ASSERT_DATAEQ similar to ASSERT_STREQ

[GoogleCodeExporter]

CxxTest has a macro called TS_ASSERT_SAME_DATA.  It is used to compare to
memory regions.

The macro would behave similar to ASSERT_STREQ does now, except it would
print the hex string of the memory regions if they differ.

This is particularly useful for testing POD structs that don't have an
equality or stream operator defined

The idea makes sense.  However, we'd like to control the number of macros, as 
macros 
are bad for many reasons.

Now that Google C++ Mocking Framework (http://code.google.com/p/googlemock/) is 
released, there is a better way to do it.  We can define a matcher BitEq(x) and 
write

  ASSERT_THAT(value, BitEq(x))

to assert that the bytes in value and the bytes in x are equal.  ASSERT_THAT() 
is 
already defined by Google Mock, so there's no new macro to add.  BitEq(x) can 
also be 
used in validating mock function arguments, so it's more useful than an 
ASSERT_DATAEQ 
macro too.

Note that you don't have to use Google Mock's mocking functionality in order to 
use 
ASSERT_THAT().
