Instead of having unchecked fwrite() calls, introduce nasm_write()
which does error checking (and fatal errors if the write fails).

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.

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.

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.
