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.

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.

* Use INNODB_CFLAGS insead of cluttering CFLAGS with InnoDB specific
  flags. CFLAGS are used to compile every file in the MySQL source tree.

* Add INNODB_DYNAMIC_CFLAGS to the flags of the dynamic plugin and use
  -prefer-non-pic to make the dynamic plugin faster on i386.

Use CFLAGS instead of INNODB_CFLAGS to avoid having incompatible flags
inserted in CFLAGS and INNODB_CFLAGS and to avoid compiling mysql and

Fix Bug#36169 create innodb compressed table with too large row size crashed

Sometimes it is possible that
row_drop_table_for_mysql(index->table_name, trx, FALSE); is invoked in
row_create_index_for_mysql() when the index object is freed so copy the
table name to a safe place beforehand and use the copy.

Under some conditions MySQL calls ::open with search_latch leading
to a deadlock as we try to acquire dict_sys->mutex inside ::open
breaking the latching order. The fix is to release search_latch.

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.

Fix of issue# 4

Fixed a timing hole where a thread dropping an index can free the
in-memory index struct while another thread is still using
that structure to remove entries from adaptive hash index belonging
to one of the pages that belongs to the index being dropped.

The fix is to have a reference counter in the index struct and to
wait for this counter to drop to zero beforing freeing the struct.

If it fails on all calls then return error to the caller to be handled

Bug#37671 crash on prepared statement + cursor + geometry + too many open files!
if mysql_execute_command() returns error then free materialized_cursor object.
is_rnd_inited is added to satisfy rnd_end() assertion
(handler may be uninitialized in some cases)

Removed values with more than 15 significant digits from the test case. Results of 
reading/printing such values using system library functions depend on implementation 
and thus are not portable.

Problem:
 XML syntax parser allowed to use quoted strings as attribute names,
 and tried to put them into parser state stack instead of identifiers.
 After that parser failed, if quoted string contained some slash characters.
Fix:
 - Disallowing quoted strings in regular tags.
 - Allowing quoted string in DOCTYPE declararion, but
 don't push it into parse state stack (just skip it).

Field_varstring::store
      
The code that temporary saved the bitmaps of the read set and the write set so that
it can set it to all columns for debug purposes was not expecting that the
table->read_set and table->write_set can be the same. And was always saving both in 
sequence.
As a result the original value was never restored.
Fixed by saving & restoring the original value only once if the two sets are the
same (in a special set of functions).
