IMPORTANT: many improvements to low-level software building phase

POSSIBLE EFFECT ON YOUR PROJECT: The changes in this commit may only cause
conflicts to your project if you have changed the software building
Makefiles in your project's branch (e.g., 'basic.mk', 'high-level.mk' and
'python.mk'). If your project has only added analysis, it shouldn't be
affected.

This is a large commit, involving a long series of corrections in a
differnt branch which is now finally being merged into the core Maneage
branch. All changes were related and came up naturally as the low-level
infrastructure was improved. So separating them in the end for the final
merge would have been very time consuming and we are merging them as one
commit.

In general, the software building Makefiles are now much more easier to
read, modify and use, along with several new features that have been
added. See below for the full list.

 - Until now, Maneage needed the host to have a 'make' implementation
   because Make was necessary to build Lzip. Lzip is then used to
   uncompress the source of our own GNU Make. However, in the
   minimalist/slim versions of operating systems (for example used to build
   Docker images) Make isn't included by default. Since Lzip was the only
   program before our own GNU Make was installed, we consulting Antonio
   Diaz Diaz (creator of Lzip) and he kindly added the necessary
   functionality to a new version of Lzip, which we are using now. Hence we
   don't need to assume a Make implementation on the host any more. With
   this commit, Lzip and GNU Make are built without Make, allowing
   everything else to be safely built with our own custom version of GNU
   Make and not using the host's 'make' at all.

 - Until recently (Commit 3d8aa5953c4) GNU Make was built in
   'basic.mk'. Therefore 'basic.mk' was written in a way that it can be
   used with other 'make' implementations also (i.e., important shell
   commands starting with '&&' and ending in '\' without any comments
   between them!). Furthermore, to help in style uniformity, the rules in
   'high-level.mk' and 'python.mk' also followed a similar structure. But
   due to the point above, we can now guarantee that GNU Make is used from
   the very first Makefile, so this hard-to-read structure has been removed
   in the software build recipes and they are much more readable and
   edit-friendly now.

 - Until now, the default backup servers where at some fixed URLs, on our
   own pages or on Gitlab. But recently we uploaded all the necessary
   software to Zenodo (https://doi.org/10.5281/zenodo.3883409) which is
   more suitable for this task (it promises longevity, has a fixed DOI,
   while allowing us to add new content, or new software tarball
   versions). With this commit, a small script has been written to extract
   the most recent Zenodo upload link from the Zenodo DOI and use it for
   downloading the software source codes.

 - Until now, we primarily used the webpage of each software for
   downloading its tarball. But this caused many problems: 1) Some of them
   needed Javascript before the download, 2) Some URLs had a complex
   dependency on the version number, 3) some servers would be randomly down
   for maintenance and etc. So thanks to the point above, we now use the
   Zenodo server as the primary download location. However, if a user wants
   to use a custom software that is not (yet!) in Zenodo, the download
   script gives priority to a custom URL that the users can give as Make
   variables. If that variable is defined, then the script will use that
   URL before going onto Zenodo. We now have a special place for such URLs:
   'reproduce/software/config/urls.conf'. The old URLs (which are a good
   documentation themselves) are preserved here, but are commented by
   default.

 - The software source code downloading and checksum verification step has
   been moved into a Make function called 'import-source' (defined in the
   'build-rules.mk' and loaded in all software Makefiles). Having taken all
   the low-level steps there, I noticed that there is no more need for
   having the tarball as a separate target! So with this commit, a single
   rule is the only place that needs to be edited/added (greatly
   simplifying the software building Makefiles).

 - Following task #15272, A new option has been added to the './project'
   script called '--all-highlevel'. When this option is given, the contents
   of 'TARGETS.conf' are ignored and all the software in Maneage are built
   (selected by parsing the 'versions.conf' file). This new option was
   added to confirm the extensive changes made in all the software building
   recipes and is great for development/testing purposes.

 - Many of the software hadn't been tested for a long time! So after using
   the newly added '--all-highlevel', we noticed that some need to be
   updated. In general, with this commit, 'libpaper' and 'pcre' were added
   as new software, and the versions of the following software was updated:
   'boost', 'flex', 'libtirpc', 'openblas' and 'lzip'. A 'run-parts.in'
   shell script was added in 'reproduce/software/shell/' which is installed
   with 'libpaper'.

 - Even though we intentionally add the necessary flags to add RPATH inside
   the built executable at compilation time, some software don't do it
   (different software on different operating systems!). Until now, for
   historical reasons this check was done in different ways for different
   software on GNU/Linux sytems. But now it is unified: if 'patchelf' is
   present we apply it. Because of this, 'patchelf' has been put as a
   top-level prerequisite, right after Tar and is installed before anything
   else.

 - In 'versions.conf', GNU Libtool is recognized as 'libtool', but in
   'basic.mk', it was 'glibtool'! This caused many confusions and is
   corrected with this commit (in 'basic.mk', it is also 'libtool').

 - A new argument is added to the './project' script to allow easy loading
   of the project's shell and environment for fast/temporary testing of
   things in the same environment as the project. Before activating the
   project's shell, we completely remove all host environment variables to
   simulate the project's environment. It can be called with this command:
   './project shell'. A simple prompt has also been added to highlight that
   the user is using the Maneage shell!
