Summary: Add #pragma section support

Initial Comment:
Hi,

I am currently writing a serial bootloader, and I found 
out that code section assignment is not very flexible 
(well, I changed the linker script, to get my code at the 
end of the code space, but I need a strap @0 as well, 
which I cannot get). I've been looking at the code, and 
I've seen that the memmap mechanism is pretty static, 
and that it need rework in order to perform dynamic 
memory map allocation. 
I am willing to discuss this issue with the person in 
charge for the memmap concept (and possibly code an 
implementation : jhamm[at]insa{dash}lyon(d0t)fr).

This is now possible in SDCC 2.5.1 #1061.
You use the command line option --codeseg MYSEG when 
compiling or pragma codeseg MYSEG inside the source to 
specify the name of the code segment. Then when linking 
you use -Wl-b MYSEG=0x7800 to set the start address of 
this segment.

Hi,

I'm not in charge of the memmap concept, just one of the 
lesser developers. And I think it would be a nice feature if we 
could control the mapping of segments some more.

But my first priority lies with decreasing the number of bugs in 
SDCC.

Greets,
Maarten
