(irrelevant for 5.5 and up)

InnoDB Plugin 1.0.14 has been released with MySQL 5.1.54.

This change is relevant only for 5.1.

Do not use nested AC_CHECK_FUNC() because they result in:

./configure: line 52688: syntax error: unexpected end of file

(which happens only on some platforms and does not happen on others,
I have no idea what is the reason for this)

This is a null-merge because Bug#59327 is present only in 5.1

AC_CHECK_FUNCS(f1 f2 f3, ACTION_IF_PRESENT)
ACTION_IF_PRESENT is executed if any of f1, f2 or f3 is present.
Fix this misusage, we want the action to be executed if all of the
functions are present.

Check whether the master and purge thread are active after creating them. Do
not proceed until both threads have started. We do this by checking whether a
slot has been reserved by both the respective threads.
      
Add srv_thread_has_reserved_slot() returns slot no or ULINT_UNDEFINED.

This is 5.1 built-in specific as the dict_table_t strcture is allocated
with mem_heap_zalloc since 5.1 plugin.

Avoid handler::info() call for three Information Schema tables;

This assert could be triggered if -1 was inserted into
an auto increment column by a statement writing more than
one row.

Unless explicitly given, an interval of auto increment values
is generated when a statement first needs an auto increment
value. The triggered assert checks that the auto increment
counter is equal to or higher than the lower bound of this
interval.

Generally, the auto increment counter starts at 1 and is
incremented by 1 each time it is used. However, inserting an
explicit value into the auto increment column, sets the auto
increment counter to this value + 1 if this value is higher
than the current value of the auto increment counter.

This bug was triggered if the explicit value was -1. Since the
value was converted to unsigned before any comparisons were made,
it was found to be higher than the current vale of the auto
increment counter and the counter was set to -1 + 1. This value
was below the reserved interval and caused the assert to be
triggered the next time the statement tried to write a row.

With the patch for Bug#39828, this bug is no longer repeatable.
Now, -1 + 1 is detected as an "overflow" which causes the auto
increment counter to be set to ULONGLONG_MAX. This avoids hitting
the assert for the next insert and causes a new interval of
auto increment values to be generated. This resolves the issue.

This patch therefore only contains a regression test and no code
changes. Test case added to auto_increment.test.

This adds 64 new rows to performance_schema.rwlock_instances.

This patch will make perfschema.binlog_mix perfschema.binlog_row tests fail,
but they will be fixed by http://lists.mysql.com/commits/127862

Fixed the test case to be independent of build options used.
Removed the lowercase-table-names constraint, since performance schema tables are now in lowercase.

so will be run only weekly; this closes BUG#50595.
