Merge a change from MySQL (this fixes the failing innodb-replace test):

message:
Bug#31210: INSERT DELAYED crashes server when used on partitioned tables
Problem was an unclear error message since it could suggest that
MyISAM did not support INSERT DELAYED.
Changed the error message to say that DELAYED is not supported by the
table, instead of the table's storage engine.
The confusion is that a partitioned table is in somewhat sense using
the partitioning storage engine, which in turn uses the ordinary
storage engine. By saying that the table does not support DELAYED we
do not give any extra informantion about the storage engine or if it
is partitioned.

symbols. Use it for all definitions of non-static variables and functions.
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.
UNIV_PAGE_SIZE than the default 16384.
MEM_BLOCK_STANDARD_SIZE: Cap to MEM_MAX_ALLOC_IN_BUF when UNIV_PAGE_SIZE
is less than 16384.
ha_create_func(): Invoke mem_heap_create_in_btr_search() with
ut_min(4096, MEM_MAX_ALLOC_IN_BUF) instead of 4096. The memory
will be allocated from the buffer pool, and with UNIV_PAGE_SIZE
defined to 4096, there would not be any space for the mem_heap
data structure overhead.
buf0buf.ic: Remove the extern declaration of buf_dbg_counter.
It was declared static in buf0buf.c in r1025.
ha0ha.c: #include "btr0sea.h" #ifdef UNIV_SYNC_DEBUG. Assertions on
btr_search_latch were added in r1041.
hash index, because it might occupy the chunk we would like to free.
TODO: In btr_search_check_free_space_in_heap(), release the block if
btr_search_latch is not immediately available.
buf_pool_shrink(): Split from buf_pool_resize().
btr_search_disabled: New variable, similar to srv_use_adaptive_hash_indexes
that was removed earlier.
btr_search_disable(): New function: disable and purge the adaptive hash index.
btr_search_enable(): New function: enable the adaptive hash index.
ha_clear(): New function: Empty a hash table and free the memory heaps.
when assigning node->data.
ha_delete(), ha_search_and_delete_if_found(), ha_remove_all_nodes_to_page():
Remove the parameter buf_block_t* block, now that it is stored within the
hash data structure in debug builds.
an assertion failure in debug builds when a context switch occurred in
buf_LRU_search_and_free_block() before the call to
btr_search_drop_page_hash_index() managed to acquire the mutexes again.
ha_node_t: Add the field buf_block_t* block.
ha_search_and_update_if_found(): Rename to ha_search_and_update_if_found_func()
with added buf_block_t* parameter in debug builds. Define the wrapper macro
ha_search_and_update_if_found() that always takes the buf_block_t* parameter.
ha_insert_for_fold(): Rename to ha_insert_for_fold_func()
with added buf_block_t* parameter in debug builds. Define the wrapper macro
ha_insert_for_fold() that always takes the buf_block_t* parameter.
Instead, get buf_block_t* as a parameter.
Without this patch, buf_page_hash_get() would return NULL in
buf_block_align(). The function buf_LRU_search_and_free_block()
invokes buf_LRU_block_remove_hashed_page(), which removes the
hash mapping needed by buf_page_hash_get().
rec_get_nth_field_offs_old(): Split from rec_get_nth_field_old().
rec_get_nth_field_old(): Reimplement as a constness-preserving macro.
dict_drop_index_tree(), dict_truncate_index_tree(): Note that rec is
an in/out parameter, as the B-tree root page number will be updated.

Enclose hash_table_t::adaptive and buf_block_t::n_pointers in

btr_search_drop_page_hash_index(): Enclose the corruption check
(which depends on buf_block_t::n_pointers) in #ifdef UNIV_DEBUG.
