The bug caused memory corruption for some queries with top OR level
in the WHERE condition if they contained equality predicates and
other sargable predicates in disjunctive parts of the condition.
The corruption happened because the upper bound of the memory
allocated for KEY_FIELD and SARGABLE_PARAM internal structures
containing info about potential lookup keys was calculated incorrectly
in some cases. In particular it was calculated incorrectly when the
WHERE condition was an OR formula with disjuncts being AND formulas
including equalities and other sargable predicates.
mysql-test/r/select.result:
Added a test case for bug #30396.
mysql-test/t/select.test:
Added a test case for bug #30396.
sql/item_cmpfunc.h:
Removed max_members from the COND_EQUAL class as not useful anymore.
sql/sql_base.cc:
Added the max_equal_elems field to the st_select_lex structure.
sql/sql_lex.cc:
Added the max_equal_elems field to the st_select_lex structure.
sql/sql_lex.h:
Added the max_equal_elems field to the st_select_lex structure.
The field contains the maximal number of elements in multiple equalities
built for the query conditions.

The max_equal_elems field to the st_select_lex structure is used now
to calculate the above mentioned upper bound. The field contains the
maximal number of elements in multiple equalities built for the query
conditions.

Faster thr_alarm()
Added 'Opened_files' status variable to track calls to my_open()
Don't give warnings when running mysql_install_db
Added option --source-install to mysql_install_db
I had to do the following renames() as used polymorphism didn't work with Forte compiler on 64 bit systems
index_read() -> index_read_map()
index_read_idx() -> index_read_idx_map()
index_read_last() -> index_read_last_map()
BUILD/compile-solaris-sparc-forte:
Updated script to current Solaris installations

mysys/my_fopen.c:
Count number of opened files
mysys/my_open.c:
Count number of opened files
mysys/my_static.c:
Count number of opened files
mysys/thr_alarm.c:
Optimization to do less alarm() and pthread_sigmask() calls.
Idea is to remember time for next pending alarm and not reschedule a new alarm if it's after the current one.
Before we only did this if there was other pending alarms.
We don't have to use pthread_sigmask() in case of 'USE_ONE_SIGNAL_HAND' as the alarm()
signal will be blocked for the calling thread anyway and no other thread will have the alarm() signal enabled to call process_alarm()

Modified functions which are used during open table process
according to table opening method and requested_object.
sql/sql_select.cc:
Add support for I_S tables into select_describe() function
sql/sql_show.cc:
1. Added initialization of 'open_method' to 'st_field_info' structs.
2. Added initialization of 'i_s_requested_object' to 'ST_SCHEMA_TABLE' structs.
3. New function which calculates database name and table name values
from 'where' condition if it's possible
void get_lookup_field_values(THD *thd, COND *cond, TABLE_LIST *table,
LOOKUP_FIELD_VALUES *lookup_field_vals);
4. New function which set table open method
setup_table_open_method(TABLE_LIST *tables,
ST_SCHEMA_TABLE *schema_table,
enum enum_schema_tables schema_table_idx)
5. New function
int make_db_list(THD *thd, List<LEX_STRING> *files,
LOOKUP_FIELD_VALUES *lookup_field_vals,
bool *with_i_schema)
6. New function
int make_table_name_list(THD *thd, List<LEX_STRING> *files, LEX *lex,
LOOKUP_FIELD_VALUES *lookup_field_vals,
bool with_i_schema, LEX_STRING *db_name)
7. Modified 'get_all_tables' function according to new schema(see wl#3732).
sql/sql_show.h:
char* variables are changed to LEX_STRING
sql/table.cc:
Modified functions which are used during open table process
according to table opening method and requested_object.
sql/table.h:
1. added new constants(open_method)
#define SKIP_OPEN_TABLE 0
#define OPEN_FRM_ONLY 1
#define OPEN_FULL_TABLE 2
2. Added new field 'open_method' into struct st_field_info;
uint open_method;
3. Added new field into ST_SCHEMA_TABLE struct
uint i_s_requested_object; /* the object we need to open(TABLE | VIEW) */.
4. Added new field to TABLE_LIST struct.
uint i_s_requested_object;
This field is set from ST_SCHEMA_TABLE.i_s_requested_object
for processed table before opening.
5. Added new fields to TABLE_LIST struct, used for 'explain select' for I_S table
bool has_db_lookup_value;
bool has_table_lookup_value;
uint table_open_method;
sql/unireg.h:
added new constants
This patch adds cost estimation for the queries with ORDER BY / GROUP BY
and LIMIT.
If there was a ref/range access to the table whose rows were required
to be ordered in the result set the optimizer always employed this access
though a scan by a different index that was compatible with the required
order could be cheaper to produce the first L rows of the result set.
Now for such queries the optimizer makes a choice between the cheapest
ref/range accesses not compatible with the given order and index scans
compatible with it.

Use size_t instead of uint when calculating join buffer size, because uint can be overflown on 64-bit platforms and join_buffer_size > 4 GB.
The test case for this bug is a part of the test suite for bug #5731.

- Don't call mysql_select() several times for the select that enumerates
a temporary table with the results of the UNION. Making this call for
every subquery execution caused O(#enumerated-rows-in-the-outer-query)
memory allocations.
- Instead, call join->reinit() and join->exec(), and
= disable constant table detection for such joins,
= provide special handling for table-less constant subqueries.
