While here:

 - split INSTALL_*DIR variables into two sections, first set the major
   variables, then second set the minor ones, using the major where
   appropriate.

 - format the settings for easier parsing (at least with a wide terminal)

A variable declaration was preceded by "DBUG_PRINT()".

sql-common/client.c:
  Thou shalt not declare a variable after an executable statement
  (and "DBUG_PRINT()" is executable).

extracted from a work-in-progress development branch
just for the build of 5.5.3-m3.

The "cmake" way still shows issues in our release build environment.
Block it temporarily, but in a way that can easily be undone.

This change is to be reverted once the problems are solved.

BUILD/choose_configure.sh:
  Easiest way: Preset "HAVE_CMAKE=no"

There are two issues fixed here:

  1. We needed to update the result file, for some of 
     mysqlbinlog_* tests, because now the some padding chars
     are not output anymore.

  2. We needed to change the Field_string::pack so that
     for BINARY types the padding chars are not packed 
     (lengthsp will return full length for these types).

The problem is introduced by WL#4435 "Support OUT-parameters in 
prepared statements".
When a statement that has out parameters was reprepared,
the reprepare request error was ignored, and an
attempt to send out parameters to the client was made.

Since the out parameter list was not initialized in case
of an error, this attempt led to a crash.

Don't try to send out parameters to the client
if an error occurred in statement execution.

sql/sql_prepare.cc:
  Don't try to send out parameters if error.
tests/mysql_client_test.c:
  Re-enable the test case for Bug#49972.

- Fixing crash on attempt to create a fulltext index with an utf8mb4 column
- fixing wrong border width  for supplementary characters in mysql client:

  mysql --default-character-set=utf8mb4 -e "select concat(_utf32 0x20000,'a')"

Split rpl_row_charset into:

  - rpl_row_utf16.
  - rpl_row_utf32.

This way these tests can run independently if server supports
either one of the charsets but not both.

Cleaned up rpl_row_utf32 which had a spurious instruction:
-- let $reset_slave_type_conversions= 0

In BUG#51787 we were using the wrong charset to print out the
data. We were using the field charset for the string that would
hold the information. This caused the assertion, because the
string length was not aligned with UTF32 bytes requirements for
storage.

We fix this by using &my_charset_latin1 in the string object
instead of the field->charset(). As a side-effect, we needed to
extend the show_sql_type interface so that it took the field
charset is now passed as a parameter, so that one is able to
calculate the correct field size.

In BUG#51716 we had issues with Field_string::pack and
Field_string::unpack. When packing, the length was incorrectly
calculated. When unpacking, the padding the string would be
padded with the wrong bytes (a few bytes less than it should).

We fix this by resorting to charset abstractions (functions) that
calculate the correct length when packing and pad correctly the
string when unpacking.

LOCK kills the server.

temporary tables.
Fix a subtle bug in the implementation when we actually
did not remove table share objects from the table cache after 
acquiring exclusive locks.

  Fix a yet another bug in the implementation which 
  did not actually remove the tables from cache after acquiring
