* Patch eap.o memory leak WiFi Enterprise option can leak up to 3 allocations per connect/disconnect cycle: anonymous Identity, password, and some unidentified allocation. This solution patches eap.o from libwpa2 to call a special 2 part wrapper instead of vPortFree for cleanup. Corrected typos and adjusted tabs in script. Added script eval_fix_sdks.sh to aid in evaluating similarity between patch sections of .o files being patched across different SDKs. * Add some dev debug code and improve comments * Patch eap.o memory leak WiFi Enterprise option can leak up to 3 allocations per connect/disconnect cycle: anonymous Identity, password, and some unidentified allocation.
