Peter Maydell 30fd45adb2 Makefile.hw: avoid overly large 'make clean' rm command
Avoid 'make clean' producing an 'rm' command which has a lot
of duplicate 'hw//*.o' arguments, by using $(sort $(dir ..))
rather than $(dir $(sort ..)) so Make's sort function will
remove the duplicates for us. We can also remove the double
'//' safely because $(dir ..) is guaranteed to return a string
ending in '/'.

Paolo Bonzini c353f26194 build: move per-target hw/ objects to nested Makefile.objs
This completes the move to nested Makefiles for virtio and a few
other files that were not part of obj-TARGET-y, but still were
compiled separately for each target.

Paolo Bonzini be1029ec30 build: convert libhw to nested Makefile.objs
After this patch, the libhw* directories will have a hierarchy
that mimics the source tree.  This is useful because we do have
a couple of files there that are in the top source directory.

Stefan Weil 57c83dacfe make: Remove duplicate use of GLIB_CFLAGS
Makefile, Makefile.hw, Makefile.target and libcacard/Makefile
added GLIB_CFLAGS to QEMU_CFLAGS.

Makefile.objs does this, too, and is included by all other
Makefiles, so GLIB_CFLAGS were added twice (reported by malc).

Paolo Bonzini 076d247142 Use vpath directive
The vpath directive has two advantages over the VPATH variable:
1) it allows to skip searching of .o files; 2) the default semantics
are to append to the vpath, so there is no confusion between "VPATH=xyz"
and "VPATH+=xyz".

Since "vpath %.c %.h PATH" is not valid, I'm introducing a wrapper
macro to append one or more directories to the vpath.

Andreas Färber 0e8c9214ba Drop --whole-archive and static libraries
Juan has contributed a cool Makefile infrastructure that enables us to drop
static libraries completely:

Move shared obj-y definitions to Makefile.objs, prefixed {common-,hw-,user-},
and link those object files directly into the executables.

Replace HWLIB by HWDIR, specifying only the directory.

Drop --whole-archive and ARLIBS in Makefiles and configure.

Drop GENERATED_HEADERS dependency in rules.mak, since this rebuilds all
common objects after generating a target-specific header; add dependency
rules to Makefile and Makefile.target instead.

v2:
- Don't try to include /config.mak for user emulators
- Changes to user object paths ("Quickfix for libuser.a drop") were obsoleted
  by "user_only: compile everything with -fpie" (Kirill A. Shutemov)

v3:
- Fix dependency modelling for tools
- Remove comment on GENERATED_HEADERS obsoleted by this patch

Callers must pass ELF machine, byte swapping and symbol LSB clearing

Extract prototypes to a separate file. Move loader.[ch] and elf_ops.h under hw.

Adjust callers. Also use target_phys_addr_t instead of target_ulong for
addresses: loader addresses aren't virtual.

Gerd Hoffmann ee6847d19b qdev: rework device properties.
This patch is a major overhaul of the device properties.  The properties
are saved directly in the device state struct now, the linked list of
property values is gone.

Advantages:
  * We don't have to maintain the list with the property values.
  * The value in the property list and the value actually used by
    the device can't go out of sync any more (used to happen for
    the pci.devfn == -1 case) because there is only one place where
    the value is stored.
  * A record describing the property is required now, you can't set
    random properties any more.

There are bus-specific and device-specific properties.  The former
should be used for properties common to all bus drivers.  Typical
use case is bus addressing, i.e. pci.devfn and i2c.address.

Properties have a PropertyInfo struct attached with name, size and
function pointers to parse and print properties.  A few common property
types have PropertyInfos defined in qdev-properties.c.  Drivers are free
to implement their own very special property parsers if needed.

Properties can have default values.  If unset they are zero-filled.
