We search the dependency list anyway (ouch...) so we might as well
use that instead of keeping track of a tail pointer.

Always return found_path as a constant string. We end up making an
internal copy of it anyway to put in the fullpath hash, so there is no
reason to make a duplicate of it.

We have been doing a pathname search every time we encounter a file,
which means every file in every pass. Instead, put the pathnames
found in a hash table.

A number of fairly common operations are invoked way too many times,
especially when using incbin. Drastically reduce the number of system
calls that need to be executed, and use memory mapping to reduce
unnecessary double buffering.
We could improve this further by leaving files open once used;
however, that might run into file count problems on some systems.
Still unclear is why we seem to invoke nasm_file_size() twice per pass
for incbin.

The ordering of the macro sets ended up changing due to the recent
file reorganization. Instead of forcing the order again, handle
multiple macro sets (rather than just two) in a coherent manner.
macros/macros.pl could use a cleanup of duplicated code, however.

Make the source code easier to understand and keep track of by
organizing it into subdirectories depending on the function.
