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.
