MDEV-10547: Test multi_update_innodb fails with InnoDB 5.7
The failure happened because 5.7 has changed the signature of
the bool handler::primary_key_is_clustered() const
virtual function ("const" was added). InnoDB was using the old
signature which caused the function not to be used.
MDEV-10550: Parallel replication lock waits/deadlock handling does not work with InnoDB 5.7
Fixed mutexing problem on lock_trx_handle_wait. Note that
rpl_parallel and rpl_optimistic_parallel tests still
fail.
MDEV-10156 : Group commit tests fail on 10.2 InnoDB (branch bb-10.2-jan)
Reason: incorrect merge
MDEV-10550: Parallel replication can't sync with master in InnoDB 5.7 (branch bb-10.2-jan)

This is never hit in practice, because the wrapper code catches it,
but fix the zero length exit to restore all the non volatile registers.

Move crc32-vpmsum to extra.
Compile static crc32-vpmsum instead of adding sources directly.
Make use of crc32-vpmsum via my_checksum().
Based on contribution by Daniel Black.
`--help` is a perfectly valid parameter and both `mysqladmin` and
`mysql_waitpid` should exit with success (zero errror code).

DESCRIPTION
===========
Buffer overflow is reported in a lot of code sections
spanning across server, client programs, Regex libraries
etc. If not handled appropriately, they can cause abnormal
behaviour.
ANALYSIS
========
The reported casea are the ones which are likely to result
in SEGFAULT, MEMORY LEAK etc.
FIX
===
- sprintf() has been replaced by my_snprintf() to avoid
buffer overflow.
- my_free() is done after checking if the pointer isn't
NULL already and setting it to NULL thereafter at few
places.
- Buffer is ensured to be large enough to hold the data.
- 'unsigned int' (aka 'uint') is replaced with 'size_t'
to avoid wraparound.
- Memory is freed (if not done so) after its alloced and
used.
- Inserted assert() for size check in InnoDb memcached
code (from 5.6 onwards)
- Other minor changes
(cherry picked from commit 3487e20959c940cbd24429afa795ebfc8a01e94f)
Don't read from socket in yassl in SSL_pending().
Just return size of the buffered processed data.
This is what OpenSSL is documented to do too:
SSL_pending() returns the number of bytes which have been processed,
buffered and are available inside ssl for immediate read.
This is done by splitting variables.errmsg and locale.errmsg to
variables.errmsg_extra and locale.errmsg_extra
The ER() macros in unireg.h now looks more complex than before, but this
isn't critical as most usage of them are with constants and the compiler
will remove most of the test code.
one leading zeros for the key agreement instead of
potentially any number.
There is about 1 in 50,000 connections to fail
when using DHE cipher suites. The second problem was the
case where a server would send a public value shorter than
the prime value, causing about 1 in 128 client connections
to fail, and also caused the yaSSL client to read off the
end of memory.
All client side DHE cipher suite users should update.
Note: The patch is received from YaSSL people
- Make accelerated checksum available to InnoDB and XtraDB.
- Fall back to slice-by-eight if not available. The mode used is printed on startup.
- Will only build on POWER systems at the moment until CMakeLists are modified
to only add the crc32_power8/ files when building on POWER.

This includes fixing all utilities to not have any memory leaks,
as safemalloc warnings stopped tests from passing on MacOSX.
- Ensure that all clients takes character-set-dir, as the
libmysqlclient library will use it.
- mysql-test-run now passes character-set-dir to all external clients.
- Changed dynstr_free() so that it can be called twice (made freeing code easier)
- Changed rpl_global_gtid_slave_state to be allocated dynamicly as it
includes a mutex that needs to be initizlied/destroyed before my_end() is called.
- Removed rpl_slave_state::init() and rpl_slave_stage::deinit() as
their job are better handling by constructor and delete.
- Print alias instead of table_name in check_duplicate_key as
table_name may have been converted to lower case.
Other things:
- Fixed a case in time_to_datetime_with_warn() where we where
using && instead of & in tests
