print installed packages in `<name> <version>` format. The format is
currently used in OpenWrt and allows downstream tools to compare what's
installed in the firmware.

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 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.
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.

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.
This creates main help like:
--
usage: apk [<OPTIONS>...] COMMAND [<ARGUMENTS>...]

And applet specific help like:
--
usage: apk add [<OPTIONS>...] PACKAGES...
Description:
apk add adds the requested packages to WORLD and installs (or upgrades)
them if not already present, ensuring all dependencies are met.
Options:
--initdb Initialize a new package database
-l, --latest Disables normal heuristics for choosing which repository to install a
-u, --upgrade When adding packages which are already installed, upgrade them rather
-t, --virtual NAME
Instead of adding the specified packages to WORLD, create a new
--no-chown Do not change file owner or group
