qtest: introduce qtest_init_ext

Merge qtest_init_with_env_and_capabilities() and qtest_init_with_env()
into one qtest_init_ext().

Reasons:

1. qtest_init_with_env() is just wrong: it gets do_connect parameter
but always pass true to qtest_init_with_env_and_capabilities().
Happily, all qtest_init_with_env() callers pass true as well.

2. qtest_init_with_env() is not used outside of libqtest.c, so no
reason to keep it as public function

3. and in libqtest.c it's used not often, so no problem to use
more generic function instead.

Migration capabilities are set in multiple '.start_hook'
functions for various tests. Instead, consolidate setting
capabilities in 'migrate_start_set_capabilities()' function
which is called from the 'migrate_start()' function.
While simplifying the capabilities setting, it helps
to declutter the qtest sources.

qapi: Move include/qapi/qmp/ to include/qobject/

The general expectation is that header files should follow the same
file/path naming scheme as the corresponding source file. There are
various historical exceptions to this practice in QEMU, with one of
the most notable being the include/qapi/qmp/ directory. Most of the
headers there correspond to source files in qobject/.

This patch corrects most of that inconsistency by creating
include/qobject/ and moving the headers for qobject/ there.

This also fixes MAINTAINERS for include/qapi/qmp/dispatch.h:
scripts/get_maintainer.pl now reports "QAPI" instead of "No
maintainers found".

tests/qtest/migration: Move common test code

The migration tests have a set of core infrastructure routines. These
are functions that are called by (almost) all tests and centralize the
common operations of: starting migration on both sides, waiting for
guests to boot, performing guest initialization and teardown, guest
memory validation, etc.

Move this basic framework code (and a few static helpers) into a
separate file. Leave only individual test functions (and their own
static helpers) in migration-test.c.
