and the server suddenly goes away

1. fix broken change user handling (no restart should happen in the normal case)
2. add assert to guarantee that we never send a request to change to the same plugin
3. "fix" plugin string as sent by the client to be able to compare native plugins by pointers
4. more complete MYSQL initialization in the embedded case
5. change_user.test updated to handle -with-embedded-privilege-control builds

Add a -nobuild argument to the script. Useful for building the zip file release with Express Edition which doesn't have the devenv command

replication thread or when opening a table

  consistency: don't use "index" and "key" interchangeably
  => rename "key" to "index"
  consistency: all option types are logical, besides ULL
  => rename ULL to NUMBER
  don't accept floats where integers are expected
  accept hexadecimal where integers are expected
