download: Don't use an hardcoded exclude list

Instead of hardcoding --exclude=./dev/*, use a new metadata file
"excludes" which lists all the paths or patterns to exclude during
extraction (one per line).

download: Improve cache handling

This adds a new --force-cache parameter which will force use of the
cache even for expired images.

An expired image is now only flushed from the cache once a new one is
successfuly downloaded (to avoid destroying the local cache when the
host doesn't have internet connectivity).

The ID of the build in cache is also tracked so that we don't
re-download something we already have (should only happen if we don't
have a new build published by the time the previous one expires).

handle simple bashisms:

- [[ ]] -> [ ]
- == -> =
- source -> .
- redirect of fd 200 is error in mksh, use fd 9
- &> /dev/null -> > /dev/null 2>&1
- useless function keyword
- echo -e -> printf

still left bash shebang which did not validate with checkbashism, mostly
due 'type' being reported as bashism

Make ubuntu templates squid-deb-proxy-client aware

This makes the ubuntu and ubuntu-cloud templates automatically aware of apt
proxy settings when the LXC host has "squid-deb-proxy-client" installed. This
makes installations *much* faster when a suitable squid-deb-proxy is
found on the network (or installed on the host).

api change: default container->daemonize to true

Pretty much the only case where we do NOT want to daemonize
a container start is lxc-start.  So make c->daemonize true
by default, and have lxc-start set it to false.

If there are existing API users who rely on daemonize by
default, then they will be broken by this.  It seems we should
do this before beta1 if we're going to do it.

Modify lxc-fedora and lxc-centos for multiple issues...

This is a reissue of two previous patches along with some additional
changes for hardening the root password process based on discussions
on-list.

--
This patch modifies the lxc-fedora and lxc-centos templates for 3 things.

1) Extensively modifies root password generation, storage, and management
    based on discussions on the devel list.

  Root passwords are hardened and have advanced configurability.
    A static password may be provided.
    A password based on a template may be generated, including ${RANDOM}.
    A password may be generated through mktmp using a template with X's.
    Root passwords default to expired, initially.
    Passwords may optionally be echoed to stdout at container creation. (no)
    Passwords may optionally be stored in ${rootfs_path}/tmp_root_pass. (yes)
    Users may be optionally forced to change the password at creation time. (no)
    Default is to generate a pattern based password and store, no force change.
    All of this may be overridden by environment variables through
      conditional assignment.

2) Random static hardware addresses are generated for all configured
    interfaces.

3) Add code to create sysv init style scripts to intercept shutdown and
    reboot to prevent init restart and hang for CentOS and legacy Fedora
    systems on shutdown, reboot, init 0, and init 6.  This solves a variety
    of hang conditions but only affects newly created containers.  Does
    not have any impact on systemd based containers.

lxc-archlinux: Cleanup fstab

It's been brought to my attention that the read-only mount of /proc/sys
is causing problems to archlinux users, so instead just have LXC mount
proc and sysfs normally (read-write).

Fix return value of userns_exec_1

Instead of always returning -1 and call SYSERROR when the child returns
non-zero. Have userns_exec_1 always return the return value from the
function it's calling and let the caller do the error handling (as is
already done by its only caller).

lxccontainer.c: check lxc_conf before referance haltsignal

If we start container with rcfile(see comments in lxc_start.c), it
is possible that we have no config file in /usr/local/var/lib/lxc.
So when we try lxc_stop, lxc_container_new will not load any config
so we'll get c->lxc_conf = NULL.

In that case, we'll get Segmentation fault in lxcapi_shutdown, a
simple check would fix this.
