Lcm

This release introduces experimental support for C / .NET, provided by
Jan Hrbáček. Bug reports and patches are greatly appreciated.

This release also introduces a small python API change, and renames a program
in windows.

Additional bugfixes are included.

- Windows
- Now builds lcm-gen.exe, not lcmgen.exe
- .NET
- The lcm-dotnet/ directory contains a publish-subscribe library for
.NET applications.
- lcm-gen
- (C) A new set of options are available for generating C bindings
- (Python) change `__init__.py` import statements. If a package named 'proj'
contains the LCM type msg_t, then the `__init__.py` file now contains:

from msg_t import msg_t

and the recommended usage pattern is:

import proj
instance = proj.msg_t()

- (Windows, Java) fix pathname bug
- Other
- minor build system bugfixes

============

This is a bugfix and maintenance release.

Updated documentation for single host use, to describe how to use LCM over the
localhost interface.

- C
- fix leaking file descriptors
- fix OS/X compile bug for lcm-example (missing include <sys/select.h>)
- simplify project include path requirements in Windows
- update error checking, messages for single host use (Linux)
- Java
- expose encode/decode methods for advanced users
- lcm-gen
- (C) add --c-no-pubsub command line option to lcm-gen to generate C language
bindings without a dependency on liblcm (useful if only the marshalling
aspect of LCM is desired).
- (Java) don't complain about default pkg if one is specified on cmd line.
- lcm-spy
- remember last message on each channel so that object panels open up
immediately.
- put frames in front when double clicked.
- Other
- remove manpage-specific GFDL copyright notices.

enhancements.

============

- Java
- Faster serialization classes that provide a 4x-5x speedup. This introduces
a backwards-incompatible change to the LCM Java API. Specifically, the
`messageReceived()` method of the LCMSubscriber interface has changed from:
public void messageReceived(LCM lcm, String channel, DataInputStream ins)
to
public void messageReceived(LCM lcm, String channel, LCMDataInputStream ins)
LCMDataInputStream has an almost identical API to DataInputStream, and
migration of source code to the new API should only require changing
implementations of LCMSubscriber in the manner described above.
- C
- warn on Linux if large packets are being received but the kernel rbuf is
small
- Python
- bugfix for decoding arrays of bytes
