Dropping an user defined function may cause server crash in
case this function is still in use by another thread.

The problem was that our hash implementation didn't update
hash link list properly when hash_update() was called.


mysys/hash.c:
  The following requirement wasn't met by hash_update() function
  causing corruption of hash links list:
  
  After a record was unlinked from the old chain during update, it
  holds random position. By the chance this position is equal to
  position for the first element in the new chain. That means
  updated record is the only record in the new chain.

we use net->vio in my_net_local_init, but in the my_net_init
implementation we set it after the call, so work with unspecified
net->vio value

  Bug #29117 (init_file test crashes with embedded server)
  
  as we started using net->vio in my_net_local_init, we should set
  it before the call

	protocol

One could send a malformed packet that caused the server to SEGV.  In 
recent versions of the password protocol, the client tells the server 
what length the ciphertext is (almost always 20).  If that length was
large enough to overflow a signed char, then the number would jump to 
very large after being casted to unsigned int.

Instead, cast the *passwd char to uchar. 



sql/sql_parse.cc:
  Cast *passwd to get rid of the sign, so that sign extension doesn't
  cause the sequence 125, 126, 127, 4294967169, 4294967170.

Still part of the fix for bug#27078.


libmysqld/lib_sql.cc:
  Some platforms need a cast.
  Still part of the fix for bug#27078.

but rather use the "thread_id" counter.

Fixes bug#27078:
Compile error: lib_sql.cc cast from 'THD*' to 'pthread_t' loses precision


libmysqld/lib_sql.cc:
  Avoid casting a pointer to a (possibly) int, which will not compile on some platforms:
  Do not use the "thd" pointer to identify a thread in the embedded lib,
  but rather use the "thread_id" counter.
  
  Patch is proposed by Monty.  Fixes bug#27078.
