This uses rbnacl-sodium which bundle an old version of libsodium that
can not be compiled with gcc 12. This is an optional dependency to
support ed25519 ssh keys, but we the slapos version of gitlab does not
use ssh, only https, so we don't actually need to install this.

To prevent linking with system libtirpc if the corresponding system
-dev package is installed

We were using --without-ncurses but this does not prevent the build
from using system package when ncurses-dev system package is installed.

if only bison exists in PATH, we will get an error:
/path/to/bison: m4 subprocess failed: No such file or directory

This was building against system library when ncurses-dev system
package is installed

This concerns a case of resiliency in Theia: when a resilient Theia
requests multiple import clones (by default only one is requested),
e.g. when theia0 (export) has two import clones theia1 and theia2.

Each clone requests a frontend for their theia service, which allows
the Theia editor of the clone to be accessed without doing a takeover.

Before this, all the import clones would request a frontend with the
same name. This meant that only one frontend was allocated and might
randomly redirect to one of the backup clones.

We had to introduce a web page to bootstrap the web version of devtools
because since https://bugs.chromium.org/p/chromium/issues/detail?id=1232509
chrome debugger port no longer serve such a page via HTTP.

The URL also changed, /serve_file/@{version_hash}. pattern is no longer
used, both the devtools and the websocket endpoint are in /devtools

The test was made a bit more complete by actually making requests and
trying to connect to websocket endpoints.

Some problems were found with incognito and block-new-web-contents
options:
 - they are boolean type, but the software parameter serialisation is
 XML, which as of today does not support boolean types. This is left
 TODO for now
 - When both --incognito and --block-new-web-contents are true, the
 command line flag was --incognito--block-new-web-contents, which is
 unknown and was ignored. Some minmal changes are included to fix this.

By reusing recently added "split TAP" infrastructure we can adjust dnsmasq
configuration to provide unique IPv6 to each RU.

- ru_mac_addr becomes per-RU setting and without default. We talked with Lu, and
  since now all Lopcomm units are shipped from the factory with unique MAC, it
  both does not make sense to provide the default, and we can rely on all units
  to have different MACs and configure DHCP replies based on that.

- No need to provide /64 network to every RU. We cannot actually do that anyway
  because normally SlapOS provides /71 address range for its slaptap. In the
  new configuration everything works with smaller networks just ok.

Those options are not needed, because we need to only provide IPv6 address to
RU, and also they are not very meaningful: in the current form we tell RU that
DNS addresses sit at RU.addr+1 and RU.addr+2, i.e. in the IP range we give to
RU and also at the addresses where no DNS server is actually running.

It was probably a thinko to add those options initially.

Core Network and ENB use dnsmasq for completely different purposes:

- core network uses it to provide DNS server, while
- enb uses dnsmasq to provide DHCP server for Radio Units to be able to access
  Control & Management channel on the CPRI link.

-> Even though both those services are handled via same dnsmasq program, it
   makes sense to split dnsmasq config for clarity and as preparation for
   further adjustments of enb part.

   We also push config rendering down to -core and -enb instances also for
   clarity, and because in enb case rendering will need to know set of
   configured Radio Units - information that will become loaded only at
   instance-enb.

SlapOS provides to each partition dedicated TAP interface, so that an instance
could organize internal networking. In practice this is used by KVM software
release and here in ors-amarisoft, where we feed to eNB such TAP interface for
CPRI-based radio unit so that eNB, in turn, could provide access to CPRI
Control and Management channel via provided TAP.

However there is a problem: SlapOS provides only one TAP interface per
instance, while we need to have one TAP for each Radio Unit.

-> Solve this problem by creating TAP "subinterfaces" per each RU ourselves.

The interfaces we create are full TAP interfaces, just we name them with prefix
based on main interface, and we allocate only part of address space of sole
SlapOS TAP to each subtap. For example if SlapOS provided us slaptap16 with
2401:5180:0:66:a200::/71 IPv6 range and we want to split it for 2 radio units,
we'll be splitting it into 3 regions as follows:

    slaptap16: split 2401:5180:0:66:a200::/71 by 2
    preserve         2401:5180:0:66:a200::/73
    -> slaptap16-1   2401:5180:0:66:a280::/73
    -> slaptap16-2   2401:5180:0:66:a300::/73

Here we preserve 2401:5180:0:66:a200::/73 for usage on original slaptap16, and
we create slaptap16-1 and slaptap16-2 with correspondingly allocated address
range subparts for the RUs.

The splitting is done easily but depends on having networking administration
capability to be able to work. We solve this with employing
/opt/amarisoft/setcap, which we already use for dnsmasq, and with compiled
trampoline program because setcap does not really work directly on scripts.

To avoid hard dependency on having network capability rights, we fallback to
using regular SlapOS slaptap in case there is only one RU.

ru/lopcomm/* and enb.cfg are adapted straightforwardly, but dnsmasq adaptation
is left to a later step not to mix everything into one pile.

NOTE that relying on setcap is not a good in the long term and should be
     reworked once SlapOS is improved to provide ability for instances to
     request several TAP interfaces. Please see discussion at
     nexedi/slapos!1471 (comment 194356)
     for details.

This is preparatory step for multiRU: when there will be several LTE cells,
each possibly having different RF mode, we'll need to configure DRB per-cell.

-> Move DRB configuration to separate jinja2 template to prepare to handle that.

This is 99% movement only, without changing the code for DRB profile. We'll
adjust the DRB profile a bit as another preparatory step in the next patch.

Lopcomm part of the SR already has some partial support for cell_list: if
multiple cells are defined there enb.cfg will have multiple CPRI radio units
and multiple cells configured. But so far all promises, except cpri-link, were
done only for one RU.

-> Fix that by starting to generalize RUlib code to handle multiple radio
units, invoking model-specific RU driver for each RU, and adjusting ru/lopcomm
instance code to correctly generate and activate different promises for
different radio units.

After the patch multiRU support is still very incomplete, but it is a step forward.
