Add per-firmware object directory support
Now that we have multiple firmware backends it no longer makes sense
to write object files to the same directory as their source. A better
solution is to write the object files to a per-firmware directory
under a top-level object directory.
The top-level object directory can be specified on the command-line
with the O= variable, e.g. make O=/tmp/obj. If no top-level object
directory is specified an 'obj' directory is created in the top-level
of the Syslinux source repository.
All the existing make targets continue to work as before, however now
they apply to all firmware backends, e.g. 'make installer' will build
the BIOS, 32-bit EFI and 64-bit EFI installers and place them under
$(OBJ)/bios, $(OBJ)/efi32 and $(OBJ)/efi64 respectively.
Note unlike every other bit of Syslinux, the gpxe objects are still
kept in the src directory, e.g. gpxe/src, since gpxe is only required
by the BIOS backend.
It is possible to specify a make target for a specific firmware or
list of firmware with the following syntax,
make [firmware[,firmware]] [target[,target]]
To clean the object directory for just the BIOS firmware type,
'make bios clean'
To build both the 32-bit and 64-bit EFI installers type,
'make efi32 efi64 installer'
Since the Syslinux make infrastructure is now more complex a new file
doc/building.txt has been created to explain how to build Syslinux.
The top-level Makefile now exports some make variables for use in
module Makefiles,
- topdir - the top-level source directory of the Syslinux
repository, e.g. /usr/src/syslinux
- objdir - the top-level object directory for the firmware
backend currently being built, e.g. /obj/syslinux/bios
- SRC - the source directory in the Syslinux repository for the
module currently being built,
e.g. /usr/src/syslinux/com32/libupload
- OBJ - the object directory for the module currently being
built, e.g. /obj/syslinux/bios/com32/libupload
Since we're rewriting the Makefile infrastructure anyway it seemed
like a good idea to add parallel support. By writing subdirectories as
prequisites for make targets the objects in those subdirectories can
be built in parallel.

2. the io.read("*number") is not supported due to the missing buffering in underlying file I/Os. However, the user can read a line using io.read() and convert the string to numbers using the built in pattern matching and number conversion features.
3. io.read(bytes) is supported. However, io.read(0) will not be a valid test for EOF due to the missing I/O buffering. io.read() will return nil if EOF is encountered. This offers an alternative way to handle EOF.

console: Close stdin, stdout, stderr on ldlinux.c32 unload
The location of __file_info[] and ansicon_counter are split between
the core and ldlinux.c32. We can end up calling __ansicon_close (from
fp->oop->close) in the process of reloading ldlinux.c32, and while
ansicon_counter is set to its initialised data value of 0 when
reloading ldlinux.c32, the core is never reloaded, and so
__file_info[] retains its pointers.
What this amounts to is that when ldlinux.c32 tries to call
openconsole() after being reloaded, the core tries to close the
ansicon device (the core still has pointers to __ansicon_close)
despite the ansicon code having no knowledge of ever being opened
(because ansicon_counter was reinitialised).
The most logical way to deal with this is to close stdin, stdout and
stderr when unloading ldlinux.c32.
It also turns out that sys/openconsole.o was present in two Makefile
variables which lead to duplication of code, data, etc. We only need
it present in libcom32min.a and not in the core since the core never
handles opening consoles, at least not now that we've deleted
printf_init() which is safe because we always open a console in
ldlinux.c32 anyway.
