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>

in *.h files, so that the function signatures in the *.h and *.c files fully
match each other.
ut_dulint_sort(): Add a UNIV_INTERN qualifier also to the function definition.

include/innodb_redefine.h: Remove.
include/sync0sync.h: Remove the definition of mutex_free that was added
because of innodb_redefine.h.
include/univ.i: Remove references to innodb_redefine.h. Explain why
the C++ classes need to be renamed.
scripts/build-plugin.sh: Build InnoDB only once. The file
innodb_redefine.h is no longer needed.
defined in innodb_redefine.h must not be undefined. After this change,
innodb_redefine.h will define mutex0_free instead of mutex_free, and
everything is fine.

for design notes.
Things that need to be resolved before this goes live:
* MySQL must add thd_get_thread_id() function to their code
http://bugs.mysql.com/30930
* Allocate memory from mem_heap instead of using mem_alloc()
* Copy table name and index name into the cache because they may be
freed later which will result in referencing freed memory

now that all of InnoDB code is built from a single Makefile and it should
not be possible to build the modules with mutually incompatible options.
#define INSIDE_HA_INNOBASE_CC: Remove.
srv_sizeof_trx_t_in_ha_innodb_cc: Remove.
dict_table_get_low_noninlined(): Remove. This function was unused.
Remove all _noninline functions. Remove the _noninline suffix from
all function calls in ha_innodb.cc.
