In FreeRTOS_Plus_TCP_Echo_Posix/console.c: - Add missing xSemaphoreGive() call in console_print() to prevent mutex starvation after vprintf completes - Fix uncrustify formatting: indent preprocessor directives (#if/#else/#endif), add space between #if and condition, remove space in empty xSemaphoreCreateMutex()
