95b3a8c8a8 qapi: More complex uses of QAPI_LIST_APPEND
These cases require a bit more thought to review; in each case, the
code was appending to a list, but not with a FOOList **tail variable.

b7cd9c1e84 clock: Define and use new clock_display_freq()
It's common to want to print a human-readable indication of a clock's
frequency. Provide a utility function in the clock API to return a
string which is a displayable representation of the frequency,
and use it in qdev-monitor.c.

Before:

  (qemu) info qtree
  [...]
  dev: xilinx,zynq_slcr, id ""
    clock-in "ps_clk" freq_hz=3.333333e+07
    mmio 00000000f8000000/0000000000001000

After:

  dev: xilinx,zynq_slcr, id ""
    clock-in "ps_clk" freq_hz=33.3 MHz
    mmio 00000000f8000000/0000000000001000

54aa3de72e qapi: Use QAPI_LIST_PREPEND() where possible
Anywhere we create a list of just one item or by prepending items
(typically because order doesn't matter), we can use
QAPI_LIST_PREPEND().  But places where we must keep the list in order
by appending remain open-coded until later patches.

Note that as a side effect, this also performs a cleanup of two minor
issues in qga/commands-posix.c: the old code was performing
 new = g_malloc0(sizeof(*ret));
which 1) is confusing because you have to verify whether 'new' and
'ret' are variables with the same type, and 2) would conflict with C++
compilation (not an actual problem for this file, but makes
copy-and-paste harder).

5a1ee6077b chardev: do not use machine_init_done
machine_init_done is not the right flag to check when preconfig
is taken into account; for example "./qemu-system-x86_64 -serial
mon:stdio -preconfig" does not print the QEMU monitor header until after
exit_preconfig.  Add back a custom bool for mux character devices.  This
partially undoes commit c7278b4355 ("chardev: introduce chr_machine_done
hook", 2018-03-12), but it keeps the cleaner logic using a function
pointer in ChardevClass.

qdev_machine_creation_done is only setting a flag now.  Extend it to
move more code out of vl.c.  Leave only consistency checks and gdbserver
processing in qemu_machine_creation_done.

gdbserver_start can be moved after qdev_machine_creation_done because
it only does listen on the socket and creates some internal data
structures; it does not send any data (e.g. guest state) over the socket.

38255efffe qdev: Move UUID property to qdev-properties-system.c
Only softmmu code uses DEFINE_PROP_UUID, and it currently depends
on error_set_from_qdev_prop_error().  Move it to
qdev-properties-system.c to get out of our way when refactoring
the qdev property system.

We can eventually move it back to the core property system later,
after removing usage of error_set_from_qdev_prop_error().

837a059516 hw/core/loader.c: Improve reporting of ROM overlap errors
In rom_check_and_register_reset() we report to the user if there is
a "ROM region overlap". This has a couple of problems:
 * the reported information is not very easy to intepret
 * the function just prints the overlap to stderr (and relies on
   its single callsite in vl.c to do an error_report() and exit)
 * only the first overlap encountered is diagnosed

Make this function use error_report() and error_printf() and
report a more user-friendly report with all the overlaps
diagnosed.

Sample old output:

rom: requested regions overlap (rom dtb. free=0x0000000000008000, addr=0x0000000000000000)
qemu-system-aarch64: rom check and register reset failed

Sample new output:

qemu-system-aarch64: Some ROM regions are overlapping
These ROM regions might have been loaded by direct user request or by default.
They could be BIOS/firmware images, a guest kernel, initrd or some other file loaded into guest memory.
Check whether you intended to load all this guest code, and whether it has been built to load to the correct addresses.

The following two regions overlap (in the cpu-memory-0 address space):
  phdr #0: /home/petmay01/linaro/qemu-misc-tests/ldmia-fault.axf (addresses 0x0000000000000000 - 0x0000000000008000)
  dtb (addresses 0x0000000000000000 - 0x0000000000100000)

The following two regions overlap (in the cpu-memory-0 address space):
  phdr #1: /home/petmay01/linaro/qemu-misc-tests/bad-psci-call.axf (addresses 0x0000000040000000 - 0x0000000040000010)
  phdr #0: /home/petmay01/linaro/qemu-misc-tests/bp-test.elf (addresses 0x0000000040000000 - 0x0000000040000020)

5b1de52047 hw/core/loader.c: Track last-seen ROM in rom_check_and_register_reset()
In rom_check_and_register_reset() we detect overlaps by looking at
whether the ROM blob we're currently examining is in the same address
space and starts before the previous ROM blob ends.  (This works
because the ROM list is kept sorted in order by AddressSpace and then
by address.)

Instead of keeping the AddressSpace and last address of the previous ROM
blob in local variables, just keep a pointer to it.

This will allow us to print more useful information when we do detect
an overlap.
