Subject: [PATCH] Add recomp_printf implementation and related exports

Introduces recomp_printf as a variadic print function using a custom _Printf handler. Adds misc_funcs.h for function declarations, print.c for the implementation, and updates syms.ld with new symbol exports. Also updates patches.h to declare recomp_printf.
