Bug#26664 test suite times out on OS X 64bit

 - The "mysql client in mysqld"(which is used by
   replication and federated) should use alarms instead of setting
   socket timeout value if the rest of the server uses alarm. By
   always calling 'my_net_set_write_timeout'
   or 'my_net_set_read_timeout' when changing the timeout value(s), the
   selection whether to use alarms or timeouts will be handled by
   ifdef's in those two functions. 
 - Move declaration of 'vio_timeout' into "vio_priv.h"


include/mysql_com.h:
  Move the net_set_*_timeout function declarations to mysql_com.h and
  rename to my_net_set_*_timeout to avoid name clashes
include/violite.h:
  Move declaration of 'vio_timeout' to vio_priv.h (to make
  the function as private as possible)
libmysql/libmysql.c:
  Use my_net_read_timeout or my_net_write_timeout when setting
  the timeouts. Move the global variables for my_net_read/my_write_timeout
  into the only place where they are used. Thus removing them...
server-tools/instance-manager/mysql_connection.cc:
  Use my_net_read_timeout or my_net_write_timeout when setting the timeouts
sql-common/client.c:
  Use my_net_read_timeout or my_net_write_timeout when setting the timeouts
sql/mysql_priv.h:
  Move the net_set_*_timeout function declarations to mysql_com.h
sql/net_serv.cc:
  No need to cast the net->write_timeout value from "uint" to "uint"
sql/set_var.cc:
  Rename net_set_*_timeout to my_net_set_*_timeout
sql/sql_client.cc:
  Use my_net_read_timeout or my_net_write_timeout when setting the timeouts
sql/sql_parse.cc:
  Rename net_set_*_timeout to my_net_set_*_timeout
sql/sql_repl.cc:
  Rename net_set_*_timeout to my_net_set_*_timeout
vio/vio_priv.h:
  Move declaration of 'vio_timeout' to vio_priv.h
vio/viosocket.c:
  Cleanup 'vio_timeout'
   - Use "const void*" on POSIX and "const char*" on windows for
     setsockopt
   - Add DBUG_PRINT's
   - Add comment about why we don't have an implementation of
    vio_timeout for platforms not supporting SO_SNDTIMEO or SO_RCVTIMEO
