Simplify the compile time checks by splittig them into 5 independent checks:

* Whether GCC atomics are available
* Whether pthread_t can be used by GCC atomics
* Whether Solaris libc atomics are available
* Whether pthread_t can be used by Solaris libs atomics
* Checking the size of pthread_t

Include ut0auxconf.h only if none of the macros it would define is defined.
The check when to include this header was outdated from the time when there
was only one macro involved.

Move the atomics checks that are in univ.i outside of
#if windows ... #else ... #endif
This simplifies the code and removes some duplicates like defining
HAVE_ATOMIC_BUILTINS if HAVE_WINDOWS_ATOMICS is defined in both branches.

Do not define the same macro HAVE_ATOMIC_PTHREAD_T for different events.
Instead define HAVE_IB_ATOMIC_PTHREAD_T_GCC and
HAVE_IB_ATOMIC_PTHREAD_T_SOLARIS.

caller anyway.

branches/zip: Clean up after a crash during DROP INDEX.
When InnoDB crashes while dropping an index, ensure that
the index will be completely dropped during crash recovery.

row_merge_drop_index(): Before dropping an index, rename the index to
start with TEMP_INDEX_PREFIX_STR and commit the change, so that
row_merge_drop_temp_indexes() will drop the index after crash
recovery if the server crashes while dropping the index.

fseg_inode_try_get(): New function, forked from fseg_inode_get().
Return NULL if the file segment index node is free.

fseg_inode_get(): Assert that the file segment index node is not free.

fseg_free_step(): If the file segment index node is already free,
print a diagnostic message and return TRUE.

fsp_free_seg_inode(): Write a nonzero number to FSEG_MAGIC_N, so that
allocated-and-freed file segment index nodes can be better
distinguished from uninitialized ones.

This is rb://174, addressing Issue #348.

Tested by restarting mysqld upon the completion of the added
log_write_up_to() invocation below, during DROP INDEX.  The index was
dropped after crash recovery, and re-issuing the DROP INDEX did not
crash the server.

Do not invalidate buffer pool while an LRU batch is active. Added
code to buf_pool_invalidate() to wait for the running batches to finish.

This patch also resets the state of buf_pool struct at invalidation. This
addresses the concern where buf_pool->freed_page_clock becomes non-zero
because we read in a system tablespace page for file format info at
startup.

Include ut0auxconf.h only if none of the macros it would define is defined.
The check when to include this header was outdated from the time when there
was only one macro involved.

Move the atomics checks that are in univ.i outside of
#if windows ... #else ... #endif
This simplifies the code and removes some duplicates like defining
HAVE_ATOMIC_BUILTINS if HAVE_WINDOWS_ATOMICS is defined in both branches.

Do not define the same macro HAVE_ATOMIC_PTHREAD_T for different events.
Instead define HAVE_IB_ATOMIC_PTHREAD_T_GCC and
HAVE_IB_ATOMIC_PTHREAD_T_SOLARIS.

It is not clear why recv_recover_page_func() is updating FIL_PAGE_LSN

page when it is flushed to disk, in buf_flush_init_for_writing().
I noticed this inconsistency when analyzing Issue #313, but this patch
does not fix it.  That is no surprise, since FIL_PAGE_LSN should only
matter on disk files, not in the buffer pool.

buf_LRU_old_threshold_ms: New variable, corresponding to
innodb_old_blocks_time. The value 0 is the default behaviour: no
timeout before making blocks 'new'.

bpage->accessed, bpage->LRU_position, buf_pool->ulint_clock: Remove.

buf_LRU_old_ratio_update(), innobase_old_blocks_pct_update(): Update

buf_page_peek_if_too_old(): Compare ut_time_ms() to bpage->access_time

branches/zip: Fix a critical bug in fast index creation that could
corrupt the created indexes.

row_merge(): Make "half" an in/out parameter. Determine the offset of
half the output file. Copy the last blocks record-by-record instead of
block-by-block, so that the records can be counted. Check that the
input and output have matching n_rec.

row_merge_sort(): Do not assume that two blocks of size N are merged
into a block of size 2*N. The output block can be shorter than the
input if the last page of each input block is almost empty. Use an
accurate termination condition, based on the "half" computed by
row_merge().

row_merge_read(), row_merge_write(), row_merge_blocks(): Add debug output.

merge_file_t, row_merge_file_create(): Add n_rec, the number of records
in the merge file.

row_merge_read_clustered_index(): Update n_rec.

row_merge_blocks(): Update and check n_rec.

row_merge_blocks_copy(): New function, for copying the last blocks in
row_merge().  Update and check n_rec.

This bug was discovered with a user-supplied test case that creates an
index where the initial temporary file is 249 one-megabyte blocks and
the merged files become smaller. In the test, possible merge record
sizes are 10, 18, and 26 bytes.

branches/zip  bug#42885  rb://148

The call to put IO threads to sleep was most probably meant for Windows
only as the comment in buf0rea.c suggests. However it was enabled on
all platforms. This patch restricts the sleep call to windows. This
approach of not putting threads to sleep makes even more sense because
now we have multiple threads working in the background and it probably
is not a good idea to put all of them to sleep because a user thread
wants to post a batch for readahead.

branches/zip: Fix bug# 46650:  Innodb assertion autoinc_lock == lock in lock_table_remove_low on INSERT SELECT

We only store the autoinc locks that are granted in the transaction's autoinc
lock vector. A transacton, that has been rolled back due to a deadlock because
of an AUTOINC lock attempt, will not have added that lock to the vector. We
need to check for that when we remove that lock.

branches/zip: lock_rec_validate_page(): Add the parameter zip_size.
This should help track down Mantis Issue #289.

The pthread_cond_wait implementations for windows might
dead lock in some rare circumstances.

1) One thread (I) enter a timed wait and at a point in
   time ends up after mutex unlock and before
   WaitForMultipleObjects(...)
2) Another thread (II) enters pthread_cond_broadcast.
   Grabs the mutex and discovers one waiter. It set
   the broadcast event and closes the broadcast gate
   then unlocks the mutex.
3) A third thread (III) issues a pthread_cond_signal.
   It grabs the mutex, discovers one waiter, sets the
   signal event then unlock the mutex.
4) The first threads (I) enters WaitForMultipleObjects
   and finds out that the signal object is in a
   signalled state and exits the wait.
5) Thread (I) grabs the mutex and checks result status.
   The number of waiters is decreased and becomes equal
   to 0. The event returned was a signal event so the
   broadcast gate isn't opened. The mutex is released.
6) Thread (II) issues a new broadcast. The mutex is
   acquired but the number of waiters are 0 hence
   the broadcast gate remains closed.
7) Thread (I) enters the wait again but is blocked by
   the broadcast gate.

      This fix resolves the above issue by always resetting
      broadcast gate when there are no more waiters in th queue.


mysys/my_wincond.c:
  * Always reset the broadcast gate if there are no more waiters left.

  Let
    - T be a transactional table and N non-transactional table.
    - B be begin, C commit and R rollback.
    - N be a statement that accesses and changes only N-tables.
    - T be a statement that accesses and changes only T-tables.

In RBR, changes to N-tables that happen early in a transaction are not immediately flushed
upon committing a statement. This behavior may, however, break consistency in the presence
of concurrency since changes done to N-tables become immediately visible to other
connections. To fix this problem, we do the following:

  . B N N T C would log - B N C B N C B T C.
  . B N N T R would log - B N C B N C B T R.

Note that we are not preserving history from the master as we are introducing a commit that
never happened. However, this seems to be more acceptable than the possibility of breaking
consistency in the presence of concurrency.
