The apk_fsdir_file_digest() servers dual purpose: to calculate
the checksum, but also to determine if the file exists. Move
it's error check where it originally was.

This moves and isolates the tar code to tar.c. And the actual
file extraction to disk is moved to extract.c.
A new API is introduced and used for v2 file extraction. This
essentially moves and isolates the apk_sign_ctx_* beast into
extract_v2.c and offers a saner interface to handling packages.
A place holder is added for v3 extraction.
The new v3 applets don't use it, and eventually all applets will
use the new formats only.
This prepares the code for this, and moves trust, id_cache, and
root_fd to apk_ctx which is enough for v3 applets at this time.
The generic code is made to not initialize apk_database if it's
not needed.
This is a flat buffers inspired format that allows fast
mmaped access to the data with low overhead, signature support
and relatively good forward support.
This greatly helps with memory management on applications that
may want to daemonize and open/close database several times.
Also the lifetime and "owner" of memory for all data is now
explicitly bound to owning struct apk_database, which might
be helpful when writing language bindings. As side effect, the
interned "atoms" are unique only within what apk_database, so
comparing packages from different apk_database may not work
as expected.
Fixes#10697
If apk is run as a non-root user, it's not possible to chown files.
Maintainers note: minor wording changes on commit log and man page.

This modifies apk cache for indexes to be automatically refreshed
periodically without explicit 'update' or '--update-cache' usage.
The default is to do if-modified-since request if the local copy
is older than 4 hours. This age can be changed with --cache-max-age.
Using --update-cache will change this age to 60 seconds to make
sure the cached copy is relatively new. The small age is in order
to try to avoid downloading indexes second time when apk-tools is
upgraded and apk re-execs after self-upgrade.
Accordingly using explicitly 'apk update' will now enforce
--force-refresh and request the very latest index by requesting
any potential http proxy to do refresh too.
This allows for instance integration of etckeeper
[TT: Reorganized code a bit, and modified to use single
directory commit_hooks.d with argument for script of stage.]
resolve reverse dependencies after all packages have been loaded,
and avoid traversing the reverse name lists. now that we use
automatic virtual packages (soname, pkg-config, etc.) the reverse
dependency chains can become considerable longer than what it was
when the rdependency construction code was originally written.
there are only few combinations for that triplet, and they
occur multiple times reducing the struct sizes a bit. make
sane defaults and prepare to not write defaults to disk
to reduce on-disk installed db size.
Apk used to reset directory permissions always, but this is undesirable
if user has modified the permissions - especially during tmpfs boot.
Though, it is desirable to update the permissions when packaging has
changed permissions, or a new package is installed and the merged
permission mask / owner changes.
Thus the new code updates the permissions only if:
1) We are booting and directory is not in apkovl
2) The directory is modified by a package install/remove/upgrade
3) The filesystem directory permission matched database
Additionally "apk fix --directory-permissions" can be used to reset
all directory permissions to the database defaults.
Fixes#2966
This implements a new protected path flag '!' to include always
matching entries in the backup mode (overlay). This is also turned
on for etc/apk to include everything there in overlay, because
the full list of repositories and signing keys need to be in
overlay - just getting them from a package is not enough during
bootstrap.
make cache a special kind of repository, and automatically cache
special packages (virtual packages, or ones installed from command
line). add test cases for handling virtual packages. fixes#1617.
If a directory has protection mask, but does not exist in db, we
do not handle it right unless we calculate the protection mask by
hand, or create temporary db dir entry for it. For simplicity create
always the db dir entry -- depending on audit type we likely need
to create it anyway. This commit also caches the db dir entry in the
audit tree context to avoid duplicate lookups. ref #1241.
apk_name_state is now quite small; and we avoid overhead of two
pointers (+ malloc overhead) when we just make it part of apk_name.
It also fixes some problems (that got introduced) where apk_name_state
was not allocated.
