phase1,phase2: s/master/main for phase{1,2}

More and more projects are switching their repositories to use the
'main' branch instead of the 'master' branch. This also includes many
Linux upstream trees as well. Some trees are even removing their
'master' branches already.

I think this is becoming more and more mainstream and expected of
projects, so we should do the same.

phase2: fix invalid escape sequence flake8 warning in checksums step

Resolved a flake8 linting warning related to an invalid escape sequence
in the ShellCommand for calculating checksums:

 phase2/master.cfg:739:28: W605 invalid escape sequence '\('
 phase2/master.cfg:739:32: W605 invalid escape sequence '\)'
 phase2/master.cfg:739:35: W605 invalid escape sequence '\('
 phase2/master.cfg:739:39: W605 invalid escape sequence '\)'

The warning was caused by the use of unescaped parentheses in a regular
expression within a sed command.

Use a raw string (with an 'r' prefix) to treat backslashes as literal
characters, ensuring that the regular expression is correctly
interpreted and flake8 does not raise a warning.

This fix ensures that the code adheres to Python's string handling best
practices and maintains the integrity of the regular expression
functionality.

phase2: checksums: split long command line

To make it more readable, diffs smaller, easier to review etc.

Signed-off-by: Petr Štetiar <ynezz@true.cz>

Add linting with flake8 tool

flake8 is a Python tool that glues together pycodestyle, pyflakes,
mccabe, and third-party plugins to check the style and quality of some
Python code.

Currently we've issue in phase2 in checksum step:

 /bin/sh: 2: Syntax error: ")" unexpected

And it seems, that flake8 is able to spot places which might lead to
such issues during runtime:

 phase2/master.cfg:733:151: W605 invalid escape sequence '\('
 phase2/master.cfg:733:155: W605 invalid escape sequence '\)'
 phase2/master.cfg:733:158: W605 invalid escape sequence '\('
 phase2/master.cfg:733:162: W605 invalid escape sequence '\)'

So lets enable flake8 checking on the CI so we can spot similar places
in the future and address them before deployment.

We dont want to make current ongoing work on phase2 code harder, thus we
don't touch that part yet, so we whitelist most of the checks for now.

phase1: raise priority of tag builds

Currently the buildmaster would only order tag builds within their own
branch, meaning that if e.g. a higher priority branch has normal
buildrequests (i.e. buildrequests comming from the AnyBranchScheduler),
and a lower priority branch has "tag" buildrequests (i.e. from the
Triggerable scheduler), the former builderequests would be served first,
deferring the build of e.g. release tags.

We want forced builds (release tag) to have maximum priority, regardless
of branch priority. This commit attempts to solve this problem by
leveraging the newly (as of buildbot 3.9.0) introduced "priority"
scheduler parameter, by raising the Triggerable scheduler buildrequests
priority, and then considering this higher priority in Builders' order.

The net result is that Builders are now prioritized if they have
pending higher priority buildrequest, still preserving the branch order.
In other words, tag requests are front run while preserving branch order,
meaning that if two branches have tag buildrequests, the higher priority
branch is still served first.

This requires buildbot 3.9.0

new `qualcommax/ipq807x` subtarget on `openwrt-23.05` branch as well.

Thibaut later explained, that this is by design, his initial idea was to
find exhaustive list of all targets and let the `checkarch` step do the
final triaging.

I find this approach confusing, because if the subtarget is not present
in that branch, we shouldn't have builder for it configured as well.
Furthermore wasting roughly 5 minutes of precious buildworker time to
checkout all feeds and then just find out, that we're not going to use
those seems suboptimal as well.

phase1: workaround gitverify 1st build failures on fresh workers

Currently every 1st build on ephemeral build worker results in the
failure of the `gitverify` build step as the stock buildbot Git() build
step for some reasons just clones the Git repository into detached HEAD
state.

On the 2nd build using the same build worker Git() checkouts the branch
and thus makes `gitverify` step happy and the builds then continues
normally.

This needs to be fixed properly, either by adjusting the `gitverify`
check or adding suitable `mode` into Git() build step, but this needs
more time and testing.

So for now, lets simply workaround that issue by running Git() step two
times.

docker,worker: install g++-multilib

From [openwrt/docker@5484951][1] (GitHub PR [#89][2]):

Node fails to cross-compile from a 64-bit build machine to 32-bit host
with the following error:

```
  In file included from /usr/include/c++/8/memory:62,
  from ../deps/v8/src/libplatform/default-foreground-task-runner.h:8,
  from ../deps/v8/src/libplatform/default-foreground-task-runner.cc:5:
  /usr/include/c++/8/bits/stl_algobase.h:59:10: fatal error: bits/c++config.h:
    No such file or directory
  #include <bits/c++config.h>
          ^~~~~~~~~~~~~~~~~~
  compilation terminated.
```

On Debian, `g++-multilib` can be installed to fix this.

phase1: actually make rsync -4 configurable

54e80d5ce introduced an interpolate bug that would evaluate an empty
string as being part of the arguments passed to rsync, resulting in a
failure as rsync interprets that empty string as a source.

This commit fixes this by instead appending '4' to regular shortopts
when necessary.

buildmaster: fix unpinned buildbot package version

It seems, that current pip3 install pinning doesnt work properly as it
can result in the following package versions installation:

 buildbot-3.6.1 buildbot-console-view-3.5.0 buildbot-grid-view-3.5.0
 buildbot-waterfall-view-3.5.0 buildbot-worker-3.5.0 buildbot-www-3.5.0

So lets pin the buildbot package itself to BUILDBOT_VERSION as well.

phase1: make 'rsync -4' worker-configurable

We set '-4' in rsync_defopts, asking rsync to "prefer" ipv4 whenever
possible on _all_ workers. This was historically done because some
workers had flaky ipv6 connectivity, however in the future the reverse
may be true, with worker having worse networking over ipv4 than ipv6.

This change introduces an 'rsync_ipv4' worker configuration option:
when set to a true value, the old rsync behavior (adding '-4') is used,
when unset or set to false, the extra rsync argument is not used.

phase1: call host ccache in stats

We do not use the staging_dir ccache on buildbots (config seed contains
CONFIG_CCACHE=n), only the host tool if present.
Also only execute this step if 'ccache_command' is set.

This will simplify reporting and ensure consistent build statistics.
It will also simplify prioritizing builders by branch.

This also introduces a single "trigger" scheduler that will handle all
trigger requests for each branch/target combination, speeding up the
forcing of builds.
