Final piece of the tree topic. struct tree.size already receives
its values from size_t-shaped sources (odb_read_object() in
repo_parse_tree_gently() and in reflog.c::tree_is_complete()),
so on Windows it was already silently truncating anything past
4 GiB. Switch the field and parse_tree_buffer()'s size parameter
to size_t.
All readers feed tree->size into init_tree_desc(), which was
widened earlier in this topic; the existing parse_object_buffer()
caller in object.c keeps its unsigned long parameter, which
promotes cleanly.

The source files for libgit.a have been moved into a new "lib/"
directory to clean up the top-level directory and clearly separate
library code.

Move libgit.a sources into separate "lib/" directory
t/helper: prepare "test-example-tap.c" for introduction of "lib/"
The Git project is not exactly the easiest project to get started in:
it's written in C and POSIX shell, with bits of Perl, Rust and other
languages sprinkled into it. On top of that, the project has grown
somewhat organically over time, making the codebase hard to navigate.
These are problems that we're aware of, and there have been and still
are efforts to clean up some of the technical debt that is natural to
exist an a project that is more than 20 years old. Furthermore, we
provide resources to newcomers that help them out like our coding
guidelines, code of conduct or "MyFirstContribution.adoc".
But there is a rather practical problem: finding your way around in our
project's tree is not easy. Doing a directory listing in the top-level
directory will present you with more than 550 files, which makes it
extremely hard for a newcomer to figure out what files they are even
supposed to look at. This makes the onboarding experience somewhat
harder than it really needs to be. This isn't only a problem for
newcomers though, as I myself struggle to find the files I am looking
for because of the sheer number of files.
Besides the problem of discoverability it also creates a problem of
structure. It is not obvious at all which files are part of "libgit.a"
and which files are only linked into our final executables. So while we
have this split in our build systems, that split is not evident at all
in our tree.
Introduce a new "lib/" directory and move all of our sources for
"libgit.a" into it to fix these issues. It makes the split we have
evident and reduces the number of files in our top-level tree from 550
files to ~80 files.
This is still a lot of files, but it's significantly easier to navigate
already. Furthermore, we can further iterate after this step and think
about introducing a better structure for remaining files, as well.
