TLS_client_method is a LibreSSL extension.
SSLv23_client_method is generic, and doesn't mean SSL v2/v3 only.

list: use `apk list --providers` to search virtual providers instead of enabling virtuals by default

list does everything search does and more

The list applet provides a convenient way of inspecting both the available
and installed package databases by listing their contents.  In some ways,
it is similar to `apk search` but is considered to be a superset of
`apk search` functionality.

A few `apk list` criterion are not yet ready though, such as `apk list --depends`
which searches by runtime dependency (replacing `apk info --rdepends`).

Internally the value is in seconds, but on command line it's in
minutes.

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.

fixes #8161

This unloads --force as several of the things are really not wanted
together. E.g. --force-refresh is a lot different from --force-broken-world
and doing --force to get the other might introduce unwanted behaviour.

--force is still kept for backwards compatibility and it enables
most things --force was used for.

ref #8161

This flag enables a group of options used during initramfs tmpfs
initial install.

This flag skips running hook scripts

This flag *must* be used during initramfs tmpfs initial install.
The reason that this new flag is needed is that the hooks will currently
always fail as musl and /bin/sh is missing at this stage on diskless.

fixes #8160

This change just changes to keep deleted directory items in
the hash with ref count zero and modified flag set. Those entries
are reused when needed. The side effect is that fire_triggers()
will now see those removed direcotries and reports them. Other
enumerators of the directories hash are protected to skip removed
directories when appropriate.

This fixes couple of valgrind reported leaks - though they are
non-important since the leak happens on "exit" only and kernel
frees it anyway.

In discovery phase, there was logic to not process packages
multiple times. However, that logic failed to account the package's
depth and install_if state for the name being processed. This
caused install_if processing failure in certain topologies of the
dependency graph. Adds also a test case that should catch this
issue reliably.

This ensures a swap is emitted when replacing a virtual with
apk add.

By introducing a new package metadata field, `provider_priority`
(index letter `k`), we can specify default packages to satisfy a
virtual.

If a user wishes to select an alternative provider for the virtual,
a changeset swapping the default provider for the selected provider
will be generated by the dependency resolver.
