In early development of delete buffering, we did allow B-tree pages
to become empty as a result of buffered deletes. That caused fundamental
problems. The fix was to refuse buffering purge operations unless
the page can be guaranteed to be nonempty. Remove an attempt to
cope with empty pages when merging inserts.
Remove non applicable licensing files
storage/innobase/COPYING is in the MySQL top level directory and
storage/innobase/COPYING.Sun_Microsystems is not applicable anymore
now that Oracle and Sun are one company.
On Solaris with version 3.4.6, the ha_example.so shared library is built
with DTrace and the server is built without DTrace support. This occurs
because dtrace.cmake disables DTrace support for 3.4.6, but still set
HAVE_DTRACE, which causes probes_mysql.h to include probes_mysql_dtrace.h
instead of probes_mysql_nodtrace.h.
This patch fixes this by not setting HAVE_DTRACE on Solaris for GCC 3.4.6.
create data dir correctly in initial_database target on Windows
handle case where INSTALL_MYSQLTESTDIR is empty (e.g someone does not want
to install tests)
thread-specific variables weren't set when we load error message files.

Bug#53251 mysql_library_init fails on second execution with embedded library
we need to call my_thread_init() once more. Normally it's called at the my_init()
stage but that doesn't happen on the second my_init() call.
sql/derror.cc
Bug#53251 mysql_library_init fails on second execution with embedded library
use default errors for the embedded server.
sql/mysqld.cc
Bug#53251 mysql_library_init fails on second execution with embedded library
unregister server errors in clean_up(). Without it the error list contains
that on the second mysql_server_init() which is not good.
sql/set_var.cc
Bug#53251 mysql_library_init fails on second execution with embedded library
sys_var::cleanup() call instead of the destructor
sql/set_var.h
Bug#53251 mysql_library_init fails on second execution with embedded library
sys_var::cleanup() introduced instead of the destructor

Bug#53251 mysql_library_init fails on second execution with embedded library
Sys_var_charptr::cleanup() implemented
When in embedded-serve mode, mysqltest tried to run '--send' commands in the separate thread.
That upsets some engines (InnoDB particularly) as the transaction has to be executed in the same
thread completely. So i implemented some different approach. So we create one separate thread for
each connection and execute all the queries of this connection inside it. Looks even simpler than it was
for me.

Bug#54861 Additional connections not handled properly in mtr --embedded
Now the connection has one running connection_thread() attached. And sends all the
query and read-result requests to it.
made libmysqld/Makefile.am to have same licence as libmysqld/CMakeLists.txt
per-file comments:
libmysqld/Makefile.am
Bug#54906 Inconsistent license of libmysqld
Added GPL license header instead of Library GPL.
Problem:
- ORDER BY for utf8mb4_bin, utf16_bin and utf32_bin returned
results in a wrong order, because old functions
(supporting only BMP range) were used to handle these collations.
- Additionally, utf16_bin did not sort supplementary characters
between U+D700 and U+E000, as WL#1213 specification specified.
"Access compatibility" syntax
The "wild" "DELETE FROM table_name.* ... USING ..." syntax
for multi-table DELETE statements is documented but it was
lost in the fix for the bug 30234.
The table_ident_opt_wild parser rule has been added
to restore the lost syntax.
