This problem surfaced when running new test innodb_bug40360.test. Both
tx_isolation_names and binlog_format_names are name arrays, and
should be defined as wdl_tx_isolation_names and wdl_binlog_format_names,
not *wdl_tx_isolation_names and *wdl_binlog_format_names.
Another array variable is all_charsets, which is already correctly
defined.

Revert our temporary fix for "Bug#40360 Binlog related errors with binlog off"
(r2935, r2936) and deploy MySQL's one, but put the function
mysql_bin_log_is_engaged() inside mysql_addons.cc instead of in mysql's log.cc
and use a different name for it so there is no collision when MySQL adds this
function in log.cc.
[note from the future: the windows part of this patch went into r2947]

Followup to r2935: add the Windows Delay Loader stuff for the MySQL
variable that we are accessing. If someday we have another solution for
Bug#40360 Binlog related errors with binlog off
then this should also be reverted.
on Windows, which includes:
* Load mysqld.map and insert all symbol/address pairs into hash for
quick access
* Resolves all external data variables. The delayloading mechanism
in MSVC does not support automatic imports of data variables.
A workaround is to explicitly handle the data import using the delay
loader during the initialization of the plugin.
* Resolves all external functions during run-time, by implementing
the delayed loading helper function delayLoadHelper2, which is
called by run-time as well as HrLoadAllImportsForDll.
The delay loader reuses the hash implementation in InnoDB. The normal
hash_create (in hash0hash.c) creates hash tables in buffer pool. But
the delay loader is invoked before the engine is initialized, and
buffer pools are not ready yet. Instead, the delay loader has its own
implementation of hash_create() and hash_table_free(), called
wdl_hash_create() and wdl_hash_table_free().
This patch should be used with other two patches in order to build
a dynamically linked plugin on Windows:
* patch for tmpfile functions (r2886)
* patch for "build" files (to be committed)
The list of file changed:
handler/handler0vars.h: new file, defines a list of external data
variables (no external functions).
handler/win_delay_loader.cc: new file, the implementation of the delay
loader for Windows plugin.
handler/ha_innodb.cc: add a header file, and changes for copying the
system variables.
handler/handler0alter.cc: add a header file
handler/i_s.cc: add a header file
