The patch implements the idea suggested by Olaf van der Spek in
thread "Client: many small reads?" (internals@lists.mysql.com).
Now small reads performed by the client library are buffered.
The buffering gives up to 2 times speedup when retrieving
one-column tables.
BUILD/SETUP.sh:
Remove --with-vio option which no longer exist.
BUILD/compile-pentium64-valgrind-max:
Remove --with-vio option which no longer exist.
config/ac-macros/misc.m4:
Removed --with-vio configure switch: we always use VIO. The switch,
in fact, only saved us one pointer dereferencing per call in case we had
only one transport type in VIO enabled.
config/ac-macros/openssl.m4:
Removed HAVE_VIO.
include/config-win.h:
Removed HAVE_VIO (not needed anymore)
Added HAVE_VIO_READ_BUFF (define buffered client reads for Windows clients).
include/violite.h:
Removed HAVE_VIO, as currently VIO is always in use.
Added declaration for vio_read_buff and related members in struct VIO.
sql-common/client.c:
Use flags to set up vio read buffering in mysql_real_connect.
sql/mysqld.cc:
Use flags to disable vio read buffering when creating a server
connection.
vio/vio.c:
Optionally set up vio read buffer when creating a new VIO structure.
vio/viosocket.c:
Implementation of client-side buffered reads in VIO: the idea
is to buffer small reads in a client buffer to save amount of
syscalls per retrieved result set. The implementation relies
on the fact that read/recv will return as soon as there is
some data in the kernel buffer, no matter how big the given
user's buffer is. To be able to disable it in case recv/read don't
have such semantics, the new calls are guarded
with #define HAVE_VIO_READ_BUFF. Currently buffered reading is
switched on only for BSD sockets and named pipes, both on Windows
and UNIXes.

This patch collects all previous patches into one.
The main problem was due to that there is are two variables -
dflt_key_cache and sql_key_cache with have more or less duplicate
function. The reson for the bug was that the default value in the key
cache hash was set to dflt_key_cache, then sql_key_cache was set to a
new key cache object, and then dflt_key_cache was set to sql_key_cache
which was different from the dflt_key_cache_var. After sending SIGHUP,
the server was using the original default value for the key cache hash,
which was different from the actual key cache object used for the
default key cache.

To allow builds without InnoDB ("classic"), the reference to 'innobase_use_checksums' must be guarded by an appropriate '#ifdef' (bug#7961).
sql/mysqld.cc:
more suggestive warning message
sql/sql_class.h:
need a method to see MYSQL_LOG::name (the name of the binlog but without the numeric extension)
or by using --log-bin-index). This is so that he does not have a replication break when his master's
hostname changes. Plus binary logging options consistency checks.
sql/mysqld.cc:
* Encourage user to specify a name for the binlog index file (either by giving an argument to --log-bin,
or by using --log-bin-index). This is so that he does not have a replication break when his master's
hostname changes. Why not a fatal error? To not break existing many-machine setups.
* --log-bin-index without --log-bin does not make sense.
* --log-slave-updates without --log-bin does not either.
