The files contrib/dist/tor.sh and contrib/dist/suse/tor.sh should not
exist anymore, but when building in same repository for older versions
of Tor, these files may return and not be cleaned up properly. This
commit unignores those files from .gitignore, in order to make it clear
that these files are no longer auto-generated and should be cleaned up.

This code was in our process module, but it doesn't belong there:
process is for launching and monitoring subprocesses, not for
hardening the current process.

This change lets us have our subsystem init order more closely match
our dependency order.

lib/confmgt is at a higher level than lib/conf, since it needs to
call down to logging and similar modules.

This code tries to prevent a large number of possible errors by
enforcing different restrictions on the messages that different
modules publish and subscribe to.

Some of these rules are probably too strict, and some too lax: we
should feel free to change them as needed as we move forward and
learn more.

This module implements a way to send messages from one module to
another, with associated data types.  It does not yet do anything to
ensure that messages are correct, that types match, or that other
forms of consistency are preserved.

We now accumulate warning flags in a separate variable,
"TOR_WARNING_FLAGS", and write it to a "warning_flags" file.  Then
we test whether the compiler will accept "@warning_flags": if so, we
put "@warning_flags" in the CFLAGS; if not, we copy the contents of
"$TOR_WARNING_FLAGS" into the CFLAGS.

Closes ticket 28924.

This patch removes the old process_handle_t code. Everything should by
now be using the process_t interface.

This patch adds test cases for process_t which uses Tor's main loop.
This allows us to test that the callbacks are actually invoked by the
main loop when we expect them.

This is a very gentle commit that just lays the groundwork in the
build system: it puts the include files to build libtor-app.a into
src/core, and to build the tor executable into src/app.  The
executable is now "src/app/tor".

(Term is short for terminal)

Note that procmon does *not* go here, since procmon needs to
integrate with the event loop.

Note that the workqueue code does *not* go here: it is logically at
a higher level, since it needs to use libevent and the networking
stack.

libtor-encoding is about various ways to transform data to and from
character sequences.

There are some additional changes to come: those points are marked
by XXXX.

The smartlist_core library now contains only the parts of smartlists
that are needed for the logging library.  This resolves the
circularity between "container" and "log".

The "containers" library still uses the logging code, and has the
higher-level smartlist functions.

The locking code gets its own module, since it's more fundamental
than the higher-level locking code.

Extracting the logging code was the whole point here. :)

The other time stuff is higher-level
