Add the errno definitions used by FreeRTOS+TCP and FreeRTOS+FAT into FreeRTOS's projdefs.h.
Remove redundant global definition vPortInstallFreeRTOSVectorTable from the GCC ARM_CA9 portASM.S file.
Ensure correct sequence of start up sequence when the Windows port is used on multi-core Windows machines by starting one thread in the suspended state.
Move initialisation of xNextTaskUnblockTime to the function that starts the scheduler, rather than from where the variable is declared - this fixes a compiler warning in newer IAR compilers.
Fix "elif (SELECTED_PORT == PORT_MICROCHIP_PIC32MX || PORT_MICROCHIP_PIC32MZ)" in the FreeRTOS+Trace trcHardwarePort.h header file.
