Unfortunately since we didn't manage to get the script changes that

Our current QAPI doc-comment markup allows section headers (introduced
with a leading '=' or '==') anywhere in a free-form documentation
comment. This works for Texinfo because the generator simply prints a
Texinfo section command at that point in the output stream. For rST
generation, since we're assembling a tree of docutils nodes, this is
awkward because a new section implies starting a new section node at
the top level of the tree and generating text into there.
Make section headers start a new free-form documentation block, so the
future rST document generator doesn't have to look at every line in
free-form blocks and handle headings in odd places.
This change makes no difference to the generated Texinfo.

There are several problems here that can result in soft lockup,
depending on exactly where an interrupt or exception is delivered:
Include BIMM_FLAG in IFLAGS_TB_MASK, since it needs to follow D_FLAG.
Ensure that iflags is 0 when entering an interrupt/exception handler.
Add mb_cpu_synchronize_from_tb to restore iflags from tb->flags.
The change to t_sync_flags is cosmetic, but makes the code clearer.
This fixes the reported regression in acceptance/replay_kernel.py.

If nettle is disabled and gcrypt enabled, the compiler and linker flags
needed for gcrypt are not passed.
Gnutls was also not added as a dependancy when gcrypt is enabled.
Attempting to add the library dependencies at the same time as the
source dependencies is error prone, as there are alot of different
rules for picking which sources to use, and some of the source files
use code level conditionals intead. It is thus clearer to add the
library dependencies separately.

Now that we can use all our QEMU test containers in the gitlab-CI, we can
easily add some jobs that test cross-compilation for various architectures.
There is just only small ugliness: Since the shared runners on gitlab.com

(--disable-user and --disable-system), and exclude some additional targets,
to avoid that the jobs are running too long and hitting the timeout of 1 h.

remove the qemu_notify_event() stub now.

Target definitions of btrfs ioctls in 'syscall_defs.h' use
the value BTRFS_IOCTL_MAGIC that is defined header 'btrfs.h'.
This header is not available in kernel versions before 3.9.
For that reason, these target ioctl definitions should be
enwrapped in an #ifdef directive to check whether the 'btrfs.h'
header is available as to not cause build errors on older
Linux systems.

info->brk was erroneously set to the end of highest addressed
writable segment which could result it in overlapping the executable.
As per load_elf_binary in fs/binfmt_elf.c in Linux, it should be
set to end of highest addressed segment.

This patch introduces functionality for following time64 syscalls:
*ppoll_time64
This is a year 2038 safe variant of:
int poll(struct pollfd *fds, nfds_t nfds, int timeout)
-- wait for some event on a file descriptor --
man page: https://man7.org/linux/man-pages/man2/ppoll.2.html
*pselect6_time64
This is a year 2038 safe variant of:
int pselect6(int nfds, fd_set *readfds, fd_set *writefds,
fd_set *exceptfds, const struct timespec *timeout,
const sigset_t *sigmask);
-- synchronous I/O multiplexing --
man page: https://man7.org/linux/man-pages/man2/pselect6.2.html
Implementation notes:
Year 2038 safe syscalls in this patch were implemented
with the same code as their regular variants (ppoll() and pselect()).
This code was moved to new functions ('do_ppoll()' and 'do_pselect6()')
that take a 'bool time64' from which a right 'struct timespec' converting
function is called.
(target_to_host/host_to_target_timespec() for regular and
target_to_host/host_to_target_timespec64() for time64 variants)
