Ondřej Hruška 7cdab61d72 Schedule encoding/decoding (#319)
* schedule: add decode_daily_schedule() and encode_daily_schedule()

* schedule: encode/decode implemented + add to bacapp

* add safe encode/decode functions for timevalue, schedule function renaming

* fix unit tests build failing

* add IDEA and test temporary files to .gitignore

* try to make "deprecated" work in MSVC

* add WeeklySchedule compare function

* add bacnet_weeklyschedule_context_decode()

* Add basic test for WeeklySchedule

* Fix WeeklySchedule parsing and snprintf, decoder verified with real hardware

* try to fix windows build

* improve boolean parsing in 'bacapp_parse_application_data'

* add parse function for weekly schedule

* allow types > 16 in bacwp, show the decoded value before sending

* add bacapp binaries to gitignore

* remove bacwp logging

* Add error checking to bacapp_parse_application_data

* try to fix windows build

* fix avr build

* Fix error handling in RP Ack

* add singleDay flag

* show day name in single day weeklyschedule snprintf

* show weeklyschedule inner tag in snprintf

* improve weeklyschedule parsing and printing, supports type names now

* add weekly schedule to bacapp_decode_data

* move bacnet/bacnet_plat_compat.h to bacnet/basic/sys/platform.h

* disable tag limit also in bacwpm

* add ifdef's around strtoX helper functions in bacapp

* move strtox to BACAPP_PRINT_ENABLED ifdef in bacapp

* fix stm32 makefiles

* fix at91sam7s build

* use BACNET_UNSIGNED_INTEGER in BACnet_Short_Application_Data_Value

* fix capitalization in BACnet_Daily_Schedule

* add name to BACNET_TIME_VALUE struct

* change bacwp bacwpm to use bacapp_known_property_tag()

* fix some macros in bacdcode missing parentheses

* Remove dummy fields from BACNET_SHORT_APPLICATION_DATA_VALUE, replace remaining uses of upcasting (adds extra overhead but is maybe safer), rename short DV to Primitive

* fix new ci warnings

* more fixes for ancient C

* fix tests no longer building

* primitive value renamed to shorter name

This port was done with a AT91SAM7S-EK which contained a
AT91SAM7S64 processor.  The compiler was the GNU ARM compiler
and tools from Yagarto project.  

The hardware was modified by severing the I-PA5 (RXD0), 
I-PA6 (TXD0), I-PA7 (RTS0) pads and rerouting those 
signals to a DS75176 RS-485 transceiver. 
PIN SIGNAL AT91SAM7S
--- ------ ---------
 1   RO      RXD0
 2   /RE     RTS
 3   DE      RTS
 4   DI      TXD0
 5   GND     GND
 6   DO      n/c
 7   DO      n/c
 8   +5V     From EXT_VCC via 5V Regulator

The makefile allows you to build just the dlmstp or a simple
server, both for programming into the flash memory of the processor.
The dlmstp is the datalink layer for MS/TP over RS-485.

I used the makefile from the command line on Windows, and 
then used the SAM-BA to send the resulting .bin file to the 
board using a J-Link.  To debug the code from flash, run the 
J-Link GDB Server and then:
> arm-elf-gdb bacnet.elf

I got the crt.s, at91sam7s256.ld, blinker.c, init.c, isr.c, and
timer.c from James P Lynch.  I created the rs485.c based on the 
initialization sequence from serial.c by Keil Electronik.  I 
got the at91sam7s256.h file from Atmel via the Keil website.
I started with the makefile from James P Lynch, but it didn't work
for me.  I then used some ideas from FreeRTOS makefile, and 
created my own makefile from scratch.

Hopefully you find it useful!
