The code below lib.distro, as left behind by the previous commit, is
geared towards being directly used as a command-line API. This commit
introduces the abstract base class Distro, a proxy for
distribution-specific interactions. The proxy abstracts distro
specifics into an API with proper method prototypes, not
argparse.Namespace contents, and can thus be more easily driven by
arbitrary code.
The Distro class is initialized with a member variable of type
ExecContext, another new class introduced by this commit. It is
designed to abstract the communication channel to the distribution
instance. Currently only one specialization exists, Local, which
interacts with the distribution and root file system it is running
in, but is planned to be subclassed to support interaction via SSH,
serial, chroot, or chains thereof.

Currently git-get-% pulls into the master branch. Change that to pull
into the branch currently checked out in the workspace, because
that's the more likely use case if you want a quick update from
somewhere.

"clone" in the Git sense means to copy a remote project over from
scratch. pgit.sh clone has come from that, but has since evolved into
something different, a mixture of clone, pull and fetch, so find a
different name. "get" seems generic enough and doesn't clash with a
Git meaning. Adapt variable names accordingly across the project.

git-pull-<username> doesn't use pgit.sh if username == login.
pgit.sh should handle that case fine now, so remove the distinction
from topdir.mk and make it in one place, i.e. pgit.sh. This has the
additional advantage that pull as done by pgit.sh conveniently uses
--autostash.

Use pgit.sh to for the git-pull-% target. This should make
git-pull-maintainer work. To limit the blast radius for now, only use
it if the source user differs from the invoking user.

Retire pkg-manager.sh and replace it by the cleaner "jw-pkg.sh
distro" command, essentially providing the same functionality and
nearly the same command-line interface.

400 LOC more. That's what the move from a shell script to the more
maintainable Python versions costs. Still a good idea, and the
enhanced extensibility might pay off in terms of LOC with other shell
scripts in the future.

jw-projects.py is now a multi-call executable, with "projects" being
just one of its subcommands. Rename it to jw-pkg.py to reflect that.

Reorganize the Python module structure. Placing the command classes
under jw.cmds.projects instead of jw.build.cmds will allow to add a
nested command structure, with the current commands, being mostly
related to building software, found below a "projects" toplevel
command.
Other conceivable commands could be "package" for packaging, or
"distro" for commands wrapping the distribution's package manager.

This commit aims at improving speed by using better caching.
- Makefile, cache.mk: Split .cache.mk up
To allow caching of runtime path variables which are
project-specific, split .cache.mk up in .cache-project.mk and
.cache-projects.mk
- ldlibpath.mk: Cache ldlibpath, exepath and pythonpath
Place the output of $(call proj_query ldlibpath), $(call
proj_query, exepath) and $(call proj_query pythonpath) in
JW_PKG_LD_LIBRARY_PATH, JW_PKG_EXE_PATH, and JW_PKG_PYTHON_PATH
respectively, and cache the variables in make/.project-cache.mk.
- cache.mk: Use = instead of :=
Recursively expanded variables are nearly as fast as := variables
if the assigned value is a fixed string. And sometimes it's not,
rightly so, because variables get assigned below, as with
JW_PKG_XXX for instance.
- cache.mk: Use $(TOPDIR) as variable values
Replace absolute references to project's topdir by $(TOPDIR) with
sed. As soon as the project queries produce absolute paths, they
will be transformed into relative paths which allow the code base
to be moved to a different location and still remain functional
without a rebuild.

There's little system in the pkg-install-xxx targets, add one more to
increase the confusion. It's needed to install all packages needed to
do a standalone build against the packages installed into the system
via package manager. That said, the respective jw-projects.sh
commands need broader refactoring, as well as the pkg-install-xxx
target naming.

jw-build doesn't stop at building software, packaging it afterwards
is also a core feature, so this commit gives the package a better
name.
The commit replaces strings s/jw-build/jw-pkg/ in text files and file
names. Fallout to the functionality is fixed, variable names are left
as they are, though. To be adjusted by later commits.

git-pull-% pulls whatever $(GIT_MAIN_BRANCH) happens to be
from the remote jw-% into the current branch, with --rebase and
--autostash.
git-pull-maintainer does the same with <maintainer>. <maintainer> is
figured out from the configuration in projects.conf. If it's the
invoking user, origin is used.
