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.

vl: move all generic initialization out of vl.c

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.

Only softmmu code uses DEFINE_PROP_UUID, and it currently depends

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().

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)

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.
