Fixed wrong memory references found by purify

(No really critical errors found, but a few possible wrong results)


innobase/dict/dict0dict.c:
  Replace memcmp with comparison of characters to avoid warnings from purify when 'sptr' points to a very short string
mysql-test/r/select_found.result:
  Add missing drop table
mysql-test/r/type_set.result:
  More tests
mysql-test/t/select_found.test:
  Add missing drop table
mysql-test/t/type_set.test:
  More tests
mysys/my_init.c:
  Avoid warning from purify (purify doesn't handle getrusage() properly)
sql/field.h:
  enum & set are sorted as numbers. This fixes an access to uninitialized memory when enum/set are multi-byte characters
sql/filesort.cc:
  enum & set are sorted as numbers. This fixes an access to uninitialized memory when enum/set are multi-byte characters
sql/item_cmpfunc.cc:
  Fixed warning from purify. (Not critical as the arguments are passed to a function but not used)
  Allocate Arg_comparator() with 'new' instead of sql_alloc() to ensure proper initialization
sql/mysqld.cc:
  Wait for signal handler to stop when running --bootstrap
  (Fixes warning from purify)
sql/sql_insert.cc:
  Initialize slot used by innodb.cc (not critical)
sql/sql_lex.h:
  Better comments
sql/sql_repl.cc:
  memcmp -> bcmp() to avoid warning from purify
sql/sql_select.cc:
  Fix for out-of-bound memory reference when doing DISTINCT on const expressions
strings/ctype-simple.c:
  Fixes to not access uninitialized memory
  (Not critical)
