Before the patch, a value of 9.99 in a FLOAT column came out of mysqli
as 9.9998998641968. This is because it would naively cast a 4-byte float
into PHP's internal 8-byte double.
To fix this, with GCC we use the built-in decimal support to "up-convert"
the 4-byte float to a 8-byte double.
When that is not available, we fall back to converting the float
to a string and then converting the string to a double. This mimics
what MySQL does.
unchecked buffer size. This can be easily workarouned on
existing unpatched systems by increasing
mysqlnd.net_cmd_buffer_size ini variable to more than 8k

Binding params doesn't work when selecting a date inside a CASE-WHEN
(http://bugs.mysql.com/bug.php?id=49406)
The MySQL server sends MYSQL_TYPE_NEWDATE values as clear text, even
when PS are used and thus the binary protocol are used. Changing the
handler for the type.

Fix inconsistencies
- memory allocated with spprintf, or likes, outside of mysqlnd's
allocator functions should not be freed by the mysqlnd's allocator
(a wrapper around emalloc/malloc).
- memory allocated by the mysqlnd's allocator should only be freed
by it.
- add a mode to track memory usage (malloc/free)

needed to move to a new structure MYSQLND_STMT. Makes
the code cleaner and less error-prone.
Also fix PDO/MySQL which directly touch mysqlnd internals
instead of using API calls.
