Bug #29644: alter table hangs if records locked in share mode 
by long running transaction

On Windows opened files can't be deleted. There was a special
upgraded lock mode (TL_WRITE instead of TL_WRITE_ALLOW_READ) 
in ALTER TABLE to make sure nobody has the table opened
when deleting the old table in ALTER TABLE. This special mode
was causing ALTER TABLE to hang waiting on a lock inside InnoDB.
This special lock is no longer necessary as the server is 
closing the tables it needs to delete in ALTER TABLE.
Fixed by removing the special lock.
Note that this also reverses the fix for bug 17264 that deals with
another consequence of this special lock mode being used.

One test case in innodb.test fails because of auto-increment
changes in r1562:1653:

$diff innodb.result innodb.reject
504c504
< 3	test2		this will work
---
> 4	test2		this will work

* Use standard while-loop instead of the seq command

is one test that fails as of this commit. The updated test case should be
part of the snapshot from MySQL shortly.

Fix for bug# 27950 - Init AUTOINC from delete_row().

Fix for bug# 28781 - Use value specified by MySQL, in update_row().

Summary of structural changes:
==============================
InnoDB needs to hold a table level lock for AUTOINC allocations to overcome
the non-determinism inherent in MySQL SBR for INSERT ... SELECT. In this fix 
for simple INSERT statements (including multi-value inserts), we try and avoid
acquiring the special AUTOINC table level lock unless another transaction has
already reserved the AUTOINC table level lock, in which case we fall back
to the old behavior of acquiring the AUTOINC table level lock.

The max AUTOINC value is now read directly using the low level interface
of InnoDB.

queues. Supports table and record lock queues via the same interface.

There is only "get previous" method because currently there is no need
for "get next" - it would be unused. Feel free to add one if needed.

* lock0lock.c: remove lock_get_type() and include include/lock0priv.ic
* lock0priv.h: include lock0priv.ic and add lock_get_type() prototype
* Makefile.am: add lock0priv.ic to noinst_HEADERS
* lock0priv.ic: introduce this new file containing the body of
  lock_get_type()

This move is necessary in order to use lock_get_type() from other lock/
source files (it's going to be used in lock/lock0iter.c).

in order to determine which lock is blocking which. Make it non-static
and put its definition in include/lock0lock.h.

Approved by:	Heikki (via IM)

Suggested by:	Sunny

This is needed in order to add more code to lock/ that uses members of
these structures (internal to the lock module) but in a separate file,
rather than lock0lock.c. lock0lock.c is a way too big already.

by typecasting the variables before multiplying them, so that the result of
the multiplication is of type "unsigned long long".

I verified this fix by creating a sparse file of 6TB and forcing InnoDB to
use it without overwriting it with zeroes (by commenting the code that
overwrites :newraw files).

New type ullint is introduced with the sole purpose of shortening
"unsigned long long", please do not define it to something else than
"unsigned long long".

trx->sess or trx_dummy_sess is non-NULL.

page_get_free_space_of_empty_noninline() by 2.  Until r1571, that function
did not return the same value as page_get_free_space_of_empty().

that was introduced in r1571.  Inlining is disabled in ha_innodb.cc.

When creating an index containing a too long record, InnoDB would
dereference a NULL pointer when trying to determine the maximum row length.

innodb_check_for_record_too_big_error(): Replace the dict_table_t*
parameter with a Boolean flag.  There is not always a dict_table_t object
when this function is called.

page_get_free_space_of_empty_noninline(): Move the definition and
declaration from row0mysql (!) to page0page.  Make the signature
identical with page_get_free_space_of_empty().

create_clustered_index_when_no_primary(): Add the parameter "comp".
Remove unnecessary casts.

records in ROW_FORMAT=COMPACT is REC_N_NEW_EXTRA_BYTES + 8.  The
REC_N_NEW_EXTRA_BYTES was accidentally omitted in r1546.  This function
should never be called on those records, though.

prebuilt->sql_stat_start.  In an ALTER TABLE statement in the innodb_gis
test, an ut_ad() assertion failed, because no IX lock had been acquired
on the table, because prebuilt->sql_stat_start was inadvertently reset
to FALSE, by this function.  This function was called via
ha_innobase::info() and mysql_prepare_alter_table().
