f207b33a7b Support for character set conversion in binary protocol: another go 
after Monty's review.
- Item_param was rewritten.
- it turns out that we can't convert string data to character set of
  connection on the fly, because they first should be written to the binary
  log.
  To support efficient conversion we need to rewrite prepared statements
  binlogging code first.

dlenev@brandersnatch.localdomain
c7fbcbca7a Fix for remaining issues described in Bug #1664 
"mysql_send_long_data() API call is completely broken".

Now we are resetting some members (long_data_supplied/null_value...) of Item_param to its 
initial state after each execution of prepared statement. We also manipulating 
Item_param::maybe_null/null_value only via Item_param::set_* setters which makes code a bit 
more robust.

dlenev@brandersnatch.localdomain
4122188cc2 Fix for Bug #3307 "FLUSH TABLES sometimes breaks prepared statement 
table resolution".
Added members to Item_ident for storing original db, table and field
names since those that set later from Field have shorter life-time 
than required by prep. stmt. So we need to restore original names in 
Item_ident::cleanup(). Also now using special construnctor for creation
of Item_field from Field object that ensures that table and field name 
have big enough life-time.

"Fix" for bug #2050 "10 to 1 performance drop with server 4.1.1"
Clean ups in implementation of caching of field number in table.
Added caching of table in which field is found in find_field_in_tables().

dlenev@brandersnatch.localdomain
9e28b7698d "Fix" for BUG #2050 "10 to 1 performance drop with server 4.1.1". 
Actually it is not a bug but right behavior observed as pefomance 
degradation after we have forced Item_field::fix_fields() to 
re-execute each time when we are executing prep stmt.

This patch implements small optimization which heals this bad 
behavior. We are caching field position in TABLE::field array in
Item's member and are using this position for speeding up field
lookups in fix_fields() in case of its re-execution.

The objects of this class represent multiple conjunctive equalities
in where conditions: =(f1,f2,...fn) <=> f1=f2 and f2= ... and =fn.
The objects are used to generate new possibale paths to access
the tables when executing a query.
They are also used to optimize the execution plan 
chosen by the optimizer for the query.

625371f306 Fix for bug #1500 "Server crash with mysql_prepare" 
We treat Item_param whose value is not set as non-const.
This allows us to avoid use of Item_param's value (not yet existing) in 
those fix_fields and fix_length_and_dec that do calculations if their 
Items arguments are const. So we can call fix_fields for such items from
mysql_prepare safely.

Cleaned up (and disabled part of) date/time/datetime format patch. One can't anymore change default read/write date/time/formats.
This is becasue the non standard datetime formats can't be compared as strings and MySQL does still a lot of datetime comparisons as strings
Changed flag argument to str_to_TIME() and get_date() from bool to uint
Removed THD from str_to_xxxx functions and Item class.
Fixed core dump when doing --print-defaults
Move some common string functions to strfunc.cc
Dates as strings are now of type my_charset_bin instead of default_charset()
Introduce IDENT_QUOTED to not have to create an extra copy of simple identifiers (all chars < 128)
Removed xxx_FORMAT_TYPE enums and replaced them with the old TIMESTAMP_xxx enums
Renamed some TIMESTAMP_xxx enums to more appropriate names
Use defines instead of integers for date/time/datetime string lengths
Added to build system and use the new my_strtoll10() function.

The above query created a field of koi8r charset, not cp1251

Change:
CREATE TABLE a (a CHAR(1) CHARACTER SET utf8) 
Length now means character length, not byte length.
The above creates a field that guarantees can store a multibyte value
1 character long. For utf8 the above creates a field that can store
3 bytes.
