This reverts commit
b6522938327141235b97ab38e40c6c4512587373.
Kevin Wolf NAKed this patch, because:
'file' is a required member (defined in BlockdevOptionsGenericFormat),
removing it makes the example invalid. 'data-file' is only an additional
optional member to be used for external data files (i.e. when the guest
data is kept separate from the metadata in the .qcow2 file).
However, it had already been merged then. Revert.

tcg/ppc: Optimize 26-bit jumps
PowerPC64 processors handle direct branches better than indirect
ones, resulting in less stalled cycles and branch misses.
However, PPC's tb_target_set_jmp_target() was only using direct
branches for 16-bit jumps, while PowerPC64's unconditional branch
instructions are able to handle displacements of up to 26 bits.
To take advantage of this, now jumps whose displacements fit in
between 17 and 26 bits are also converted to direct branches.

docs: Update TPM documentation for usage of a TPM 2
Update the TPM documentation for usage of a TPM 2 rather than a TPM 1.2.
Adjust the command lines and expected outputs inside the VM accordingly.
Update the command line to start a TPM 2 with swtpm.

Use g_new() & friends where that makes obvious sense
g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This commit only touches allocations with size arguments of the form
sizeof(T).

Drop superfluous conditionals around g_free()
There is no need to guard g_free(P) with if (P): g_free(NULL) is safe.

block/qcow2-bitmap: Add missing cast to silent GCC error
Commit
d1258dd0c8 ("qcow2: autoloading dirty bitmaps") added the
set_readonly_helper() GFunc handler, correctly casting the gpointer
user_data in both the g_slist_foreach() caller and the handler.
Few commits later (commit
1b6b0562db), the handler is reused in
qcow2_reopen_bitmaps_rw() but missing the gpointer cast, resulting
in the following error when using Homebrew GCC 12.2.0:
