* T5195: move run, cmd, call, rc_cmd helper to vyos.utils.process
* T5195: use read_file and write_file implementation from vyos.utils.file
Changed code automatically using:
find . -type f -not -path '*/\.*' -exec sed -i 's/^from vyos.util import read_file$/from vyos.utils.file import read_file/g' {} +
find . -type f -not -path '*/\.*' -exec sed -i 's/^from vyos.util import write_file$/from vyos.utils.file import write_file/g' {} +
* T5195: move chmod* helpers to vyos.utils.permission
* T5195: use colon_separated_to_dict from vyos.utils.dict
* T5195: move is_systemd_service_* to vyos.utils.process
* T5195: fix boot issues with missing imports
* T5195: move dict_search_* helpers to vyos.utils.dict
* T5195: move network helpers to vyos.utils.network
* T5195: move commit_* helpers to vyos.utils.commit
* T5195: move user I/O helpers to vyos.utils.io

At boot, the util function check_port_availability can return False with
EADDRNOTAVAIL if the interface is not yet up; check explicitly for
address in use.

process_named_running() was introduced in commit 16b2fc8fc4ca ("dns-forwarding:
T2298: fix path to control file") and thus remained more or less unchanged.
Smoketests use process_named_running() heavily and might spawn multiple
processes with the same name but ifferent options (e.g. dhcp6c or dhclient) and
it was yet not possible to properly filter on the "real-deal" like the process
bound to a given interface.
One can now optionally specify a string that is searched inside the command
line argument list of the process.
Example:
>>> process_named_running('dhcp6c', 'veth0')
['/usr/sbin/dhcp6c', '-D', '-k', '/run/dhcp6c/dhcp6c.veth0.sock', '-c',
'/run/dhcp6c/dhcp6c.veth0.conf', '-p', '/run/dhcp6c/dhcp6c.veth0.pid', 'veth0']

>>> process_named_running('dhcp6c', 'veth1')
['/usr/sbin/dhcp6c', '-D', '-k', '/run/dhcp6c/dhcp6c.veth1.sock', '-c',
'/run/dhcp6c/dhcp6c.veth1.conf', '-p', '/run/dhcp6c/dhcp6c.veth1.pid', 'veth1']

Fixed decoding of certificate value returned by vici

This is useful in general, but we will add in this context to replace
the use of 'bytes2HR' in show_openvpn.py with util.bytes_to_human, while
maintaining compatability with original precision=1.

In the OpenVPN site-to-site config we can use IPv6 peers
without IPv4 configurations but "verify()" checks also local and
remote IPv4 addresses that in this case will be empty lists
For example:
set interfaces openvpn vtun2 local-address 2001:db8::1
set interfaces openvpn vtun2 remote-address 2001:db8::2
Check in the commit (v4loAddr == v4remAddr) <= both empty lists
commit
DEBUG: [] == [] or ['2001:db8::2'] == []
So we should also check v4loAddr, v4remAddr, v6loAddr, v6remAddr
are not empty

ipsec: T4594: Rewrite op-mode 'show vpn ipsec sa' to the new format
|
|
We check listen port before commit service if is port available and
not bounded, but when we start openconnect our own port starts be
bounded by "ocserv-main" process and next commit will be fail as
port is already bound
To fix it, extend check if port already bonded and it is not our
self process "ocserv-main"

Convert multiple types of data to types usable in CLI
For example 'vici' returns values in bytestring/bytes and we can
decode them all at once
|
|
It is useful to have both a return code and output of the command
Add a new wrapper "rc_cmd" that returns both
% rc_cmd('uname')
(0, 'Linux')
% rc_cmd('ip link show dev fake')
(1, 'Device "fake" does not exist.')

data = {
'interfaces': {'dummy': {'dum0': {'address': ['192.0.2.17/29']}},

}
dict_search_recursive(data, 'hw_id') will yield both '00:00:00:00:00:01' and
'00:00:00:00:00:02' as generator object.

`print` was removed or replaced to `ValueError`, where possible.

Each wireguard interface requires a unique port for in and out
connections. This commit adds the new `vyos.util` function -
`check_port_availability`, and uses it to be sure that a port
that is planned to be used for wireguard interface is truly
available and not used by any other services (not only other
wireguard interfaces).

Inspired by the comments of https://unix.stackexchange.com/a/435317 use a more
robust approach. A service can be "active" but not "running" (e.g. restarting
with a configuration error). We can now test if a systemd unit is "activated"
and if it is "running" at all.
>>> from vyos.util import is_systemd_service_active
>>> from vyos.util import is_systemd_service_running
>>> is_systemd_service_active('ssh')
True
>>> is_systemd_service_running('sshd')
False
>>> is_systemd_service_running('ssh')
True
|
|
Test is a specified systemd service is actually running.
Returns True if service is running, false otherwise.

When waiting for processes that don't take long,
we need add an inotify watcher _before_ starting that process.
The pre-hook arguments allows the user to pass a () -> () anonymous function
to be called before adding a watch.
|

|
Also adds check for the charon socket instead of an arbitrary sleep()
