Setting configENABLE_HEAP_PROTECTOR to 1 obfuscates heap block pointers by XORing them with an application supplied canary value. This obfuscation helps to catch heap corruption should a heap buffer overflow occur. This PR also adds heap bounds checking to heap_4 and heap_5. This PR also adds some additional integer underflow checks.
Each real time kernel port consists of three files that contain the core kernel components and are common to every port, and one or more files that are specific to a particular microcontroller and/or compiler. + The FreeRTOS/Source/Portable/MemMang directory contains the five sample memory allocators as described on the https://www.FreeRTOS.org WEB site. + The other directories each contain files specific to a particular microcontroller or compiler, where the directory name denotes the compiler specific files the directory contains. For example, if you are interested in the [compiler] port for the [architecture] microcontroller, then the port specific files are contained in FreeRTOS/Source/Portable/[compiler]/[architecture] directory. If this is the only port you are interested in then all the other directories can be ignored.
