21913: DATE_FORMAT() Crashes mysql server if I use it through mysql-connector-j driver.

Variable character_set_results can legally be NULL (for "no conversion.")
This could result in a NULL deref that crashed the server.  Fixed.

(Although ran some additional precursory tests to see whether I could break
anything else, but no breakage so far.)

  Bug#21913: DATE_FORMAT() Crashes mysql server if I use it through mysql-connector-j driver.
  
  Prove DATE_FORMAT() no longer crashes the server when character_set_results is
  NULL (which is a legal value and means, "no conversion").

  Avoid NULL deref in my_charset_same() -- if !to_cs, we won't need to compare
  because it is magic for, "no conversion."

Zero-length variables caused failures when using the length to look
up the name in a hash.  Instead, signal that no zero-length name can
ever be found and that to encounter one is a syntax error.


mysql-test/r/variables.result:
  Results for test.
mysql-test/t/variables.test:
  Insert tests to prove that zero-length variable names do not cause
  faults.
sql/gen_lex_hash.cc:
  If the length is zero, then there is nothing to look-up in the 
  hash.
sql/sql_lex.cc:
  Names of variables must not be empty.  Signal an error of that 
  happens.

Too many cursors (more than 1024) could lead to memory corruption.
This affects both, stored routines and C API cursors, and the
threshold is per-server, not per-connection.  Similarly, the
corruption could happen when the server was under heavy load
(executing more than 1024 simultaneous complex queries), and this is
the reason why this bug is fixed in 4.1, which doesn't support
cursors.

The corruption was caused by a bug in the temporary tables code, when
an attempt to create a table could lead to a write beyond allocated
space.  Note, that only internal tables were affected (the tables
created internally by the server to resolve the query), not tables
created with CREATE TEMPORARY TABLE.  Another pre-condition for the
bug is TRUE value of --temp-pool startup option, which, however, is a
default.

The cause of a bug was that random memory was overwritten in
bitmap_set_next() due to out-of-bound memory access.
