fda0e78b23 fix line numbers, again. 
if first function in file was dead code, it was being
discarded along with the file name information for that file.
leave the functions in the master function list longer:
let xfol take the dead code out of the code list,
and let span skip the unreachable functions during output.

8c253bcae5 first attempt at real FFI support. 
in a .6 file, an export line

	//ffi T localfib remotefib remote.so

means the dynamic linker should initialize
localfib, always a pointer, to the address of
remotefib, either text (T) or data (D) after
loading remote.so.

the C compiler will generate an export section
when given the pragmas

	#pragma package fib
	#pragma ffi T localfib remotefib remote.so

needing #pragma package is a bit of a kludge
and hopefully could go away later.

this is just the 6 tool chain support.
other architectures will happen once 6 settles down.

code using this to do FFI is in a later CL.

bd4161fcba FFI step 2: can ask for libc.so.6. 
introduced explicit "data" symbol instead of etext
to mark beginning of data, so that using larger
alignment (i.e. 4MB like GNU loader) doesn't
confuse garbage collector.

split dodata into dodata and dobss in preparation
for putting the dynamic data + headers in the data
segment instead of stuffed at the beginning of the binary.

e5874223ef snapshot: 
- renamed Z -> Int
- made Int ops methods on *Int
- "install" assembly routines dynamically
- replace mulVW functions with mulAddVWW
  of equivalent performance but symmetric functionality
  to divWVW
- implemented scanN

status:
- need mulNN (trivial)
- need division/modulo after which the set of
  elementary operations is complete
- to/from string conversion working
