Added missing timeout function for named pipes and shared memory (fixes core dump on windows)

Signed auto_increment keys for HASH tables (like for MyISAM tables in 4.0)
nitialize system_charset_info() early. Fixes core dump when starting windows service


heap/hp_hash.c:
  Signed auto_increment keys for HASH tables (like for MyISAM tables in 4.0)
mysql-test/r/create.result:
  More test for type returned by if_null()
mysql-test/t/create.test:
  More test for type returned by if_null()
sql/field.h:
  Remove not needed functions
sql/item.cc:
  Use normal field create function instead of special functions just made for tmp_table_field_from_field_type

  Initialize system_charset_info() early. Fixes core dump when starting windows service

Update auto_increment info
SYNOPSIS
update_auto_increment()
info MyISAM handler
record Row to update
IMPLEMENTATION
Only replace the auto_increment value if it is higher than the previous
one. For signed columns we don't update the auto increment value if it's
less than zero.
