Fix Bug#21704 Renaming column does not update FK definition

renamed and denying the ALTER in this case.
The patch was originally developed by Davi Arnaut <Davi.Arnaut@Sun.COM>:
http://lists.mysql.com/commits/77714
and was later adjusted to conform to InnoDB coding style by me (Vasil),
I also added some more comments and moved the bug specific mysql-test to

where doxygenify.pl is

Verified the consistency as follows:
(0) not too many /* in: */ or /* out: */ comments left in the code:
grep -l '/\*\s*\(in\|out\)[,:/]' */*[ch]
(1) no difference when ignoring blank lines, after stripping all

trx_sys_file_format_max_upgrade(): Rename from
trx_sys_file_format_max_update(). Improve the documentation. Add a
const qualifier to the parameter "name". Replace the parameter
"flags" with "format_id", because this function should deal with file
format identifiers, not with table flags.
trx_sys_file_format_max_write(), trx_sys_file_format_max_set(): Add a
const qualifier to the parameter "name".
ha_innodb.cc: Correct the spelling in some comments: "side effect".
Remove redundant prototypes for some static callback functions.
innodb_file_format_name_update(), innodb_file_format_check_update():
Correct the function signature. Use appropriate pointer type conversions.
MYSQL_SYSVAR_STR(file_format), MYSQL_SYSVAR_STR(file_format_check):
Remove the type conversions from the callback function pointers. When
the function signatures match, no type conversion is needed. The type
conversions would only prevent compilation warnings for any mismatch.
Approved by Sunny in rb://25.
buf_block_dbg_add_level(block, level): Define as an empty macro when
UNIV_SYNC_DEBUG is not defined. Remove #ifdef UNIV_SYNC_DEBUG around
all invocations.
This is to fix an unintended side effect of file_format_check changes.
We were reading the trx system page (TRX_SYS_PAGE_NO) before starting
recovery and that resulted in redo logs not being applied to the page.
The fix is to force a reread by calling buf_pool_invalidate().
This, however, made necessary that any writes to page are deferred to
until after the redo log application.

Implement the system tablespace tagging described on the wiki:
https://svn.innodb.com/innobase/InnoDB_version_and_feature_compatibility
A brief description of the changes:
* The file format tag will be saved in the trx system page, starting at
(UNIV_PAGE_SIZE - 16) for 8 bytes.
* The configuration parameter innodb_file_format_check is introduced.
This variable can be set to on/off and any of the supported file
formats in the configuration file, but can only be set to any of
the supported file formats during runtime. The default is on.
* During table create/open, check the current file format against
the max in file_format_max. If the current file format is newer,
update file_format_max and tag the system tablespace with the
newer one in a normal mtr.
* During startup, write the tag to the error log and check it against
DICT_TF_FORMAT_MAX. Refuse to start with error, if
-- DICT_TF_FORMAT_MAX < the tag, and
-- innodb_file_format_check is ON
Print out a warning , if
-- DICT_TF_FORMAT_MAX < the tag, but
-- innodb_file_format_check is off
* The system tablespace tag is re-settable using:
set innodb_file_format_check = <file_format>

lexyy.c, make_flex.sh: Declare yylex as UNIV_INTERN, not static. It is
referenced from pars0grm.c.
Actually, according to
nm .libs/ha_innodb.so|grep -w '[ABCE-TVXYZ]'
the following symbols are still global:
* The vtable for class ha_innodb
* pars0grm.c: The function yyparse() and the variables yychar, yylval, yynerrs
The required changes to the Bison-generated file pars0grm.c will be addressed
in a separate commit, which will add a script similar to make_flex.sh.
The class ha_innodb is renamed from class ha_innobase by a #define. Thus,
there will be no clash with the builtin InnoDB. However, there will be some
overhead for invoking virtual methods of class ha_innodb. Ideas for making
the vtable hidden are welcome. -fvisibility=hidden is not available in GCC 3.
