fixes #10688

On some systems the `/var/` dir is mounted in a tmpfs which is reseted
after each reboot. For that reason no post-install script can handle the
creation of the cache dir at `/var/cache/apk`.

Check on database opnening if the folder is available, if not create it.
Fixes #10715

It used to be relative to the --root specified root, but that
causes issues with relative command line filenames and is unintuitive.
Update documentation accordingly. Fixes #10702.

Closes #10708.

unintentional regression from commit edb45ae4
fixes #10707

This uses some macro trickery to make sure that there's one-to-one
mapping with the option index enum and the descriptor. The down
side is that enum's are generated via #define's and editors might
not pick them up for auto completion, but the benefits are more:
it's no longer possible have mismatching enum value and descriptor
index, and the amount of source code lines is less.

Fixes #10667 and #10700

If getservbyname() fails, libfetch will attempt to connect to port 0.

Some triggers and maintainer scripts depend on /dev/random, /dev/urandom,
/dev/zero and /dev/console.

fixes 12fdf6fc "allow building without help..."

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

fixes #10696

define APK_DEFAULT_ARCH for riscv32 and riscv64 targets

See merge request alpine/apk-tools!26

Fixes #10686 to not use uninitialized value in the error paths.

When creating an index apk warns if a dependency is missing a provider.
However when using a multi-arch repository, it's not an error that
a certain architecture is missing a dependency because that dependency
could be in an other architecture. Since apk index doesn't know about
this, add an argument to disable that warning.

Maintainer note: rebased for new option handling, and minor stylistic
adjustments.

This reduces the number of relocations on PIE binaries, and also
reduces the executable size. Parsing of the options is slightly
sped up as only the exact matching option group parser is called.

Also few minor fixups added.
