/*
There are two containers holding information about open handler tables.
The first is 'thd->handler_tables'. It is a linked list of TABLE objects.
It is used like 'thd->open_tables' in the table cache. The trick is to
exchange these two lists during open and lock of tables. Thus the normal
table cache code can be used.
The second container is a HASH. It holds objects of the type TABLE_LIST.
Despite its name, no lists of tables but only single structs are hashed
(the 'next' pointer is always NULL). The reason for theis second container
is, that we want handler tables to survive FLUSH TABLE commands. A table
affected by FLUSH TABLE must be closed so that other threads are not
blocked by handler tables still in use. Since we use the normal table cache
functions with 'thd->handler_tables', the closed tables are removed from
this list. Hence we need the original open information for the handler
table in the case that it is used again. This information is handed over
to mysql_ha_open() as a TABLE_LIST. So we store this information in the
second container, where it is not affected by FLUSH TABLE. The second
container is implemented as a hash for performance reasons. Consequently,
we use it not only for re-opening a handler table, but also for the
HANDLER ... READ commands. For this purpose, we store a pointer to the
TABLE structure (in the first container) in the TBALE_LIST object in the
second container. When the table is flushed, the pointer is cleared.

SYNOPSIS
SYNOPSIS
find_table_ptr_by_name
()
mysql_ha_flush
()
thd Thread identifier.
thd Thread identifier.
db Database (schema) name.
tables The list of tables to close. If NULL,
table_name Table name ;-).
close all HANDLER tables [marked as flushed].
is_alias Table name may be an alias name.
mode_flags MYSQL_HA_CLOSE_FINAL finally close the table.
dont_lock Suppresses the normal locking of LOCK_open.
MYSQL_HA_REOPEN_ON_USAGE mark for reopen.
MYSQL_HA_FLUSH_ALL flush all tables, not only
those marked for flush.
DESCRIPTION
DESCRIPTION
Find the table 'db'.'table_name' in the list of HANDLER tables of the
The list of HANDLER tables may be NULL, in which case all HANDLER
thread 'thd'. If the table has been marked by FLUSH TABLE(S), close it,
tables are closed (if MYSQL_HA_FLUSH_ALL) is set.
flag this situation in '*was_flushed' and broadcast a COND_refresh
If 'tables' is NULL and MYSQL_HA_FLUSH_ALL is not set,
condition.
all HANDLER tables marked for flush are closed.
An empty database (schema) name matches all database (schema) names.
Broadcasts a COND_refresh condition, for every table closed.
If the caller did already lock LOCK_open, it must set 'dont_lock'.
The caller must lock LOCK_open.
IMPLEMENTATION
NOTE
Just in case that the table is twice in 'thd->handler_tables' (!?!),
Since mysql_ha_flush() is called when the base table has to be closed,
the loop does not break when the table was flushed. If another table
we compare real table names, not aliases. Hence, database names matter.
by that name was found and not flushed, '*was_flushed' is cleared again,
since a pointer to an open HANDLER table is returned.
RETURN
RETURN
*was_flushed Table has been closed due to FLUSH TABLE.
0 ok
NULL A HANDLER Table by that name does not exist (any more).
!= NULL Pointer to the TABLE structure.
