Revert "Remove coroutines (#874)" (#1019)

Browse source 
* Revert "Remove coroutines (#874)"

This reverts commit 569c78fd8c.

* Update freertos Kernel submodule to latest head

* Remove temporary files

* Fix MingW demos and spell check

* Fix manifest version; fix headers

* Add ignore files and paths to core-checker.py

* Fix copyright in remaining files

* Fix PR check build failure

1. Remove defining `inline` in Makefile. This was causing build
   warnings.
2. Ensure that the linker removed unused functions from various
   compilation units.
3. Update the linker script so that all the functions are correctly
   placed in FLASH section.

/*
* This demo application creates seven co-routines and one task (two including
* the idle task). The co-routines execute as part of the idle task hook.
*
* Five of the created co-routines are the standard 'co-routine flash'
* co-routines contained within the Demo/Common/Minimal/crflash.c file and
* documented on the FreeRTOS.org WEB site.
*
* The 'LCD Task' rotates a string on the LCD, delaying between each character
* as necessitated by the slow interface, and delaying between each string just
* long enough to enable the text to be read.
*
* The sixth co-routine controls the transmission of a string to UART 0. The
* co-routine periodically sends the first character of the string to the UART,
* with the UART's TxEnd interrupt being used to transmit the remaining
* characters. The UART's RxEnd interrupt receives the characters and places
* them on a queue to be processed by the seventh and final co-routine. An
* error is latched should an unexpected character be received, or any
* character be received out of sequence.
*
* A loopback connector is required to ensure that each character transmitted
* on the UART is also received on the same UART. For test purposes the UART
* FIFO's are not utalised in order to maximise the interrupt overhead. Also
* a pseudo random interval is used between the start of each transmission in
* order that the resultant interrupts are more randomly distributed and
* therefore more likely to highlight any problems.
*
* The flash co-routines control LED's zero to four. LED five is toggled each
* time the string is transmitted on the UART. LED six is toggled each time
* the string is CORRECTLY received on the UART. LED seven is latched on should
* an error be detected in any task or co-routine.
*
* In addition the idle task makes repetitive calls to
* prvSetAndCheckRegisters(). This simply loads the general purpose registers
* with a known value, then checks each register to ensure the held value is
* still correct. As a low priority task this checking routine is likely to
* get repeatedly swapped in and out. A register being found to contain an
* incorrect value is therefore indicative of an error in the task switching
* mechansim.

* The sixth co-routine and final task control the transmission and reception

* used to transmit the remaining characters. The UART's RxEnd interrupt
* receives the characters and places them on a queue to be processed by the
* 'COMs Rx' task. An error is latched should an unexpected character be
* received, or any character be received out of sequence.
*
* A loopback connector is required to ensure that each character transmitted

/*
* This is a mini co-routine demo for the Rowley CrossFire LM3S102 development
* board. It makes use of the boards tri-colour LED and analogue input.
*
* Four co-routines are created - an 'I2C' co-routine and three 'flash'
* co-routines.
*
* The I2C co-routine triggers an ADC conversion then blocks on a queue to
* wait for the conversion result - which it receives on the queue directly
* from the I2C interrupt service routine. The conversion result is then
* scalled to a delay period. The I2C interrupt then wakes each of the
* flash co-routines before itself delaying for the calculated period and
* then repeating the whole process.
*
* When woken by the I2C co-routine the flash co-routines each block for
* a given period, illuminate an LED for a fixed period, then go back to
* sleep to wait for the next cycle. The uxIndex parameter of the flash
* co-routines is used to ensure that each flashes a different LED, and that
* the delay periods are such that the LED's get flashed in sequence.
