Problem: creating an rb-tree key we store length (2 bytes) before the actual data for 
varchar key parts. The fact was missed for NULL key parts, when we set NULL byte and 
skip the rest.

Fix: take into account the length of the varchar key parts for NULLs.

Issue a warning if a user sets an option or a variable to a value that is greater than a defined maximum for the option/variable.

This is for bug #29446 "Specifying a myisam_sort_buffer > 4GB on 64 bit machines not possible". Support for myisam_sort_buffer_size > 4 GB on 64-bit Windows will be looked at later in 5.2.

The patch limits read_buffer_size and read_rnd_buffer_size by 2 GB on all platforms for the following reasons:
  
- I/O code in mysys, code in mf_iocache.c and in some storage engines do not currently work with sizes > 2 GB for those buffers
- even if the above had been fixed, Windows POSIX read() and write() calls are not 2GB-safe, so setting those buffer to sizes > 2GB would not work correctly on 64-bit Windows.

Backport of the keycache changes from http://lists.mysql.com/commits/31517 to make keycache 64-bit safe in 5.0. This is for bug #5731.

Limit join_buffer_size, sort_buffer_size and myisam_sort_buffer_size to 4GB on all platforms, since the related code in 5.0 is not 64-bit safe. This is patch is a part of work on bug #5731 and will be null-merged to 5.1.

This is required to allow key_buffer_size > 4 GB (bug #5731).

 - Merge sslaccept and sslconnect.
 - Atomically "reset" vio to VIO_TYPE_SSL when the SSL connection has
   succeeded, this avoids having to revert anything and thus protects
   against "close_active_vio" in the middle.
 - Add some variance to the testcase

- Fix bug#27265
- Support for fixing bug#18441

1) We do not provide the "isam" table handler in 5.0 and up (different from "myisam" !),
   so we do not need the ".def" files for the "isam"-specific tools.

2) Use "basename" to get the base name of a file, not a harder-to-read sed expression.
