Moved the strtol() call into fill_netmask_array() and added additional
error checking to ensure that the strtol() call succeeded.
Error checking code taken from strtol() manpage.

When building a numeric ACL with netmask, range check the supplied
value. In addition, the code to walk the array has been extracted and
"simplified".

This change primarily avoids a gcc warning where timebuf
is never non-NULL. There is no need to check the value to be
inserted as it's checked inside hashmap_insert().
This changeset also lets error return values from hashmap_insert()
propogate instead of clamping them to -1 (not that these are
currently used anyway).

Extracted the transparent proxy logic from reqs.c and placed it into a
separate file.

The notices have been changed to a more GNU look. Documentation
comments have been separated from the copyright header. I've tried to
keep all copyright notices intact. Some author contact details have
been updated.

vector_append() calls vector_insert() which makes a copy
of the passed buffer, so the caller can free its buffer.

This was overriding the automake clean target to clean up
files like *.o by default.

Included the basic grammar and handler functions for the "upstream" and
"no upstream" directives. I still need to update the grammar to match
_all_ the possibilities documented in the tinyproxy.conf file, but at
least it now does as much as the old config parser.

Moved the reverse proxy code from reqs.c into it's own files
(reverse_proxy.c). The code in reqs.c is way too complicated, so I
want to move unrelated code into their own files to simplify the main
concepts in reqs.c.

Added the list of tinyproxy typedefs to the indent command to have them
formatted correctly as well.

I re-indented the source code using indent with the following options:
indent -kr -bad -bap -nut -i8 -l80 -psl -sob -ss -ncs
There are now _no_ tabs in the source files, and all indentation is
eight spaces. Lines are 80 characters long, and the procedure type is
on it's own line. Read the indent manual for more information about
what each option means.

Changed the variable type for the namelen variable to the correct
socklen_t type. The configure script already checked for it, but for
some reason I never got around to actually using it in this function.

Updated the copyright email addresses for Robert James Kaes. The
users.sourceforge.net address should always exist.

tinyproxy does not prompt for any proxy information from the client, it
should not be eating the proxy headers. They are most likely needed by
an upstream proxy.

Changed the internal implementation of the hashmap to maintain the
insert order if the same key is repeated. The insertion is still
constant since we keep track of the head and tail of the bucket
chain.

to handle IPv6 style addresses along with the existing IPv4 and string
addresses. In addition, the hand-rolled "list" code has been replaced
with a vector (code reuse.) Also, the code should be a little easier
to understand (relatively speaking.)
I do need to add some kind of testing framework (in general) to check
that the new code does work with all the formats that will be thrown
at it.

This allows tinyproxy to respond to a request bound to the same
interface that the request came in on. As Oswald explains:
"attached is a patch that adds the BindSame option. it causes
binding an outgoing connection to the ip address of the respective
incoming connection. that way one can simulate an entire proxy farm
with a single instance of tinyproxy on a multi-homed machine."
Cool.

properly. (The sizeof "struct stat" was being used rather than the
proper "struct stat_s". On my system, "struct stat" is 88 bytes long,
while "struct stat_s" is 20 bytes long. Quite a difference!)
