Basically a checkpoint. 

Fri Jan  8 15:47:53 1993  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)

	* bfd.c (struct _bfd): Added ecoff_tdata to tdata union.
	* targets.c (enum target_flavour): Added bfd_target_ecoff_flavour.
	* coff-msym.c: Use DEFUN for function definitons.
	* coff-mips.c: Added code to read and print symbols, and to find
	line numbers.

* coffcode.h: Moved many generic functions into coffgen.c. Moved
swapping functions into coffswap.h for ECOFF use. Moved
relocation functions, only used by h8300 and z8k, into reloc16.c.

FUNCTION
The bfd_get_size function
SYNOPSIS
long bfd_get_size(bfd *);
DESCRIPTION
Return file size (as read from file system) for the file
associated with a bfd.
Note that the initial motivation for, and use of, this routine is not
so we can get the exact size of the object the bfd applies to, since
that might not be generally possible (archive members for example?).
Although it would be ideal if someone could eventually modify
it so that such results were guaranteed.
Instead, we want to ask questions like "is this NNN byte sized
object I'm about to try read from file offset YYY reasonable?"
As as example of where we might want to do this, some object formats
use string tables for which the first sizeof(long) bytes of the table
contain the size of the table itself, including the size bytes.
If an application tries to read what it thinks is one of these
string tables, without some way to validate the size, and for
some reason the size is wrong (byte swapping error, wrong location
for the string table, etc), the only clue is likely to be a read
error when it tries to read the table, or a "virtual memory
exhausted" error when it tries to allocated 15 bazillon bytes
of space for the 15 bazillon byte table it is about to read.
This function at least allows us to answer the quesion, "is the
size reasonable?".
