+ Fix a few compiler warnings.
+ Add TickType_t specific critical sections so critical sections are not used when accessing the tick count in cases where the access is atomic (32-bit tick count, 32-bit architecture).
+ Update the RZ IAR project so it targets the RZ RSK rather than custom hardware.
+ Update the RZ ARM/DS-5 project so it targets the RZ RSK rather than custom hardware.
+ Updated RX64M demos to use the new iodefine.h naming.
Cortex-A9 port related:
+ Update IAR, ARM and GCC Cortex-A9 port layers to include a 'task exit error' function which is called if a task attempts to incorrectly exit its implementing function.
+ Moved the instruction which switches into system mode out of the restore context macro, as it is only needed when starting the first task.
Core kernel files related:
+ Ensure there are no references to the mutexes held count when mutexes are excluded from the build.
Helper updates to allow a count of the number of mutexes held to be added.
Updates to the CCS Cortex-R4 implementation necessitated by a change in compiler semantics.
Update PIC32MX and MZ ports to assert if a non ISR safe function is called from an ISR.
Replace LDMFD with POP instructions in IAR and RVDS Cortex-A9 ports.
Replace branch to address with indirect branch and exchange to address in register in the IAR and RVDS Cortex-A9 ports.
Replace #define types with typedefs.
Rename all typedefs to have a _t extension.
Add #defines to automatically convert old FreeRTOS specific types to their new names (with the _t).
Update the Cortex-A9 port to include asserts if an ISR safe FreeRTOS function is called from an interrupt that has a higher logical priority than configMAX_SYSCALL_INTERRUPT_PRIORITY (or whatever the CA9 equivalent is called), and also assert if the binary point is not set correctly.
