sd_notify is not synchronous, iow. it only waits until the message
reaches the queue not until it is processed by systemd
when the process that sent such a message exits before systemd could
process it, it cannot be associated to the correct pid
so in case of reloading, we send a message with 'MAINPID=<newpid>'
to signal that it will change. if now the old process exits before
systemd knows this, it will not accept the 'READY=1' message from the
child, since it rejects the MAINPID change
since there is no (AFAICS) library interface to check the unit status,
we use 'systemctl is-active <SERVICE_NAME>' to check the state until
it is not 'reloading' anymore.
on newer systemd versions, there is 'sd_notify_barrier' which would
allow us to wait for systemd to have all messages from the current
pid to be processed before acknowledging to the child, but on buster
the systemd version is to old...

it.
Move the FileLogger in ApiConfig into an Arc, so that we can actually
update it and REST using the new one.

so that we can easily get the main PID of the last recently launched
daemon. Will be used to get the control socket of that one for access

Allows to extend the use of that socket in the future, e.g., for log
rotate re-open signaling.
To reflect this we use a more general name, and change the commandos
to a more clear namespace.
Both are actually somewhat a breaking change, but the single real
world issue it should be able to cause is, that one won't be able to
stop task from older daemons, which still use the older abstract
socket name format.

reuse the FileLogger module in append mode.
As it implements write, which is not thread safe (mutable self) and
we use it in a async context we need to serialize access using a
mutex.
Try to use the same format we do in pveproxy, namely the one which is
also used in apache or nginx by default.
Use the response extensions to pass up the userid, if we extract it
from a ticket.
The privileged and unprivileged dameons log both to the same file, to
have a unified view, and avoiding the need to handle more log files.
We avoid extra intra-process locking by reusing the fact that a write
smaller than PIPE_BUF (4k on linux) is atomic for files opened with
the 'O_APPEND' flag. For now the logged request path is not yet
guaranteed to be smaller than that, this will be improved in a future
patch.

using a handlebars instance in ApiConfig, to cache the templates
as long as possible, this is currently ok, as the index template
can only change when the whole package changes
if we split this in the future, we have to trigger a reload of
the daemon on gui package upgrade (so that the template gets reloaded)

The -sys, -tools and -api crate have now been merged into
the proxmx crate directly. Only macro crates are separate
(but still reexported by the proxmox crate in their
designated locations).
When we need to depend on "parts" of the crate later on
we'll just have to use features.
The reason is mostly that these modules had
inter-dependencies which really make them not independent
enough to be their own crates.

Reloadable resources are now 'Reloadable' instead of
'ReexecContinue'.
The struct handling the reload is a 'Reloader', not a
'ReexecStore'.

Add a defines.mk file defining the standard default layout
for installation (PREFIX, DATAROOTDIR, LIBDIR etc.).
Add a $(JSDIR) variable and use env!("JSDIR") in place of
the hardcoded /usr/share/javascript/proxmox-backup path.
Have defines.mk include an *optional* local.mak to override
JSDIR to www/ during local development.
Add `make install` targets and remove debian/install.
Note that service files are now in $libdir/proxmox-backup/
as there's usually no point in starting them from the
command line, so /usr/sbin makes no sense.

We want to run the public server as user www-data. Requests needing
root priviledges needs to be proxied to the proxmox-backup.service, which
now listens to 127.0.0.1:82.
