At the end of September 2021, Let's Encrypt's DST Root CA X3
certificate expired, and the new ISRG Root X1 took over.
Update the CI template so that the new certificate is available and we
can keep on cloning the libmbim/libqmi/libqrtr-glib repos without
failures.

Both `libmbim` and `libqrtr-glib` have started using `feature`
options in their meson builds.

The CI options when building `libmbim` and `libqrtr-glib` have been
updated to use `feature` option values.

Although not totally necessary due to its implementation, some files
built by meson are included as content files.

They have been explicitly added for the sake of correctness.

`install_header` allows the use of the `subdir` parameter that
points to the subdirectory in the `includedir` directory.

However, to maintain consistency, this has been changed to use the
`install_dir` parameter.

Since meson 0.49, a new argument called `kwargs` can be used to pass
a dictionary to specify different parameters[0].

This feature has been used to make test builds more readable.

Since meson 0.50, `include_directories` also include strings[0].
This feature is used to improve slightly build files.

Since meson 0.47, `install_mode` option can be used to set a given
set of rights to any target.

This feature has been used to set `qmi-network` rights instead of
using a post install script.

The option is only used to set the `MM_RUNTIME_CHECK_ENABLED` define
so there is no need to have a variable for it.

The option is used directly and the linked variable has been
removed.

Since meson 0.47, there is support for features build options[0] that
can be enabled automatically if the system has the required support.

This feature has been used for some options that fit properly for
their needs.

The setup of the CI builds have also been apropiately updated.

A new variable called `qmi_name` has been created to avoid the call
to a function inside the meson object.

meson's test function already sets the `MALLOC_PERTURB_` environment
variable[0], so there is no need to set it.

meson gained the dictionaries as builtin objects[0] that can be
modified with the addition operator[1] and can be useful when
setting configuration or even environment values[2].

The individual object creation has been replaced by dictionaries
when possible.

meson is able to process or discard a directory based on a
dependency object based on if it is found or not[0].

The `man` directory depends on the `help2man` program so it has been
changed to take advantage of this feature.

Since meson 0.49, the `/` character can be used to join paths[0], so
all the instances of `join_paths` have been replaced.

Since meson 0.53, it has added a new function to summarize the build
configuration[0].

The summary has been changed to make use of it.

meson version has been bumped to 0.53.

Since 0.48 version of meson, there is a new generic `python` module
and the previous `python3` module has been deprecated[0].

The use of the `python3` module has been replaced by this new
`python` module.

meson version has been bumped to 0.48.

CI has also been updated to have this meson version available.

The qmimcli `bash-completion` file has the `-completion` suffix as
it can be overriden by the generated qmimcli binary file. However,
meson builds the binary field in a different build directory so there
is no need to have it renamed.

(cherry picked from commit dd7e6296)

Equivalent of AT+CLCC to retrieve information about all current calls

We should be able to build with QRTR support but without introspection
support.

Using -Dintrospection=false would actually not disable it. There is no
longer an "auto" option for the introspection support, it will be
either enabled or disabled depending on what the user asks
for (default enabled).

To avoid the burden of maintaining multiple build systems, autotools
support has been removed.

Inigo Martínez authored 3 years ago and Aleksander Morgado committed 3 years ago

In order to allow the removal of autotools, all related builds have
been removed.

This prints a message every time a refresh indication
is received.

To allow detecting via pkg-config whether libqmi was built with rmnet
support, as we do with other build features.
