Sergei Golubchik 3d2d060b62 fix gcc 8 compiler warnings
There were two newly enabled warnings:
1. cast for a function pointers. Affected sql_analyse.h, mi_write.c
   and ma_write.cc, mf_iocache-t.cc, mysqlbinlog.cc, encryption.cc, etc

2. memcpy/memset of nontrivial structures. Fixed as:
* the warning disabled for InnoDB
* TABLE, TABLE_SHARE, and TABLE_LIST got a new method reset() which
  does the bzero(), which is safe for these classes, but any other
  bzero() will still cause a warning
* Table_scope_and_contents_source_st uses `TABLE_LIST *` (trivial)
  instead of `SQL_I_List<TABLE_LIST>` (not trivial) so it's safe to
  bzero now.
* added casts in debug_sync.cc and sql_select.cc (for JOIN)
* move assignment method for MDL_request instead of memcpy()
* PARTIAL_INDEX_INTERSECT_INFO::init() instead of bzero()
* remove constructor from READ_RECORD() to make it trivial
* replace some memcpy() with c++ copy assignments

Unit tests directory structure
------------------------------

This is the current structure of the unit tests.  More directories
will be added over time.

mytap                 Source for the MyTAP library
mysys                 Tests for mysys components
  bitmap-t.c          Unit test for MY_BITMAP
  base64-t.c          Unit test for base64 encoding functions
examples              Example unit tests.
  core-t.c            Example of raising a signal in the middle of the test
		      THIS TEST WILL STOP ALL FURTHER TESTING!
  simple-t.c          Example of a standard TAP unit test
  skip-t.c            Example where some test points are skipped
  skip_all-t.c        Example of a test where the entire test is skipped
  todo-t.c            Example where test contain test points that are TODO
  no_plan-t.c         Example of a test with no plan (avoid this)


Executing unit tests
--------------------

To make and execute all unit tests in the directory:

   make test

Observe that the tests in the examples/ directory are just various
examples of tests and are not expected to pass.


Adding unit tests
-----------------

Add a file with a name of the format "foo-t.c" to the appropriate
directory and add the following to the Makefile.am in that directory
(where ... denotes stuff already there):

  noinst_PROGRAMS = ... foo-t

Note, it's important to have "-t" at the end of the filename, otherwise the
test won't be executed by 'make test' !


Documentation
-------------

The generated documentation is temporarily placed at:

      http://www.kindahl.net/mytap/doc/

I will move it to a better place once I figure out where and how.
