This will allow to check ABI for C++ plugins defined in include/mysql/plugin.h
e.g. like this:
struct st_mysql_xxx
{
int interface_version;
const class XXX *xxx;
};
Discussed with Serg.
The gcc version in CentOS 7 is 4.8.2 (released in Mar 2013).
But Arm added the support for 'arm_acle.h' in gcc 5.1 (released in Jun 2014).
And there are also some bugs in Arm gcc 4.8.
The patch is to detect GCC(greater than 5.1) version for Arm crc32c.

If it is not enabled, build wsrep as static "stub" library from wsrep_dummy.cc
´
Allow static plugins to export symbols (on Unix)
wsrep_info relies on wsrep defined symbols (e.g LOCK_wsrep_config_state)
exported from mysqld
`cmake . -DWITH_EXTRA_CHARSETS=complex` did not compile.
Fixing forgotten "utf8" to "utf8mb3" in definitions of
CHARSET and CHARSETS_AVAILABLE in cmake/character_sets.cmake
Improve previous patch so we do not depend on (tiny) compiler-version
dependent libraries, i.e vcruntime140.dll, and msvcp140.dll
The remaining dependency is Universal CRT, is part of Win10+ OS,
and should already be installed by Windows update on most downlevel
systems.
post-merge fixes:
* .gitignore
* don't put the keyword COMPONENT into ${COMP} anymore
* don't alias mytop, but do alias mysql_client_test
* don't symlink manpages, use troff aliasing technique instead
(symlinked manpages break rpm and out-of-source bintar builds)
* move debian to use troff aliased manpages, fix typos in debian files,
put aliases in the correct packages, add more aliases to match
rpm/bintar packaging

Apparently, WolfSSL wants to have *exactly* the same defines for
the user of the library as the was when building library itself.
A lot of #defines have an impact on ABI (structure sizes, alignment etc)
In Wolfcrypt, output length after CTR encryption is not the same
as input length. This is different from openssl and this makes unit test
aes-t fail.
So disable CTR for now.
ARMv8 (AArch64) CPUs implement the CRC32 extension which is implemented by inline assembly ,
so they can also benefit from hardware acceleration in IO-intensive workloads.
The patch optimizes crc32c calculate with the armv8 crypto instruction(Intrinsics) when available
rather than original linear crc instructions.

- Add new submodule for WolfSSL
- Build and use wolfssl and wolfcrypt instead of yassl/taocrypt
- Use HAVE_WOLFSSL instead of HAVE_YASSL
- Increase MY_AES_CTX_SIZE, to avoid compile time asserts in my_crypt.cc
(sizeof(EVP_CIPHER_CTX) is larger on WolfSSL)
