Malcolm Robb a82df07c0c Version 1.09.0608.14
Release of COAA PlanePlotter MLAT and SMU support for RPi

ppup1090 now supports Ground Stations functions required for MLAT and
SMU operation. This is *ONLY* available for RPi and similar linux
hardware.

Also included are sample startup scripts for dump1090 only and
dump1090+ppup1090 together.

A few minor additions and bug fixes as detailed below

1) Additional command line option "--net-buffer <n>" to specify the TCP
output buffer size. Default is n=0, which is 64Kb. Specify a value of n
to increase the buffer size according to  Size  = 64Kb * 2^n, so an n of
1 = 128Kb, n=2 is 256Kb etc. n is limited to 7, so the max size is 8Mb.
This option may assist if you have a high number of aircraft being
received, and an unreliable network connection, or if the receiving end
can be busy for an extended time.

2) Bug fix in ppup1090 which prevented the uploading of valid
ModeA/Squawk codes

3) Bug fix per Markus Grab's commit.

Malcolm Robb 30ae45ec2b Windows Version of dump1090
Make the modifications necessary to compile dump1090 for WinXP, Win7 and
hopefully Win8.

The files can be compiled using M$ Visual Studio/C++ 6.0. Due to various
licensing issues, I haven't included the libraries or DLLs. You will
need to locate pthreadVC2.lib and rtlsdr.lib to link the file, install
the zadig drivers to support the dongle, and locate libusb-1.0.dll,
msvcr100.dll, pthreadVC2.dll and rtlsdr.dll.

dump1090.exe will not run on any Windows version prior to XP SP2,
because msvcr100.dll imports several functions from the Windows kernel
that are not available on earlier versions. This means dump1090 won't
work on Win2K.

The major change to the code relates to file handles. The original code
assumes Linux behaviour in that handles are allocated from 0
sequentially upwards. However Windows handles are allocated pseudo
randomly, and handle numbers greater than 1024 would break the code. The
code has therefore been modified to use a linked list of connection
structures, rather than a static array limited to 1024 entries.

Malcolm Robb f7843c1691 Implement TCP Heartbeat
Some users have reported issues where the TCP link to dump1090 can be
lost at times of low traffic density - typically in the middle of the
night. One possible reason for this is that some routers drop the link
if there is no traffic for a predetermined period.

To try and resolve this, dump1090 now sends a 'null' packet consisting
of 7 "0x00" bytes approximately once a  minute if there is no real
received traffic during this time. This packet should be discarded by
the application receiving the dump1090 because it will have an invalid
checksum, and ICAO address 0x000000 is also invalid. However, this null
packet should be enough to keep routers alive.

Malcolm Robb f3b5167a0a Create separate Makefiles
Create separate makefiles for dump1090, view1090 and ppup1090. These can
be run with the command line "make -f makedump1090", "make -f
makeview1019" and "make -f makeppup1090"

Pass dump1090 version number into ppup1090 uploader so that coaa1090.obj
doesn't need re-compiling between versions.

Remove ppup1090 from general Makefile - it's not intended for anything
other than RPi, so gives linker errors on other (non Linux raspian)
systems.
