably isn't worth it, so
delete it from the tree. The build system part is still there, so an
internal build is possible if you add the directory back.

/**
* \mainpage libdvdcss developer documentation
*
* \section intro Introduction
*
* \e libdvdcss is a simple library designed for accessing DVDs like a block
* device without having to bother about the decryption. The important features
* are:
* \li portability: currently supported platforms are GNU/Linux, FreeBSD,
* NetBSD, OpenBSD, BSD/OS, BeOS, Windows 95/98, Windows NT/2000, MacOS X,
* Solaris, HP-UX and OS/2.
* \li adaptability: unlike most similar projects, libdvdcss doesn't require
* the region of your drive to be set and will try its best to read from
* the disc even in the case of a region mismatch.
* \li simplicity: a DVD player can be built around the \e libdvdcss API using
* no more than 4 or 5 library calls.
*
* \e libdvdcss is free software, released under the General Public License.
* This ensures that \e libdvdcss remains free and used only with free
* software.
*
* \section api The libdvdcss API
*
* The complete \e libdvdcss programming interface is documented in the
* dvdcss.h file.
*
* \section env Environment variables
*
* Some environment variables can be used to change the behaviour of
* \e libdvdcss without having to modify the program which uses it. These
* variables are:
*
* \li \b DVDCSS_VERBOSE: sets the verbosity level.
* - \c 0 outputs no messages at all.
* - \c 1 outputs error messages to stderr.
* - \c 2 outputs error messages and debug messages to stderr.
*
* \li \b DVDCSS_METHOD: sets the authentication and decryption method
* that \e libdvdcss will use to read scrambled discs. Can be one
* of \c title, \c key or \c disc.
* - \c key is the default method. \e libdvdcss will use a set of
* calculated player keys to try and get the disc key. This can fail
* if the drive does not recognize any of the player keys.
* - \c disc is a fallback method when \c key has failed. Instead of
* using player keys, \e libdvdcss will crack the disc key using
* a brute force algorithm. This process is CPU intensive and requires
* 64 MB of memory to store temporary data.
* - \c title is the fallback when all other methods have failed. It does
* not rely on a key exchange with the DVD drive, but rather uses a
* crypto attack to guess the title key. On rare cases this may fail
* because there is not enough encrypted data on the disc to perform
* a statistical attack, but in the other hand it is the only way to
* decrypt a DVD stored on a hard disc, or a DVD with the wrong region
* on an RPC2 drive.
*
* \li \b DVDCSS_RAW_DEVICE: specify the raw device to use. Exact usage will
* depend on your operating system, the Linux utility to set up raw devices
* is \c raw(8) for instance. Please note that on most operating systems,
* using a raw device requires highly aligned buffers: Linux requires a
* 2048 bytes alignment (which is the size of a DVD sector).
*
* \li \b DVDCSS_CACHE: specify a directory in which to store title key
* values. This will speed up descrambling of DVDs which are in the
* cache. The DVDCSS_CACHE directory is created if it does not exist,
* and a subdirectory is created named after the DVD's title or
* manufacturing date. If DVDCSS_CACHE is not set or is empty, \e libdvdcss
* will use the default value which is "${HOME}/.dvdcss/" under Unix and
* "C:\Documents and Settings\$USER\Application Data\dvdcss\" under Win32.
* The special value "off" disables caching.
