* fixup the help messages to align up properly
 * refresh screen width on SIGWINCH

fixes #666

Make indexer keep noise about errors that prevent index generation.
Detect certain errors in the APKs better. And also have the applet
return error in these scenarios.

remount to read-write before trying to create the cache directory
subdirs. fix a fd leak that might prevent remounting back to rw.

The apk cache might be on the readonly media so we need wait with
remounting til after atleast this filehandle is closed.

commit 4e72075f introduced a bug where package installation might happen
in wrong order (reminder for self to separate the package version deduction
to separate step from installation ordering). this restricts the earlier
commit to not mingle with the install order.

This is so we can do x86 --root installs on x86_64 hosts.

Using --arch without --root can make great damage so we only enable it
if --root is used.

Parse these fields from .PKGINFO, and write them to index.

Our build infra does not yet handle properly noarch, so for the
time being we will rewrite them as native packages in index. This
allows the package to be fetched from the proper URL. This feature
will be removed once abuild and the build infra handle noarch
properly.

improves behaviour under certain corner case conditions.

The db parameter to apk_state_commit is not needed so we remove it.

Implement the logic for install_if lines. Update info applet to
also display the install_if related fields.

broke after making the version field an atom because the printf
was not updated accordingly.

commit 4e72075f introduced late locking for top level packages,
but used the wrong package's top level flag for the check. this
fixes a problem that dependencies might not get pulled in.

 * make it as wide as the screen
 * make sure it's drawn after package change
 * and draw it using ansi escapes in line buffered stderr

This allows us to get apk-tools dependencies get reset at proper
time in world. As a bonus, it reduces code amount.

This will fix certain scenarios where multiple packages are
installed with full package files specified on command line
and they depend on each other.

move all files therein to other places. this allows /var to be
mounted from harddisk, but rest of system be run from ramdisk.

this also removes support for historical version of the scripts
database which was obsoleted in 2.0_pre16 (in July 2009).

in accordance with FSH. this also to clear /var of apk related things
as we might want to run /var as harddisk, but rest of system from
ramdisk.

and make the progress bar disappear on regular runs too.

comment out the code that was out for testing. duh.

.. and back to read-only after finishing with modifications.

fixes #512

if package arch is not set, do not append anything to repository.
if arch is set, it is appended to repository.

Use statfs() filesystem type, instead of the device IDs.
