Added clean source files

sauerbraten/src/enet/ChangeLog

+ENet 1.3.6 (December 11, 2012):
+
+* added support for intercept callback in ENetHost that can be used to process raw packets before ENet
+* added enet_socket_shutdown() for issuing shutdown on a socket
+* fixed enet_socket_connect() to not error on non-blocking connects
+* fixed bug in MTU negotiation during connections
+ 
+ENet 1.3.5 (July 31, 2012):
+
+* fixed bug in unreliable packet fragment queuing
+
+ENet 1.3.4 (May 29, 2012):
+
+* added enet_peer_ping_interval() for configuring per-peer ping intervals
+* added enet_peer_timeout() for configuring per-peer timeouts
+* added protocol packet size limits
+
+ENet 1.3.3 (June 28, 2011):
+
+* fixed bug with simultaneous disconnects not dispatching events
+
+ENet 1.3.2 (May 31, 2011):
+
+* added support for unreliable packet fragmenting via the packet flag
+ENET_PACKET_FLAG_UNRELIABLE_FRAGMENT
+* fixed regression in unreliable packet queuing
+* added check against received port to limit some forms of IP-spoofing
+
+ENet 1.3.1 (February 10, 2011):
+
+* fixed bug in tracking of reliable data in transit
+* reliable data window size now scales with the throttle
+* fixed bug in fragment length calculation when checksums are used
+
+ENet 1.3.0 (June 5, 2010):
+
+* enet_host_create() now requires the channel limit to be specified as
+a parameter
+* enet_host_connect() now accepts a data parameter which is supplied 
+to the receiving receiving host in the event data field for a connect event
+* added an adaptive order-2 PPM range coder as a built-in compressor option
+which can be set with enet_host_compress_with_range_coder()
+* added support for packet compression configurable with a callback
+* improved session number handling to not rely on the packet checksum
+field, saving 4 bytes per packet unless the checksum option is used
+* removed the dependence on the rand callback for session number handling
+
+Caveats: This version is not protocol compatible with the 1.2 series or 
+earlier. The enet_host_connect and enet_host_create API functions require
+supplying additional parameters.
+
+ENet 1.2.5 (June 28, 2011):
+
+* fixed bug with simultaneous disconnects not dispatching events
+
+ENet 1.2.4 (May 31, 2011):
+
+* fixed regression in unreliable packet queuing
+* added check against received port to limit some forms of IP-spoofing
+
+ENet 1.2.3 (February 10, 2011):
+
+* fixed bug in tracking reliable data in transit
+
+ENet 1.2.2 (June 5, 2010):
+
+* checksum functionality is now enabled by setting a checksum callback
+inside ENetHost instead of being a configure script option
+* added totalSentData, totalSentPackets, totalReceivedData, and
+totalReceivedPackets counters inside ENetHost for getting usage
+statistics
+* added enet_host_channel_limit() for limiting the maximum number of
+channels allowed by connected peers
+* now uses dispatch queues for event dispatch rather than potentially
+unscalable array walking
+* added no_memory callback that is called when a malloc attempt fails,
+such that if no_memory returns rather than aborts (the default behavior),
+then the error is propagated to the return value of the API calls
+* now uses packed attribute for protocol structures on platforms with 
+strange alignment rules
+* improved autoconf build system contributed by Nathan Brink allowing 
+for easier building as a shared library
+
+Caveats: If you were using the compile-time option that enabled checksums,
+make sure to set the checksum callback inside ENetHost to enet_crc32 to
+regain the old behavior. The ENetCallbacks structure has added new fields,
+so make sure to clear the structure to zero before use if 
+using enet_initialize_with_callbacks().
+
+ENet 1.2.1 (November 12, 2009):
+
+* fixed bug that could cause disconnect events to be dropped
+* added thin wrapper around select() for portable usage
+* added ENET_SOCKOPT_REUSEADDR socket option
+* factored enet_socket_bind()/enet_socket_listen() out of enet_socket_create()
+* added contributed Code::Blocks build file
+
+ENet 1.2 (February 12, 2008):
+
+* fixed bug in VERIFY_CONNECT acknowledgement that could cause connect
+attempts to occasionally timeout
+* fixed acknowledgements to check both the outgoing and sent queues
+when removing acknowledged packets
+* fixed accidental bit rot in the MSVC project file
+* revised sequence number overflow handling to address some possible
+disconnect bugs
+* added enet_host_check_events() for getting only local queued events
+* factored out socket option setting into enet_socket_set_option() so
+that socket options are now set separately from enet_socket_create()
+
+Caveats: While this release is superficially protocol compatible with 1.1,
+differences in the sequence number overflow handling can potentially cause
+random disconnects.
+
+ENet 1.1 (June 6, 2007):
+
+* optional CRC32 just in case someone needs a stronger checksum than UDP 
+provides (--enable-crc32 configure option)
+* the size of packet headers are half the size they used to be (so less 
+overhead when sending small packets)
+* enet_peer_disconnect_later() that waits till all queued outgoing 
+packets get sent before issuing an actual disconnect
+* freeCallback field in individual packets for notification of when a 
+packet is about to be freed
+* ENET_PACKET_FLAG_NO_ALLOCATE for supplying pre-allocated data to a 
+packet (can be used in concert with freeCallback to support some custom 
+allocation schemes that the normal memory allocation callbacks would 
+normally not allow)
+* enet_address_get_host_ip() for printing address numbers
+* promoted the enet_socket_*() functions to be part of the API now
+* a few stability/crash fixes

sauerbraten/src/enet/docs/FAQ.dox

+/**
+ @page FAQ Frequently Answered Questions
+
+@section Q1 Is ENet thread safe?
+
+ENet does not use any significant global variables, the vast majority
+of state is encapsulated in the ENetHost structure.  As such, as long
+as the application guards access to this structure, then ENet should
+operate fine in a multithreaded environment.
+   
+@section Q2 Isn't ENet just re-inventing TCP?!  What's the point?
+
+In a perfect world, that would be true.  But as many have found, using
+TCP either in lieu of or in conjunction with UDP can lead to all kinds
+of nightmares.  TCP is a good, solid protocol, however it simply isn't
+up to the task of real-time games.  Too much of TCP's implementation
+dictates a policy that isn't practical for games.  If you want to use
+TCP, then do so -- this library is for people that either don't want
+to use TCP or have tried and ended up being discouraged with the
+performance.

sauerbraten/src/enet/docs/install.dox

+/**
+@page Installation Installation
+
+ENet should be trivially simple to integrate with most applications.
+First, make sure you download the latest source distribution here @ref
+SourceDistro.
+
+@section Unix Unix-like Operating Systems
+
+If you are using an ENet release, then you should simply be able to build it
+by doing the following:
+
+./configure && make && make install
+
+If you obtained the package from github, you must have automake and autoconf
+available to generate the build system first by doing the following command
+before using the above mentioned build procedure:
+
+autoreconf -vfi
+
+
+@subsection SolarisBSD Solaris and BSD
+
+When building ENet under Solaris, you must specify the -lsocket and
+-lnsl parameters to your compiler to ensure that the sockets library
+is linked in.
+
+@section Windows Microsoft Windows
+
+You may simply use the included "enet.lib" or "enet64.lib" static libraries. 
+However, if you wish to build the library yourself, then the following
+instructions apply:
+
+There is an included MSVC 6 project (enet.dsp) which you may use to
+build a suitable library file. Alternatively, you may simply drag all 
+the ENet source files into your main project.
+
+You will have to link to the Winsock2 libraries, so make sure to add
+ws2_32.lib and winmm.lib to your library list (Project Settings | Link |
+Object/library modules).
+
+@subsection enet.dsp Building with the included enet.dsp
+
+Load the included enet.dsp. MSVC may ask you to convert it if you
+are on a newer version of MSVC - just allow the conversion and save
+the resulting project as "enet" or similar. After you build this
+project, it will output an "enet.lib" file to either the "Debug/"
+or "Release/" directory, depending on which configuration you have
+selected to build. By default, it should produce "Debug/enet.lib".
+
+You may then copy the resulting "enet.lib" file and the header files
+found in the "include/" directory to your other projects and add it to 
+their library lists. Make sure to also link against "ws2_32.lib" and
+"winmm.lib" as described above.
+
+@subsection DLL DLL
+
+If you wish to build ENet as a DLL you must first define ENET_DLL
+within the project (Project Settings | C/C++ | Preprocessor |
+Preprocessor definitions) or, more invasively, simply define ENET_DLL
+at the top of enet.h.
