Refactoring code to add parameter to pack() and unpack() functions with
purpose of indicating if data should be packed in little-endian or
native order. Using new functions to always pack data for binary log
in little-endian order. The purpose of this refactoring is to allow
proper implementation of endian-agnostic pack() and unpack() functions.
Eliminating several versions of virtual pack() and unpack() functions
in favor for one single virtual function which is overridden in
subclasses.
Implementing pack() and unpack() functions for some field types that
packed data in native format regardless of the value of the
st_table_share::db_low_byte_first flag.
The field types that were packed in native format regardless are:
Field_real, Field_decimal, Field_tiny, Field_short, Field_medium,
Field_long, Field_longlong, and Field_blob.
Before the patch, row-based logging wrote the rows incorrectly on
big-endian machines where the storage engine defined its own
low_byte_first() to be FALSE on big-endian machines (the default
is TRUE), while little-endian machines wrote the fields in correct
order. The only known storage engine that does this is NDB. In effect,
this means that row-based replication from or to a big-endian
machine where the table was using NDB as storage engine failed if the
other engine was either non-NDB or on a little-endian machine.
With this patch, row-based logging is now always done in little-endian
order, while ORDER BY uses the native order if the storage engine
defines low_byte_first() to return FALSE for big-endian machines.
In addition, the max_data_length() function available in Field_blob
was generalized to the entire Field hierarchy to give the maximum
number of bytes that Field::pack() will write.

sql/field.cc:
Eliminating all two-argument pack() and unpack() functions and moving
functionality into the four-argument version. The four argument version
is introduced so that it is possible to avoid using the storage engine
default when writing and reading the packed format (the unpacked format
still uses the storage engine's default). This is used by row-based
replication to write the fields in a storage engine- and endian-agnostic
format.
Packing integral and floating-point numbers in little-endian format
(if requested).
Using pad_char for the field instead of spaces (0x20) when unpacking.
Adding some Doxygen documentation.
---
Adding max_data_length() to denote the maximum number of bytes that
pack() will write.
Adding casts to remove warnings for debug printouts.
sql/field.h:
Eliminating all virtual pack() and unpack() functions except the four-
argument version, which now is the function that shall be overridden.

to code that uses these.

little-endian format, if requested.

Adding max_data_length() to denote the maximum number of bytes that
pack() will write.

c++config.h now has the following code:
// For example, <windows.h> is known to #define min and max as macros...
#undef min
#undef max
So, our defines in my_global.h are undefined when <new> header
is included.
Move definitions of min()/max() to the end of my_global.h.
Invaldating a subset of a sufficiently large query cache can take a long time.
During this time the server is efficiently frozen and no other operation can
be executed. This patch addresses this problem by setting a time limit on
how long time a dictionary access request can take before giving up on the
attempt. This patch does not work for query cache invalidations issued by
DROP, ALTER or RENAME TABLE operations.
sql/sql_cache.cc:
Changed mutex locking to a timed spinn lock. If access to query cache dictionary
takes "a long time" (currently more than 0.1 seconds) the system fall backs on
ordinary statement execution.
