Somewhat fixing sysvinit and casper legacy support, slightly improved patch from Rui Miguel P. Bernardo <rui.bernardo.pt@gmail.com> (Closes: #772522, #772651).

This however will still not work properly building upstart based
images but they have been broken/unsupported anyway since a long
time.

Fix typo in variable name (LH_LINUX_FLAVOURS instead of LB_LINUX_FLAVOURS) in installer_debian-installer script, affecting the armel architecture (Closes: #770796).

Correcting typo in apt.conf.d directory name, thanks to jnqnfe <jnqnfe@gmail.com> (Closes: #771392).

Correcting stage name check in chroot_includes, thanks to jnqnfe <jnqnfe@gmail.com> (Closes: #771377).

Avoid failing to autocreate live.list.chroot in lb config when using --clean, thanks to jnqnfe <jnqnfe@gmail.com> (Closes: #770637).

The {iso,pxe,ext,sys}linux packages use /usr/lib/{ISO,PXE,EXT,SYS}LINUX/
directories and not /share/{ISO,PXE,EXT,SYS}LINUX/.

The user might not have created any package list or it might have
created a packages list that end up being empty due to various #if tests.
We should not fail in those cases.

With linux 3.16 in Debian Jessie, armmp and armmp-lpae are the
only armhf flavours availale. On armel, we lost the support of
the iop32x flavour.

Dropping prism2-usb-firmware-installer which fetches firmware from (at least) temporarily broken website.

Removing source_includes from toplevel source script, it was a python stub and will come back at a later point.

In general there's no harm in having them as they are not used
on syslinux 4 distributions, however, but it's cosmetically nicer
and the path woudn't match anyway.

But.. since it turned out that we need the second copy of bootloaders
for wheezy anyway as wheezy and jessie are mutually exclusive
regarding paths where syslinux files are located, there's no
point in having them and confusing users with error messages
from cp -aL when stuff can't be dereferenced (which is ok).

Moving partial python rewrite to separate branch, let's do it in the jessie+1 cycle rather than go with the current mixed code.
