Subject: [PATCH] - change OSAL_TASK_FUNCTION to have void* parameter (to be
 consistent with most popular RTOS) - add new error enum
 TUSB_ERROR_OSAL_TASK_CREATE_FAILED - move usbh_enumeration_task prototype to
 usbh.h - change OSAL_SUBTASK_INVOKED_AND_WAIT behavior, will not "return" in
 calling task when subtask got error status. calling task need to do that
 after the call - osal_queue_receive signature from uint32_t* to void*

- implement osal_freertos.h for FreeRTOS 7.3 --> able to compile & build host_freertos
+ OSAL_TASK_FUNCTION
+ turn on FPU for M4 in both host_os_none & host_freertos (freertos requires FPU to be on to compile)
+ osal_task_create
+ OSAL_SUBTASK_INVOKED_AND_WAIT
+ SUBTASK_ASSERT
+ osal_semaphore_reset
+ osal_queue_flush
+ adding heap_1.c for memory management
