Add new dependency to Slackware template

I followed the [changelog of Slackware-current]<http://www.slackware.com/changelog/>,
and found that Slackware-current split hostname utility from util-linux package in Nov 17 2017.
So I add the new package to the template.

Update gentoo.moresecure.conf.

Closes https://github.com/lxc/lxc/issues/1928Signed-off-by: i.Dark_Templar <darktemplar@dark-templar-archives.net>

Change conf.c to export function write_id_mapping, which will now be
called inside main function of lxc_unshare.c.

This is required because setuid syscalls only permits a new userns to
set a new uid if the uid of parameter is mapped inside the ns using
uid_map file[1]. So, just after the clone invocation, map the uid passed as
parameter into the newly created user namespace, and put the current uid
as the ID-outside-ns. After the mapping is done, setuid call succeeds.

Closes: #494

Fix errors in configuration file parsing

In addition to the memory corruption fixed in ee3e84df,
this function was also performing invalid memory accesses for the following inputs:
- `lxc.net`
- `lxc.net.`
- `lxc.net.0.`
- `lxc.network`
- `lxc.network.0.`
Signed-off-by: Felix Abecassis <fabecassis@nvidia.com>

This prevent an infinite recursion in the case of "lxc.net.0. = a"

This caused the linked list of appenders to loop on itself, creating
an infinite logging loop in `__lxc_log_append`.
