[Gnash] container.h changes

[Jim Garrison]

Hello

Earlier this evening I committed some code that removes the custom 
implementation of the array class in container.h, and makes it use 
std::vector instead.  I also removed the additional functions that 
std::vector does not have, and fixed various things in the code to be 
compatible with std::vector.  If nothing is seriously broken, we can 
soon replace every reference to "array" by "std::vector."

The most immediate problem is as follows: the old array::size() function 
returned an integer, but the std::vector::size() function returns 
size_type, which is unsigned on all platforms that I know of.  In many 
instances, this creates a situation where a signed value is compared to 
an unsigned value.  Not only does this make the compiler spit out a 
bunch of warnings, but it also caused at least one assertion to fail in 
the code.  That assertion is fixed, but if you notice any weird 
behavior, you may wish to uncomment line 165 of libbase/container.h, 
which implements an integer size() function as well.  Over the next few 
days I plan to go through each comparison between an integer variable 
and a size_type variable to get rid of the warnings and make sure 
nothing bad happens.
