Update to RandomX v1.1.3, simplify

We don't need to detect if the cache has changed, just always
call to set it on the VM. The call will be a no-op if the cache
hasn't changed.

wallet: add --extra-entropy command line flag

It lets the user add custom entropy to the PRNG.
It does this by hashing the new data and xoring the resulting
hash with the PRNG state.

Minimalistic JIT code generator for random math sequence in CryptonightR.
Usage:
- Allocate writable and executable memory
- Call v4_generate_JIT_code with "buf" pointed to memory allocated on the previous step
- Call the generated code instead of "v4_random_math(code, r)", omit the "code" parameter

discontinue use of alloca
...
NetBSD emits:
warning: Warning: reference to the libc supplied alloca(3); this most likely will not work. Please use the compiler provided version of alloca(3), by supplying the appropriate compiler flags (e.g. not -std=c89).
and man 3 alloca says:
Normally, gcc(1) translates calls to alloca() with inlined code. This is not done when either the -ansi, -std=c89, -std=c99, or the
-std=c11 option is given and the header <alloca.h> is not included. Otherwise, (without an -ansi or -std=c* option) the glibc version of
<stdlib.h> includes <alloca.h> and that contains the lines:
#ifdef __GNUC__
#define alloca(size) __builtin_alloca (size)
#endif
It looks like alloca is a bad idea in modern C/C++, so we use
VLAs for C and std::vector for C++.
