Added #includes for the headers that these headers depend upon.
I'm still not convinced of the wisdom of having #includes inside
headers. Tracking down the location of a declaration by using
preprocessed source files is bad enough when nested #include
is forbidden.

More cleanup of the bytecode stuff; in particular, add a `MB_' prefix
to most names.
bytecode/*:
- Prefix all names defined in header files with `MB_'
(except for `TRUE', `FALSE', `DEBUGGING', and `XXXdebug').
- Add macros `MB_new', `MB_new_array', and `MB_resize_array',
and use those instead of using `MB_malloc' and `MB_resize'
(formerly `mem_malloc' and `mem_resize') or malloc() and realloc()
directly. Uncomment the definition of MB_strdup() now that it
calls MB_malloc().
- Delete the definitions of `uchar', `uint', `ushort', `ulong'
(just spell them out, its clearer and more portable that way).
- Fix the indentation in a few places I missed on my previous pass.
- Add a `README' file.

A cleanup of the bytecode stuff.
bytecode/*:
Various changes to make it conform to our C coding standard.
In particular:
- fix indentation and layout, particularly of switch
statements;
- use `#include "..."' rather than `#include <...>'
for user-defined header files
bytecode/Mmakefile:
Avoid the use of `$^' in hard-coded rules, since it is
not portable to non-GNU makes (many makes only allow the
use of variables such as $*, $^, etc. in suffix rules),
and since it is easy to avoid.
Also add an XXX comment, since the header dependency handling
is done twice.
bytecode/bytecode.c:
s/BIG_ENDING/MR_BIG_ENDIAN/ and s/LITTLE_ENDING/MR_LITTLE_ENDIAN/,
to match my recent change to runtime/conf.h.in.
In fact every identifier in the bytecode directory ought to be
prefixed with `MB_', but I haven't done that in this change.

A number of changes:
- Changes to support portable numeric constants in the
bytecode file.
- read_int() now returns a Mercury `Integer', which is platform
dependent. However it actually reads a portable, 64-bit,
big-endian, 2's complement integer from the bytecode stream.
- read_float() now returns a Mercury `Float', which is platform
dependent.
- Comment-style changed to agree with C coding standard.
- malloc and realloc are now used instead of mem_malloc and
mem_realloc. Need to look at memory-management in a lot
more depth when the bytecode interpreter starts linking
in Mercury shared objects.
- Removed Bytecode-doc since it's now an HTML file in
the developer documentation directory of the Mercury web pages.
- Removed the Makefile since we're now using an Mmakefile.
