Summary:  Extend pgmspace.h with pgm_read_long()

Original Submission:  The header file pgmspace.h

/* $Id: pgmspace.h,v 1.16.2.2 2003/09/18 18:41:17 troth Exp $ */

does not support pgm_read_long(). I suggest to extend this
file by applying the attached patch.

I'm all right with that! Great idea! Wish I'd thought of it... :-)

I've updated the patch changing long to dword.

In the end, I think it would just be better to drop the word notation and just 
use these:

pgm_read_uint8()
pgm_read_uint16()
pgm_read_uint32()

There's absolutely no ambiguity with those names. Alas, this can't be done in 
the 1.0 branch since it would break compatibility. Although, we could have the 
old names as aliases for the proposed *_uint* names and mark the old as 
deprecated. That's a separate patch from this one though.

Should the naming of the macros be consistent? Right now, we have:
pgm_read_byte()
pgm_read_word()

Wouldn't the next logical name be: pgm_read_dword()?

Not pgm_read_long()? Since the meaning of "long" in C can change (or will 
change) with the use of -mint8.

There's a few copy/paste errors in the originally submitted patch.

Also, the original patch didn't include any context information. For future 
reference, please try to submit patches generated using diff's "-u" option. 
This makes the patch easier to read (most of the time) and allows the patch 
program to apply the patch to a file that may have been modified since the diff 
was generated.

I've attached an updated patch which fixes the copy/paste errors I noticed.

I don't have any objections to applying this patch to HEAD or 1.0 since it is a 
simple extension of the API.

I'll try to get it into 1.0.4, but I need to do a better review of the inline 
asm first. So far, from a quick review it looks ok to me.
