During migration, there are several places to iterate on
savevm.handlers. And on each iteration, we need to check its ops and
related callbacks before invoke it.
Generally, ops is the first element to check, and it is only necessary
to check it once.
This patch clean all the related part in savevm.c to check ops only once
in those iterations.

The ordering of events that are emitted during the rmdir
test have changed with kernel >= 5.3. Semantically both
new & old orderings are correct, so we must be able to
cope with either.
To cope with this, when we see an unexpected event, we
push it back onto the queue and look and the subsequent
event to see if that matches instead.

Xtensa binaries built for call0 ABI don't rotate register window on
function calls and returns. Invocation of signal handlers from the
kernel is therefore different in windowed and call0 ABIs.
There's currently no way to determine xtensa ELF binary ABI from the
binary itself. Add handler for the -xtensa-abi-call0 command line
parameter/QEMU_XTENSA_ABI_CALL0 envitonment variable to the qemu-user
and record ABI choice. Use it to initialize PS.WOE in xtensa_cpu_reset.
Check PS.WOE in setup_rt_frame to determine how a signal should be
delivered.

This is needed to support debugging PIE ELF binaries running under QEMU
user mode. Currently, `code_offset` and `data_offset` remain unset for
all ELF binaries, so GDB is unable to correctly locate the position of
the binary's text and data.
The fields `code_offset`, and `data_offset` were originally added way
back in 2006 to support debugging of bFMT executables (978efd6aac),
and support was just never added for ELF. Since non-PIE binaries are
loaded at exactly the address specified in the binary, GDB does not need
to relocate any symbols, so the buggy behavior is not normally observed.

Turn the scalar macro into a functional macro. Move the creation
of the cpu up a bit within main() so that we can pass it to the
invocation of MAX_RESERVED_VA. Delay the validation of the -R
parameter until MAX_RESERVED_VA is computed.
So far no changes to any of the MAX_RESERVED_VA macros to actually
use the cpu in any way, but ARM will need it.

The LinuxInitrd.test_with_2gib_file_should_work_with_linux_v4_16 test,
from tests/acceptance/linux_initrd.py, is currently failing to fetch
the "vmlinuz" file. The reason for the failure is that the Fedora
project retires older versions from the "dl.fedoraproject.org" URL,
and keeps them in "archives.fedoraproject.org". As an added note,
that test uses a Fedora 28 image, because of the specific Linux kernel
version requirements of the test.
For the sake of stability, let's use URLs from the archived and
supposedely ever stable URLs. The good news is that the currently
supported versions are also hosted on the later. This change limits
itself to change the URLs, while keeping the fetched files the same
(as can be evidenced by the unchanged hashes).
Documentation and the "vm tests" fedora definition were also updated.

Per https://ccache.dev/manual/latest.html:
By default, ccache tries to give as few false cache hits as
possible. However, in certain situations it’s possible that
you know things that ccache can’t take for granted.
[The CCACHE_SLOPINESS environment variable] makes it possible
to tell ccache to relax some checks in order to increase the
hit rate.
We can relax the ctime/mtime header checks:
- include_file_ctime
By default, ccache also will not cache a file if it
includes a header whose ctime is too new. This option
disables that check.
- include_file_mtime
By default, ccache will not cache a file if it includes
a header whose mtime is too new. This option disables
that check.
We also add a call to clear the cache statistics before running
the build, and display them when the build finishes.
