Instead of manually creating the BlockdevCreateOptions object, use a
visitor to parse the given options into the QAPI object.
This involves translation from the old command line syntax to the syntax
mandated by the QAPI schema. Option names are still checked against
qcow2_create_opts, so only the old option names are allowed on the
command line, even if they are translated in qcow2_create().
In contrast, new option values are optionally recognised besides the old
values: 'compat' accepts 'v2'/'v3' as an alias for '0.10'/'1.1', and
'encrypt.format' accepts 'qcow' as an alias for 'aes' now.

This function deletes a snapshot from disk, removing its entry from
the snapshot table, freeing its L1 table and decreasing the refcounts
of all clusters.
The L1 table offset and size are however not validated. If we use

more, so we should return an error instead.

This function checks that the offset and size of a table are valid.
While the offset checks are fine, the size check is too generic, since
it only verifies that the total size in bytes fits in a 64-bit
integer. In practice all tables used in qcow2 have much smaller size
limits, so the size needs to be checked again for each table using its
actual limit.
This patch generalizes this function by allowing the caller to specify
the maximum size for that table. In addition to that it allows passing
an Error variable.
The function is also renamed and made public since we're going to use
it in other parts of the code.

The previous commit improved compile time by including less of the

possible.
It's possible everywhere, except:
* monitor.c needs qmp-command.h to get qmp_init_marshal()
* monitor.c, ui/vnc.c and the generated qapi-event-FOO.c need
qapi-event.h to get enum QAPIEvent

The include directive permits modular QAPI schemata, but the generated
code is monolithic all the same. To permit generating modular code,
the front end needs to pass more information on inclusions to the back
ends. The commit before last added the necessary information to the
parse tree. This commit adds it to the intermediate representation
and its QAPISchemaVisitor. A later commit will use this to to
generate modular code.
New entity QAPISchemaInclude represents inclusions. Call new visitor
method visit_include() for it, so visitors can see the sub-modules a
module includes.
Note that unlike other entities, QAPISchemaInclude has no name, and is
therefore not added to entity_dict.
New QAPISchemaEntity attribute @module names the entity's source file.
Call new visitor method visit_module() when it changes during a visit,
so visitors can keep track of the module being visited.

Commit 92b540dac9 introduce a counter to handle the timeouts in a
better way. But in case ccnt reaches 512, the current read character is
ignored - and if that character is part of the string that we are looking
for, the test fails to match the string.
Almost all of the tests look for a string within the first 512 bytes of
firmware output, so the problem never triggered there. But the hppa test
that has been added recently looks for a longer string at the very end of
a long output, thus there's a chance that we miss a character there so
that the test fails unexpectedly. Fix it by *not* reading and dropping a
character if the counter reaches 512.

The ref405ep machine has a memory-mapped m48t59 device, so
we can run the m48t59 test on this machine, too.

Stop using the functions that require global_qtest here and pass
around the QTestState instead (global_qtest should finally get
removed since this causes problems with tests running in parallel).

The m48t59 test has been disabled in commit baeddded5f
("sparc: disable qtest in make check"), likely due to some timing issues
in the bcd_check_time tests which might fail if it gets interrupted for
too long. It should be OK to re-enable this test if we make sure that we
do not run it on timing-sensitive machines, thus it should be OK if we only
run it in the g_test_slow() mode.
Additionally, there are two other issues:
First, the test can not run so easily on sparc64 anymore, since commit
f3b18f35a2 ("sun4u: switch m48t59 NVRAM to MMIO access")
moved the m48t59 device to the ebus instead, and for this you first
have to set up the corresponding PCI device (which is currently not
possible from within the m48t59 test). So we can only re-enable this
test on sparc, but not the sparc64 target.
Second, the fuzzing test is executed before the bcd-check-time test
(due to the naming of the tests), without having the base address set
up properly, so the fuzzing test does not really check anything at all.
Fix it by setting up the base address from the main function already
and by moving the qtest_start() to the tests themselves, so that each
test starts with a clean environment (since after the fuzzing, the clock
is unusable for the bcd-check-time test).
