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.

c393e824d6 CryptonightR_JIT: fix return value on error 
The value was positive rather than zero, but the caller only
checks for negative errors

ensure no NULL is passed to memcpy 
NULL is valid when size is 0, but memcpy uses nonnull attributes,
so let's not poke the bear

CNv4 JIT compiler for x86-64 and tests 
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++.

c4fbfd786a Small function declaration cleanup in slow-hash.c 
- These functions are declared twice in slow-hash.c. Remove one of the copies.
- The declarations have the wrong return type, should be void, not int.

Function definitions here: 1e74586ee9/src/crypto/aesb.c (L151-L180)
Test plan: make release-test
