trigger fails".

In cases when CONVERT_TZ() function was used in trigger or stored function
(or in stored procedure which was called from trigger or stored function)
error about non existing '.' table was reported.

Statements that use CONVERT_TZ() function should have time zone related
tables in their table list. tz_init_table_list() function which is used
to produce part of table list containing those tables didn't set
TABLE_LIST::db_length/table_name_length members properly. As result time
zone tables needed for CONVERT_TZ() function were incorrectly handled by
prelocking algorithm and "Table '.' doesn't exist' error was emitted.
This fix changes tz_init_table_list() in such way that it properly inits
TABLE_LIST::table_name_length/db_length members and thus produces table list
which can be handled by prelocking algorithm correctly.

  Added test for bug #11081 "Using a CONVERT_TZ function in a stored function
  or trigger fails".
mysql-test/t/timezone2.test:
  Added test for bug #11081 "Using a CONVERT_TZ function in a stored function
  or trigger fails".
sql/tztime.cc:
  Now tz_init_table_list() inits table_name_length and db_length members in
  TABLE_LIST objects, so table lists produced with its help can be handled 
  by prelocking algorithm properly.
  
  Also two clean-ups are included:
  - Now we use MY_TZ_TABLES_COUNT instead of magical number 4 in places where
    it is appropriate.
  - TZ_NAMES_ENTRY structure was converted to Tz_names_entry class in order 
    to emphasize its non-POD nature.
sql/tztime.h:
  Added MY_TZ_TABLES_COUNT constant to be used as number of time zone related
  tables which are needed for dynamical loading of time zone descriptions.

Retrieving data from compressed MyISAM table which is bigger than 4G on 32-bit box
with mmap() support results in server crash.

mmap() accepts length of bytes to be mapped in second param, which is 32-bit
size_t. But we pass data_file_length, which is 64-bit my_off_t. As a result only
first data_file_length % 4G were mapped.

This fix adds additional condition for mmap() usage, that is use mmap() for
compressed table which size is no more than 4G on 32-bit platform.


myisam/mi_packrec.c:
  Use mmap() for compressed table which size is no more than 4G on 32-bit platform.

Conversion from int and real numbers to UCS2 didn't work fine: 
CONVERT(100, CHAR(50) UNICODE)
CONVERT(103.9, CHAR(50) UNICODE)

The problem appeared because numbers have binary charset, so,
simple charset recast binary->ucs2 was performed
instead of real conversion.

Fixed to make numbers pretend to be non-binary.

CONNECTION_ID() was implemented as a constant Item, i.e. an instance of
Item_static_int_func class holding value computed at creation time.
Since Items are created on parsing, and trigger statements are parsed
on table open, the first connection to open a particular table would
effectively set its own CONNECTION_ID() inside trigger statements for
that table.

Re-implement CONNECTION_ID() as a class derived from Item_int_func, and
compute connection_id on every call to fix_fields().
