* Faster cache initialization with SSSE3/AVX2
* Automatic detection of CPU capabilities in RandomX
* Fixed a possible out-of-bounds access in superscalar program generator
* Use MONERO_RANDOMX_UMASK to manually disable RandomX flags in monerod

Fix for miners on reorg 
Make sure dataset gets re-init'd if a reorg changes the epoch

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.

ensure no NULL is passed to memcpy

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++.
