Refactor qemu_xkeymap_mapping_table() to have a single exit point,
so we can easily free the memory allocated by XGetAtomName().
This fixes when running a binary configured with --enable-sanitizers:
Direct leak of 22 byte(s) in 1 object(s) allocated from:

#1 0x7fa4d9dc08aa in XGetAtomName (/lib64/libX11.so.6+0x2a8aa)

When TCG is enabled, the accel/tcg/ include path is added to the
project global include search list. This accel/tcg/ directory
contains a header named "internal.h" which, while intented to
be internal to accel/tcg/, is accessible by all files compiled
when TCG is enabled. This might lead to problem with other
directories using the same "internal.h" header name:
$ git ls-files | fgrep /internal.h
accel/tcg/internal.h
include/hw/ide/internal.h
target/hexagon/internal.h
target/mips/internal.h
target/ppc/internal.h
target/s390x/internal.h
As we don't need to expose accel/tcg/ internals to the rest of
the code base, simplify by removing it from the include search
list, and include the accel/tcg/ public headers relative to the
project root search path (which is already in the generic include
search path).

This is a small rewrite to address some minor style nits.
Don't compare against the empty list to check for the empty condition, and
move the normalization forward to unify the check on the now-normalized
structure.
With the check unified, the local nested function isn't needed anymore
and can be brought down into the normal flow of the function. With the
nesting level changed, shuffle the error strings around a bit to get
them to fit in 79 columns.
Note: although ifcond is typed as Sequence[str] elsewhere, we *know* that
the parser will produce real, bona-fide lists. It's okay to check
isinstance(ifcond, list) here.

Casts are instructions to the type checker only, they aren't "safe" and
should probably be avoided in general. In this case, when we perform
type checking on a nested structure, the type of each field does not
"stick".
(See PEP 647 for an example of "type narrowing" that does "stick".
It is available in Python 3.10, so we can't use it yet.)
We don't need to assert that something is a str if we've already checked
or asserted that it is -- use a cast instead for these cases.

For a successful conversion of an image, we must make sure that its
content doesn't change during the conversion.
A special case of this is using the same image file both as the source
and as the destination. If both input and output format are raw, the
operation would just be useless work, with other formats it is a sure
way to destroy the image. This will now fail because the image file
can't be opened a second time for the output when opening it for the
input has already acquired file locks to unshare BLK_PERM_WRITE.
Nevertheless, if there is some reason in a special case why it is
actually okay to allow writes to the image while it is being converted,
-U can still be used to force sharing all permissions.
Note that for most image formats, BLK_PERM_WRITE would already be
unshared by the format driver, so this only really makes a difference
for raw source images (but any output format).

Normally, blk_new_open() just shares all permissions. This was fine
originally when permissions only protected against uses in the same
process because no other part of the code would actually get to access
the block nodes opened with blk_new_open(). However, since we use it for
file locking now, unsharing permissions becomes desirable.

We don't have bdrv_replace_child(), so it's time for
bdrv_replace_child_safe() to take its place.

Old interfaces dropped, nobody directly calls
bdrv_child_set_perm_abort() and bdrv_child_set_perm_commit(), so we can
use personal state structure for the action and stop exploiting
BdrvChild structure. Also, drop "_safe" suffix which is redundant now.
