and generate index if it is missing, even if all packages are up2date.

like when main package depends on subpackages

So we can support multiple kernels in parallel.

Use the built repositories as source for the iso components rather than
just pick whats in a given dir.

alpine-baselayout does it.

and dont build index if its not needed

-P lets user specify the REPODEST on cmd line

This allows ABUILDS to call the default_doc func and append stuff missing

- check that md5sums correspond to source
- warn if maintainer is missing

so far only option avaiable is !strip, which disables stripping of binaries.

The -r option will only install deps from system repo and fail if any is
missing.

The -R option will parse the aports tree and try build the missing packages
and then install the newly built package.

set default repositories

abuild [-c] -n PKGNAME[-PKGVER]
creates a directory with new APKBUILD. If -c is specified will sample init.d,
conf.d and install script be copied as well.

Read the version from .alpine-release on media. Also display the init
script version.

also create the symlink for kernel modules

This reverts commit fe7da984.

Conflicts:

	abuild

by sourcing the functions.sh after abuild.conf

I'm not sure if we really want this
