Applied Antony T Curtis patch for declaring many CHARSET objects as const

Removed compiler warnings

extra/libevent/epoll.c:
  Removed compiler warnings
extra/libevent/evbuffer.c:
  Removed compiler warnings
extra/libevent/event.c:
  Removed compiler warnings
extra/libevent/select.c:
  Removed compiler warnings
extra/libevent/signal.c:
  Removed compiler warnings
include/m_ctype.h:
  Define CHARSET_INFO, MY_CHARSET_HANDLER, MY_COLLATION_HANDLER, MY_UNICASE_INFO, MY_UNI_CTYPE and MY_UNI_IDX as const structures.
  Declare that pointers point to const data
include/m_string.h:
  Declare that pointers point to const data
include/my_sys.h:
  Redefine variables and function prototypes
include/mysql.h:
  Declare charset as const
include/mysql.h.pp:
  Declare charset as const
include/mysql/plugin.h:
  Declare charset as const
include/mysql/plugin.h.pp:
  Declare charset as const
mysys/charset-def.c:
  Charset can't be of type CHARSET_INFO as they are changed when they are initialized.
mysys/charset.c:
  Functions that change CHARSET_INFO must use 'struct charset_info_st'
  Add temporary variables to not have to change all_charsets[] (Which now is const)
