`build`: do not skip on partial results

`Depends.pm`: remove targets recursively with prune()

`lib`: split to subdirectories

This commit introduces a subdirectory structure for lib. There is no effect on
the installed package (the result of running the `Makefile`), and mainly serves
to improve overview of the different components. Every subdirectory can have
its own documentation with a `README.md` file.

Every subdirectory is self-contained; any programs within only relies on
programs from the same directory, or the AUR `perl` library. `aur-sync` uses
programs from all subdirectories, and is thus left in the main lib directory.

`sync`: automatic `gnupg` key retrieval

This matches the default behavior of gpg.

In certain cases, the `auto-key-retrieve` option for gpg(1) does not result in
a successfully imported keys. Furthermore, this option imports (possibly
unverified) keys directly into the default user keyring. Use a different
approach by creating a separate keyring which is used exclusively for verifying
and importing gpg(1) keys with makepkg(8) or aur-chroot(1).

The keyring location defaults to `$XDG_DATA_HOME/aurutils/sync/gnupg` and can
be modified through the `AUR_SYNC_GNUPGHOME` environment variable. Automatic
key retrieval can be disabled with `--no-key-retrieve` / `--nokeyretrieve`.

This allows using a separate keyring for signature verification with makepkg(8)
and package signing with gpg(1). The keyring location can be specified through
`AUR_MAKEPKG_GNUPGHOME` in the environment, or `--makepkg-gnupghome` which
takes precendence.

chroot: unbreak `--path`

Avoid triggering the implied `--status` when `--path` is given.

Fixes: 3c282892 ("chroot: make --status default if no modes are specified")

Since `aur-build` runs `aur-chroot --create` on every call, printing
this becomes too chatty.

Partial revert of commit 3c282892

chroot: make --status default if no modes are specified

This matches `aur-repo` behavior. In addition, if $directory/root is
existing, print `there is nothing to do` with `--create`.

perl: refactor library structure

* Move `Repo.pm` to `aur-repo-parse`
* Move `Depends::vercmp` to `Vercmp.pm`
* Move `Depends::solve` to `aur-depends`

* extract() -> recurse()
* get() -> solve()

Partial adaptation from ca8c02dd

view: set orderFile on every call

This moves the `git orderFile` logic from `aur-sync` to `aur-view`.
Incidentally this was the only remaining `git` call in `aur-sync`.

Calling `git config orderFile` on every `aur-view` call, instead of
after a `git clone`, ensures `orderFile` always points to a valid path.
For example, if `HOME=/temphome/user` aur sync ...` is run for a series
of new(ly cloned) packages, subsequent calls `aur sync ...` using the
default `HOME=/home/user` value would still rely on the orderFile in
`/temphome/user`. This leads to errors if the path is deleted.

Closes #1167

repo: warn when local repo is not configured

In #1110 a mandatory check was added for the local repository to be
configured in pacman.conf. However, the bulk of the aur-repo
functionality is available without configuration in pacman.conf,
provided the repository root (`--root`) is specified by the user.
