Certain modules directly make BIOS calls or call library functions that
will not be ported from BIOS (like syslinux_shuffle_boot_rm()).
It appears dir.c32 was long-forgotten for the Makefile

It's useful to be able to enable (and disable) debug code at runtime,
particularly for allowing users that are unable to build their own
Syslinux releases the chance to provide useful debugging output.
For example, say a user reports trouble with their PXE stack but doesn't
have a development environment setup to turn on the debug code
themselves. With this change you can simply request that they do,
debug.c32 -e pxe_call unload_pxe open_file
to enable the debug in those functions. By only turning on code in
specific functions we reduce the chance of disrupting the buggy
behaviour and improve the signal to noise ratio for print statements.
To disable debug code use the -d flag,
debug.c32 -d pxe_call
To use this new feature simply do,
if (syslinux_debug_enabled) {
debug1();
debug2();
....
}
from within the function you wish to add debug code. Note that this
feature is not limited to print statements - you can put any code within
the conditional, such as verifying a checksum or checking for memory
leaks.
The plan is to leave the dynamic debug code built in for all prereleases
and to turn it off for final releases.
People may still want to build with all dprintf() statements enabled,
and so a new symbol, DYNAMIC_DEBUG, was introduced rather than
repurposing the old DEBUG, DEBUG_STDIO and DEBUG_PORT symbols.

When using a Kontron ETX board, it's possible to initialize and start
the watchdog during syslinux booting.
This allow protecting a boot sequence with a defined timeout.
Bootloader is starting, engage the watchdog and then start a default
entry (typically a Linux image).
If the loaded OS, feed or reinitalize the watchdog, nothing occurs
unless the system will reboot

Modules were linking against com32/gpllib/libcom32gpl.c32 even when
NOGPL was set, so remove it from various modules Makefiles and use
$(C_LIBS) in mk/elf.mk which already has the conditional-magic for
$(GPLLIB).
Also, the object files in com32/gpllib/ are not distributed in the
release tarballs, which means that if a user does a 'make netinstall'
they hit the following install error,
install: cannot stat `com32/gpllib/*.c32': No such file or directory
Add a $(INSTALLABLE_MODULES) variable to separate the list of build
and install modules.

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.

This extends commit 4678fd92a21e ("elflink: fix dependency problem in
cmenu/Makefile") and basically reverts commit fb543aa635ff ("com32:
Per-object file LDFLAGS"). By using the --as-needed ld argument we can
specify all the required shared libraries for a directory, even if not
all of the libraries are needed by every .c32 file. --as-needed takes
care of only creating DT_NEEDED entries for the shared libraries that
are actually required to resolve undefined symbols in a given module.
Furthermore, by using $(LIBS) we create a dependency between .c32
files and their shared libraries, which allows multiple make jobs to
run in parallel.

Some object files need to link against the ELF libraries. Allow them
to be specified with the following syntax in the Makefiles,
LDFLAGS_$(object_file) = $(LIBS)
By adding libraries in this way DT_NEEDED entries are created in the
ELF modules and the required library dependencies are automatically
loaded before running the module.

com32/elflink/modules was originally created to house ELF modules and
keep them separate from the COM32 modules as the elflink branch was
being developed. However, this has inadvertently created a maintenance
nightmare because code was copied from elsewhere in the tree into
com32/elflink/modules, resulting in duplication. Bug fixes have been
going into the original code but have not been merged onto the elflink
branch, leaving the duplicate code in com32/elflink/modules buggy.
So let's delete this directory. There really is no reason to keep ELF
and COM32 modules separate because there's no reason to need both
COM32 and ELF modules to coexist. ELF is a far superior object file
format and all modules are not emitted as ELF objects.
Now that we're outputting ELF modules we can use dynamic memory
instead of the cs_bounce bounce buffer.
This commit requires a certain amount of shuffling for some
files. quicksort.c isn't a module and belongs as part of the util
library. cli.h belongs in com32/include so that other modules can make
use of the cli code in ldlinux.c32.
All libraries are now ELF shared libraries which are only loaded to
fixup unresolved symbols for executable modules and renamed from *.a
to *.c32. This reduces the runtime memory footprint because libraries
are only loaded when needed and because every executable no longer
gets its own copy of code/data (as it would if linking with a static
library). Also, remove MINLIBOBJS from libcom32.c32 because it is
already part of libcom32min.a and we don't want to have any duplicate
symbols between the core (which links with libcom32min.a) and
libcom32.c32.
Welcome to the New World Order of ELF modules!

Move the MCONFIG files into a mk/ directory and give them more
descriptive names.
This is purely a cosmetic change to make the 'include' directives a
bit more coherent by making it obvious exactly which MCONFIG file
we're including. For example, in com32/lua/src/Makefile we exchange
the line,
include ../../MCONFIG
for the much more comprehensible,
include $(MAKEDIR)/com32.mk

Impact: driveinfo structure change, new disk.c32 module
Adapt driveinfo structure to store both legacy and EDD parameters. Change utility
functions to use EDD when available (C/H/S being a fallback).
Add a new disk.c32 module to test the disk library. It will print information
(geometry) about every detected drive.
Misc.: refactoring, set ES:DI to 0:0 when querying legacy C/H/S
