9bd1506d59 Remove function pointers in output, simplify error handling
Remove a bunch of function pointers in the output stage; they are
never changed and don't add any value.  Also make "ofile" a global
variable and let the backend use it directly.

All we ever did with these variables were stashing it in locals and
using them as-is anyway for no benefit.

Also change the global error function, nasm_error() into a true
function which invokes a function pointer internally.  That lets us
use direct calls to it.

9e6747ccac Add copyright headers to the *.c/*.h files in the main directory
Add copyright headers to the *.c/*.h files in the main directory.  For
files where I'm sure enough that we have all the approvals, I have
given them the 2-BSD license, the others have been given the "LGPL for
now" license header.  Most of them can probably be changed after
auditing.

51997d3d44 Introduce likely/unlikely macros, use them in saa.c
Introduce the likely() and unlikely() macros, as used in Linux.
They are compiler-dependent hints that a particular boolean expression
is likely to be true or false, respectively.

Currently only implemented for gcc.

8cc5aa7829 SAA: optimize all power-of-two lengths
We can actually use the shift optimization whenever blk_len ==
SAA_BLKLEN, which will be true for all powers of two.

1cff81e356 SAA: optimize seeks when used on a byte array
In practice, we only ever use the seeking functions on byte arrays
(elem_len == 1).  Optimize for that case, to avoid a general divmod
operation.

1803dedae8 Move all the SAA code out of nasmlib
Move all the SAA code out of nasmlib; it's not used by anything than
nasm itself.  Cleaning out the kitchen sink known as nasmlib is a good
thing, too.
