* fix overallocation in WC_DECLARE_ARRAY() macro in the !WOLFSSL_SMALL_STACK path. * rename WC_INIT_ARRAY() to WC_ALLOC_ARRAY() for clarity (it doesn't initialize any memory). * rename WC_DECLARE_ARRAY_DYNAMIC_DEC(), WC_DECLARE_ARRAY_DYNAMIC_EXE(), and WC_FREE_ARRAY_DYNAMIC() to WC_DECLARE_HEAP_ARRAY(), WC_ALLOC_HEAP_ARRAY(), and WC_FREE_HEAP_ARRAY(), respectively, also for clarity, and refactor out the duplicate definitions. * add WC_ALLOC_VAR(), and move the XMALLOC() in smallstack WC_DECLARE_VAR() into it. smallstack WC_DECLARE_VAR() now initializes the pointer to NULL, like smallstack WC_DECLARE_ARRAY(), assuring all pointers are valid upon shortcircuit to cleanup for a failed allocation (see WC_ALLOC_DO_ON_FAILURE below). * add a new hook "WC_ALLOC_DO_ON_FAILURE" in WC_ALLOC_VAR(), WC_ALLOC_ARRAY(), and WC_DECLARE_ARRAY_DYNAMIC_EXE(), which is invoked when an allocation fails. by default the hook is defined to WC_DO_NOTHING. * add basic safety to WC_*_HEAP_ARRAY() by recording/detecting allocation state via idx##VAR_NAME. * add macros WC_ARRAY_OK() and WC_HEAP_ARRAY_OK() to test if allocation succeeded. * add macros WC_CALLOC_ARRAY() and WC_CALLOC_HEAP_ARRAY() which zero the objects. * add macro WC_CALLOC_VAR() which zeros the object. ED448: smallstack refactor of ge448_scalarmult_base(). src/tls.c tests/api.c wolfcrypt/test/test.c: update WC_DECLARE_VAR()s with now-required matching WC_ALLOC_VAR()s. wolfcrypt/benchmark/benchmark.c: * no functional changes in default error-free behavior. * add definition of WC_ALLOC_DO_ON_FAILURE() that prints error message, sets ret, and does goto exit. * add BENCH_NTIMES and BENCH_AGREETIMES overrideeable macros, to allow fast sanitizer runs and slow high-precision runs. * smallstack refactor of all declarations of stack arrays of the form foo[BENCH_MAX_PENDING], using WC_DECLARE_ARRAY() (35 in all). * additional smallstack refactors, using WC_DECLARE_VAR(), for bench_aesxts(), bench_ed448KeyGen(), bench_eccsi*(), and bench_sakke*(). * fixes for various unhandled error conditions around malloc failures. wolfcrypt/test/test.c: opportunistically constify several (42) static constants, moving them to the readonly data segment. linuxkm/Makefile: if ENABLED_LINUXKM_BENCHMARKS, add wolfcrypt/benchmark/benchmark.o to WOLFSSL_OBJ_FILES. linuxkm/Kbuild: enable FPU for benchmark.o, and remove enablement for module_hooks.o. linuxkm/module_hooks.c: remove inline include of benchmark.c.
