Add TRY_ENTRY_CRITICAL() API to all for timeouts when entering critical sections. The following port API were added: - portTRY_ENTER_CRITICAL() - portTRY_ENTER_CRITICAL_ISR() - portTRY_ENTER_CRITICAL_SAFE() Deprecated legacy spinlock API in favor of spinlock.h. The following API were deprecated: - vPortCPUInitializeMutex() - vPortCPUAcquireMutex() - vPortCPUAcquireMutexTimeout() - vPortCPUReleaseMutex() Other Changes: - Added portMUX_INITIALIZE() to replace vPortCPUInitializeMutex() - The assembly of the critical section functions ends up being about 50 instructions longer, thus the spinlock test pass threshold had to be increased to account for the extra runtime.
