When using apk to initialise a new rootfs, it is actually what creates
/lib. Adjust apk_db_create() to use a merged /usr layout and create /lib
as a symlink.

FIXME: this should probably be controlled by a flag?

Alpine does not currently follow the /usr merge standard, however it is
possible to create a merged /usr Alpine system by adjusting apk to
correctly rewrite symlinks and avoid installing symlinks where the link
source and target end up in the same path on a /usr merged system.

Implement special handling when unpacking packages to skip these now
redundant symlinks, and adjust others to point to the correct paths.

Should be APK_BLOB_STRUCT here to avoid doing sizeof(*a).

Specifically "version -c" should not skip empty arguments.

make `apk list --quiet` only print the pkgname without version.

This is similar to what apk search --quiet does.

fixes #10883

Macros used have been taken from Loongson's work-in-progress GCC 12
port.

Similar to the package installation path, invalidate the sorted packages
cache on package uninstallation.

fixes commit "db, info: sort installed package based data by package name"
fixes #10970

Instead of a package just providing the name

fixes commit "del: fix --rdepends" to not delete provided names
if not using --rdepends

fixes #10898

Fixes commit d5ff6c96 "support --from=FROMSPEC". The condition
to generate the reverse dependencies changed causing it not to
be always generated. Fix this by unconditionally generating it.

fixes #10896

Seems originally it was indeed -L, but was inadvertently changed
to -l in 2.12_rc1 in options refactoring commit 1d7123d8. Since
already the 2.12-stable uses -l, update just documentation.

fixes #10776

implement it also for connecting to hosts

fixes #10869

This is a fixup to the backport commit 67f5a753:
  db, apps: sort display results based on package names

This makes apk_db_foreach_matching_name() act consistently on
between 2.14-stable and master. And updates the call sites where
differing behaviour is needed, and fixes dot and other call sites
to work again.

fixes #10889

the stat64 family of functions were provided as transitional functions,
but when building on glibc with _GNU_SOURCE, or any other supported system,
the stat functions are equivalent to their stat64 counterparts
