The ADC is part of NPCM7XX Module. Its behavior is controled by the
ADC_CON register. It converts one of the eight analog inputs into a
digital input and stores it in the ADC_DATA register when enabled.
Users can alter input value by using qom-set QMP command.

Prior to this patch, the fuzzer found inputs to map PCI device BARs and
enable the device. While it is nice that the fuzzer can do this, it
added significant overhead, since the fuzzer needs to map all the
BARs (regenerating the memory topology), at the start of each input.
With this patch, we do this once, before fuzzing, mitigating some of
this overhead.

qobject_to_json() and qobject_to_json_pretty() build a GString, then
covert it to QString. Just one of the callers actually needs a
QString: qemu_rbd_parse_filename(). A few others need a string they
can modify: qmp_send_response(), qga's send_response(), to_json_str(),
and qmp_fd_vsend_fds(). The remainder just need a string.
Change qobject_to_json() and qobject_to_json_pretty() to return the
GString.
qemu_rbd_parse_filename() now has to convert to QString. All others
save a QString temporary. to_json_str() actually becomes a bit
simpler, because GString provides more convenient modification
functions.

In using the address_space_translate_internal API, address_space_cache_init
forgot one piece of advice that can be found in the code for
address_space_translate_internal:
/* MMIO registers can be expected to perform full-width accesses based only
* on their address, without considering adjacent registers that could
* decode to completely different MemoryRegions. When such registers
* exist (e.g. I/O ports 0xcf8 and 0xcf9 on most PC chipsets), MMIO
* regions overlap wildly. For this reason we cannot clamp the accesses
* here.
*
* If the length is small (as is the case for address_space_ldl/stl),
* everything works fine. If the incoming length is large, however,
* the caller really has to do the clamping through memory_access_size.
*/
address_space_cache_init is exactly one such case where "the incoming length
is large", therefore we need to clamp the resulting length---not to
memory_access_size though, since we are not doing an access yet, but to
the size of the resulting section. This ensures that subsequent accesses
to the cached MemoryRegionSection will be in range.
With this patch, the enclosed testcase notices that the used ring does
not fit into the MSI-X table and prints a "qemu-system-x86_64: Cannot map used"
error.

The generic fuzzer can find double-fetch bugs. However:
* We currently have no good way of producing qemu-system reproducers for
double-fetch bugs. Even if we can get developers to run the binary-blob
reproducers with the qemu-fuzz builds, we currently don't have a minimizer for
these reproducers, so they are usually not easy to follow.
* Often times the fuzzer will provide a reproducer containing a
double-fetch for a bug that can be reproduced without double-fetching.
Until we find a way to build nice double-fetch reproducers that
developers are willing to look at, lets tell OSS-Fuzz to avoid
double-fetches.

However, when multiple sections are defined in the same "INSERT AFTER",
they are added in a reversed order, compared to BFD's LD.
This patch makes fork_fuzz.ld generic enough to work with both linkers.
Each section now has its own "INSERT AFTER" keyword, so proper ordering is
defined between the sections added.
