Fix Bug#36600 SHOW STATUS takes a lot of CPU in buf_get_latched_pages_number
by removing the Innodb_buffer_pool_pages_latched variable from
SHOW STATUS output in non-UNIV_DEBUG compilation.

Fix Bug#11894 innodb_file_per_table crashes w/ Windows .sym symbolic
link hack
The crash was due to un-handled error 3 (path not found). In the case
of file per table, change the call to os_file_handle_error_no_exit()
from os_file_handle_error(). Also, checks for full path pattern during
table create (Windows only), which is used in symbolic link and temp
table creation.

code has been tested on a big-endian machine too.

Fix Bug#36819 ut_usectime does not handle errors from gettimeofday
by retrying gettimeofday() several times if it fails in ut_usectime().
If it fails on all calls then return error to the caller to be handled
at higher level.
Update the variable innodb_row_lock_time_max in SHOW STATUS output only
if ut_usectime() was successful.

branches/5.1: Fix for Bug#35602, "Failed to read auto-increment value from
storage engine". The test for REPLACE was an error of ommission since it's
classified as a simple INSERT. For REPLACE statements we don't acquire
the special AUTOINC lock for AUTOINC_NEW_STYLE_LOCKING with this fix.

Fix Bug#36149 Read buffer overflow in srv0start.c found during "make test"
Use strncmp(3) instead of memcmp(3) to avoid reading past end of the string
if it is empty (*str == '\0'). This bug is _not_ a buffer overflow.
Discussed with: Sunny (via IM)

symbols. Use it for all definitions of non-static variables and functions.
lexyy.c, make_flex.sh: Declare yylex as UNIV_INTERN, not static. It is
referenced from pars0grm.c.
Actually, according to
nm .libs/ha_innodb.so|grep -w '[ABCE-TVXYZ]'
the following symbols are still global:
* The vtable for class ha_innodb
* pars0grm.c: The function yyparse() and the variables yychar, yylval, yynerrs
The required changes to the Bison-generated file pars0grm.c will be addressed
in a separate commit, which will add a script similar to make_flex.sh.
The class ha_innodb is renamed from class ha_innobase by a #define. Thus,
there will be no clash with the builtin InnoDB. However, there will be some
overhead for invoking virtual methods of class ha_innodb. Ideas for making
the vtable hidden are welcome. -fvisibility=hidden is not available in GCC 3.
os_aio_simulated_handle() before and after initiating a write. We
cannot easily pass the compressed page sizes to this function. The
check could only be performed on uncompressed pages.
os_aio_simulated_handle(): Temporarily disable os_file_check_page_trailers(),
which cannot be invoked on compressed pages.
dict_table_add_system_columns(): New function, split from
dict_table_add_to_cache().
mlog_parse_index(): Add system columns to the dummy table and identify
DB_TRX_ID and DB_ROLL_PTR in the dummy index.
buf_LRU_get_free_block(): Note that page_zip->data should be allocated from
an aligned memory pool.
buf_flush_buffered_writes(): Write compressed pages to disk.
buf_flush_post_to_doublewrite_buf(): Copy compressed pages to the
doublewrite buffer. Zero fill any excess space.
buf_flush_init_for_writing(): Treat all compressed pages the same.
buf_read_page_low(): Read compressed pages from disk.
buf_page_io_complete(): Process compressed pages.
trx_sys_doublewrite_init_or_restore_page(): Process compressed pages.
mlog_write_initial_log_record_fast(): Enable a debug printout
#ifdef UNIV_LOG_DEBUG.
fsp_header_init(), fsp_fill_free_list(): Pass the compressed page size
to buf_page_create().
page_zip_compress_write_log(): Flatten the if-else if-else logic.
page_zip_parse_write_blob_ptr(): Do not test page_zip if page==NULL.
page_zip_parse_write_node_ptr(): Do not test page_zip if page==NULL.
Invoke mlog_close() correctly.
row_sel_store_row_id_to_prebuilt(): Add UNIV_UNLIKELY hint to an
assertion-like test.
a few places accordingly.
os_aio_simulated_handle(): Add TODO comments about skipping the write
checks for compressed pages.
dict_create_sys_tables_tuple(): Write the compressed page size to
the TYPE column.
open_or_create_data_files(): Simplify the fil_node_create() call.
fil_node_create(): Do not touch space->zip_size. It was already initialized
by fil_space_create().
fil_reset_too_high_lsns(), buf_flush_buffered_writes(): Add TODO comment
about compressed pages.
buf_flush_init_for_writing(): Handle pages of type FIL_PAGE_INODE,
FIL_PAGE_IBUF_BITMAP, and FIL_PAGE_TYPE_FSP_HDR as uncompressed ones.
buf_page_print(): Print also compressed pages. Add parameter zip_size.
buf_flush_init_for_writing(): Stamp the fields on a compressed B-tree index
page.
Add the header field FIL_PAGE_ZBLOB_SPACE_ID as an alias of FIL_PAGE_PREV.
page_zip_calc_checksum(): New function.
page_zip_compress(): Avoid copying the fields that are written in
buf_flush_init_for_writing().
page_zip_header_cmp(): New function for comparing those fields of the
page header that will not be written in buf_flush_init_for_writing().
