Changes from MySQL to fix build issue.

Fix compilation warning in Hot Backup:

innodb/fil/fil0fil.c: In function 'fil_load_single_table_tablespace':
innodb/fil/fil0fil.c:3253: warning: format '%lld' expects type 'long long int', but argument 6 has type 'ib_int64_t'

When scanning a directory readdir() is called and stat() after it,
if a file is deleted between the two calls stat will fail and the
whole precedure will fail. Change this behavior to continue with the
next entry if stat() fails because of nonexistent file. This is
transparent change as it will make it look as if the file was deleted
before the readdir() call.

This change is needed in order to fix
https://svn.innodb.com/mantis/view.php?id=174
in which we need to abort if os_file_readdir_next_file()
encounters "real" errors.

Approved by:	Marko, Pekka (rb://177)

(issue#186). This functionality is moved to Hot Backup source tree.

Add os_file_is_same() function for Hot Backup (inside ifdef UNIV_HOTBACKUP).
This is part of the fix for Issue #186.
Note! The Windows implementation is incomplete.

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.

Reported as bug#47763.

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.

ha_innobase::index_read(): When the index cannot be found,

ha_innobase::change_active_index(): When prebuilt->index == NULL,
set also prebuilt->index_usable = FALSE.  This is not needed for
correctness, because prebuilt->index_usable is only checked by
row_search_for_mysql(), which requires prebuilt->index != NULL.

btr_page_reorganize_low(): On compression failure, do not restore
those page header fields that should not be affected by the
reorganization.  Instead, compare the fields.

page_zip_decompress(): Add the parameter ibool all, for copying all
page header fields.  Pass the parameter all=TRUE on block read
completion, redo log application, and page_zip_validate(); pass
all=FALSE in all other cases.

page_zip_reorganize(): Do not restore the uncompressed page on
failure.  It will be restored (to pre-modification state) by the
caller anyway.

InnoDB has crashed during table creation.  Also, refuse to start if
files with duplicate tablespace identifiers are encountered.

fil_node_create(): Update fil_system->max_assigned_id.  This should
prevent the reuse of a space->id when InnoDB does a full crash
recovery and invokes fil_load_single_table_tablespaces().  Normally,
fil_system->max_assigned_id is initialized from
SELECT MAX(ID) FROM SYS_TABLES.

fil_open_single_table_tablespace(): Return FALSE when
fil_space_create() fails.

fil_load_single_table_tablespace(): Exit if fil_space_create() fails
and innodb_force_recovery=0.

Left over from r5950.

Tested with MySQL 5.1.38 and 5.1.30.

Starting at 5.1.38, MySQL server exports symbols needed
for dynamic plugin on Windows. There is no need for
Windows specific loading. Also, the CMake files are
simplified in 5.1.38.

When WITH_INNOBASE_STORAGE_ENGINE is specified during
configuration (win\configure.js), InnoDB is built as
a static library. Otherwise, a dynamic InnoDB will be
built (ha_innodb.dll).

CMakeLists.txt requires minor changes in order to work
with MySQL prior to 5.1.38. The changes will be in a
separate patch.

This patch addresses Mantis issue#286.

Should be innodb_open_files, spotted by Michael.
