Initialize all MySQL global variables to default values
SYNOPSIS
mysql_init_variables()
NOTES
The reason to set a lot of global variables to zero is to allow one to
restart the embedded server with a clean environment
It's also needed on some exotic platforms where global variables are
not set to 0 when a program starts.
We don't need to set numeric variables refered to in my_long_options
as these are initialized by my_getopt.
