branches/zip: implement the delayloading of externals for the plugin
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.

branches/5.1: dtype_get_sql_null_size(): return the correct storage
size of a SQL NULL column. (Bug #40369)
When MySQL Bug #20877 was fixed in r834, this function was
accidentally modified to return 0 or 1. Apparently, the only impact of
this bug is that fixed-length columns cannot be updated in-place from
or to SQL NULL, even in ROW_FORMAT=REDUNDANT. After this fix,
fixed-length columns in ROW_FORMAT=REDUNDANT will have a constant
storage size as they should, no matter if NULL or non-NULL. The bug
caused fixed-length NULL columns to occupy 1 byte.

Fix "Bug#40360 Binlog related errors with binlog off" in InnoDB code in order
to have a Bug#40360-free InnoDB Plugin 1.0.2.
The fix does check whether binary logging is enabled in MySQL by accessing the
opt_bin_log global variable that is defined in sql/mysqld.cc.
In case MySQL does develop another solution to this via Bug#40360 then we can
revert this patch (except the mysql-tests).
The windows-plugin part of this fix will be committed as a separate commit to
ease eventual merge into branches/5.1 [note from the future: the separate

ha_innobase::final_drop_index(): Lock the user table within prebuilt->trx.
Active transactions must not switch table or index definitions on the fly,

* copied indexes do not carry any history or locking information;
that is, rollbacks, read views, and record locking would be broken

loss of data, and corruption
Instead of trying to track down if the table was changed during a transaction,
acquire appropriate locks that protect the creation and dropping of indexes.
innodb-index.test: Test the locking of CREATE INDEX and DROP INDEX. Test
that consistent reads work across dropped indexes.
lock_rec_insert_check_and_lock(): Relax the lock_table_has() assertion.
When inserting a record into an index, the table must be at least IX-locked.
However, when an index is being created, an IS-lock on the table is
sufficient.
row_merge_lock_table(): Add the parameter enum lock_mode mode, which must

trx_undo_mark_as_dict_operation(): Do not write trx->table_id to the

ha_innobase::add_index(): Set the dict_operation mode initially to

creating a temporary table.
page_cur_set_before_first(), page_cur_set_after_last(),
page_cur_position(): Add const qualifiers to buf_block_t and rec.
A better solution would be to define a const_page_cur_t and a

page_rec_get_next_low(): Add const qualifiers.

page_cur_get_page(), page_cur_get_block(), page_cur_get_page_zip(),
page_cur_get_rec(): Define as const-preserving macros.
page_cur_try_search_shortcut(), page_cur_search_with_match():
Add const qualifiers.
buf_page_get_mutex(): Add a const qualifier to buf_page_t*.
rec_get_next_ptr_const(): Const variant of rec_get_next_ptr().
For some reason, GCC 4.2.1 ignores casts (for removing constness)
in calls to inline functions.
page_align(), ut_align_down(): Make the parameter const void*, but still
return a non-const pointer. This is ugly, but these functions cannot be
replaced with a const-preserving macro in a portable way, given that
the pointer argument is not always pointing to bytes.
buf_block_get_page_zip(): Implement as a const-preserving macro.
buf_frame_get_page_zip(), buf_block_align(): Add const qualifiers.
lock_rec_get_prev(): Silence GCC 4.2.1 warnings.
mlog_write_initial_log_record(), mlog_write_initial_log_record_fast(),
mtr_memo_contains(): Add const qualifier to the pointer.
page_header_get_ptr(): Rewrite as page_header_get_offs(), and
implement as a macro that calls this function.
buf_block_hash_get(): New function, similar to buf_page_hash_get().
buf_page_get_block(): Remove the const qualifiers. This is a low-level
function, and the operations on block->mutex are non-const.
buf_page_try_get_func(): Implement with lower-level predicates, somewhat
similar to buf_page_get_known_nowait().
lock_rec_print(): Remove the unused variable zip_size and the
call to fil_space_get_zip_size(). Adapt to buf_page_try_get() returning
a const pointer.
offsets_[] arrays, as suggested by Vasil.
rec_offs_set_n_alloc(): Declare as a public function. Assert that
