  ndbcluster requires more ports, this is the reason why builds will not start on multiple builds

    added shared memory config parameter, signum for use in signalling
    added global variable for holdign signum to be used for shared memory connection
    only fiddle with signals if it is set
    simplified common ndb client option handling

Added the get_actual_table_name function that issues a SHOW TABLES LIKE '%s'.  This will get the table 
name in the proper case.  We use this table name rather than the one given on the command line.  This will
prevent problems when importing SQL on Linux that was generated on a Windows platform where case can be
an issue.

mysqldump.c:
  call get_actual_table_name to get the table name in the proper case

Adjusted the "Usage:" string.
Ordered the option recognition in reverse order from "Usage:".

does not work well together". Now using simplier and more correct
implementation of st_lex::unlink_first_table()/link_first_table_back() 
(It also nicely handles case when global table list is created because
of implictly used time zone tables). (2nd attempt)

Fix for bug #7705 "CONVERT_TZ() crashes with subquery/WHERE on index
column". Implemented new approach for caching objects for constant
time zone arguments. Now instead of determining whenever these arguments
are constants and performing time zone lookup at fix_fields() stage, we
do it on first get_date() invocation.

Cleanup of global @@time_zone variable handling.
