fab3a6c9de Floating-point warning fixes; fix round-to-overflow
Actually generate the appropriate floating-point warnings, and only
one per assembly, pretty please.

Correct the round-to-overflow condition; as written all numbers with a
positive exponent were considered overflows!

70055964fc Additional uses of bool and enum
Proper use of bool and enum makes code easier to debug.  Do more of
it.  In particular, we really should stomp out any residual uses of
magic constants that aren't enums or, in some cases, even #defines.

6867acc18e Use the compiler-provided booleans if available, otherwise emulate
Both C and C++ have "bool", "true" and "false" in lower case; C
requires <stdbool.h> for this, in C++ it is an inherent type built
into the compiler.  Use those instead of the old macros; emulate with
a simple typedef enum if unavailable.

9d637df6da Rewrite the handling of SAA's to allow random access
SAA's were never intended to allow random access, but several backends
do random or semirandom access via saa_fread() and saa_fwrite()
anyway.  Rewrite the SAA system to allow for efficient random access.

On "label.pl 10000000" this improves performance by a factor of 12.

fe501957c0 Portability fixes
Concentrate compiler dependencies to compiler.h; make sure compiler.h
is included first in every .c file (since some prototypes may depend
on the presence of feature request macros.)

Actually use the conditional inclusion of various functions (totally
broken in previous releases.)

cfdf646e9a Add nasm_zalloc() to nasmlib.c
Add nasm_zalloc(), a wrapper around calloc(), to allocate
zero-initialized memory.  For large allocations, this is often far
more efficient than allocating and zeroing, since the operating system
tends to keep a pool of zero pages around.

87f252aaa5 Make nasm_malloc() et al available from inside ndisasm
Clean up nasmlib to remove functions irrelevant for ndisasm; make
nasm_malloc() etc usable inside ndisasm.

b8af9aa522 Cleaner way to handle MSVC's _snprintf() underscore damage
Some versions of MSVC have snprintf() and vsnprintf() only with a
leading underscore.  Handle that a bit more cleanly.

74cc5e569c Finishing touches on perfect hash tokenizer; actually turn the thing on
Finish the perfect hash tokenizer, and actually enable it.

Move stdscan() et al to a separate file, since it's not needed in any
of the clients of nasmlib other than nasm itself.

Run make alldeps.

0db11e236b Handle "LOCK as REX.R" for MOV CRx; fix warning for invalid 64-bit regs
- MOV gpr,CRx or MOV CRx,gpr can access high control registers with a LOCK
  prefix; handle that in both the assembler and disassembler.
- Get a saner error message when trying to access high resources in
  non-64-bit mode.
