hostsreader_get() used to assign the IP address to both `name` and `ip`
fields in `struct hostsreader`, which led to proxychains effectively
ignoring the contents of /etc/hosts.
only basic testing was done (with 2 socks5 proxies listening on ::1)
but seems to work as intended.
ipv6 support for the hostsreader (/etc/hosts) is not implemented so far.
working directly with the passed variables could lead to bugs when
some lines in the hosts file aren't well-formed and the loop is taken
several times while the buf vars are already modified.
the hostentdb introduced between 4.2 and 4.3
(via af5c6f0c6a )
had several issues:
- it caused breakage on FreeBSD and was commented out there
- prevented usage of the hostdb when proxy_dns was turned off
(issue #42)
- required dynamic memory allocation which was accessed from several
threads
- wouldnt reflect changes to the hosts file made during program run
the only sensible solution is to remove the hostentdb and replace it
with a home-grown hosts parser (we can't use gethostent() since
that would mess up the gethostent()-state from different threads).
the new parser used here is deliberately held simple and only meant
to provide the user with means to reference hardcoded ipv4 addresses
via his hosts file.
