Change string->float conversion to delay division as long as possible.
This gives us more exact integer->float conversion for numbers of type '123.45E+02' (Bug #7740)
Lots of small fixes to multi-precision-math path
Give Note for '123.4e'
Added helper functions type 'val_string_from_real()
Don't give warnings for end space for string2decimal()
Changed storage of values for SP so that we can detect length of argument without strlen()
Changed interface for str2dec() so that we must supple the pointer to the last character in the buffer
Proposal to fix this problem: when using libmysqlclient, you must call mysql_server_end() to nicely free memory at the end
of your program; it however sounds weird to call a function named *SERVER_end* when you're the CLIENT (you're not ending the server, you're ending
your ability to talk to servers). So here I add two defines which should be more generic names. Our manual
mentions these functions only for libmysqld API so needs some fixing, and then we can close BUG#8099 and BUG#6149.

So here I add two defines which should be more generic names. This was longly discussed with Konstantin, Serg, Brian. The problem started from
a post on valgrind-users list: http://sourceforge.net/mailarchive/forum.php?thread_id=5778035&forum_id=32038 ; our manual mentions these functions
only for libmysqld API so needs some fixing, and then we can close BUG#8099 and BUG#6149.
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.
* Removed unused parameters
* Fixed several cost calculation errors in ror_intersect_add
* Better code structure for ror_intersect_add and get_best_ror_intersect
