Tagged release 0.16.16.

rak::regex was a hand-rolled glob matcher supporting only '*'
wildcards. Replace it with the standard POSIX fnmatch() which supports
the same glob patterns plus '?' and '[...]' character classes.

- src/core/manager.cc: use fnmatch for directory entry filtering
- src/command_download.cc: use fnmatch for file path pattern matching
- Makefile.am: remove rak/regex.h from EXTRA_DIST
- rak/regex.h: deleted, no longer needed

-BUILDING

- Run "aclocal -I scripts && autoconf -i && autoheader && automake --add-missing"
-to generate the configure scripts if necessary. The man page "doc/rtorrent.1"
-must be generated with "docbook2man rtorrent.1.xml" if it is missing.
-
- Note that rtorrent follows the development of libtorrent closely, and
-thus the versions must be in sync. This should not be nessesary in the
-future, when the library API stabilizes.

+BUILDING
+--------
+
+Jump into the github cloned directory
+
+```
+cd rtorrent
+```
+
+## Install build dependencies
+
+Install [libtorrent](https://github.com/rakshasa/libtorrent) with the same version rTorrent.
+
+Generate configure scripts:
+
+```
+autoreconf -ivf
+```
+
+Optionally, generate man pages:
+
+```
+docbook2man rtorrent.1.xml
+```
+
+Man pages output to "doc/rtorrent.1".
+
+RTorrent follows the development of [libtorrent](https://github.com/rakshasa/libtorrent) closely, and thus the versions must be in sync.
+
+## USAGE
+
+Refer to User Guide: https://github.com/rakshasa/rtorrent/wiki/User-Guide
+
+## LICENSE
+
+GNU GPL, see COPYING. "libtorrent/src/utils/sha_fast.{cc,h}" is
+originally from the Mozilla NSS and is under a triple license; MPL,
+LGPL and GPL. An exception to non-NSS code has been added for linking to OpenSSL as requested by Debian, though the author considers that library to be part of the Operative System and thus linking is allowed according to the GPL.
+
+Use whatever fits your purpose, the code required to compile with
+Mozilla's NSS implementation of SHA1 has been retained and can be
+compiled if the user wishes to avoid using OpenSSL.

+#   AX_PROG_LUA[([MINIMUM-VERSION], [TOO-BIG-VERSION], [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])]
+#   AX_LUA_HEADERS[([ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])]

+#
+# DESCRIPTION
+#
+#   Detect a Lua interpreter, optionally specifying a minimum and maximum
+#   version number. Set up important Lua paths, such as the directories in
+#   which to install scripts and modules (shared libraries).
+#
+#   Also detect Lua headers and libraries. The Lua version contained in the
+#   header is checked to match the Lua interpreter version exactly. When
+#   searching for Lua libraries, the version number is used as a suffix.
+#   This is done with the goal of supporting multiple Lua installs (5.1,
+#   5.2, 5.3, and 5.4 side-by-side).
+#
+#   A note on compatibility with previous versions: This file has been
+#   mostly rewritten for serial 18. Most developers should be able to use
+#   these macros without needing to modify configure.ac. Care has been taken
+#   to preserve each macro's behavior, but there are some differences:
+#
+#   1) AX_WITH_LUA is deprecated; it now expands to the exact same thing as
+#   AX_PROG_LUA with no arguments.
+#
+#   2) AX_LUA_HEADERS now checks that the version number defined in lua.h
+#   matches the interpreter version. AX_LUA_HEADERS_VERSION is therefore
+#   unnecessary, so it is deprecated and does not expand to anything.
+#
+#   3) The configure flag --with-lua-suffix no longer exists; the user
+#   should instead specify the LUA precious variable on the command line.
+#   See the AX_PROG_LUA description for details.
+#
+#   Please read the macro descriptions below for more information.
+#
+#   This file was inspired by Andrew Dalke's and James Henstridge's
+#   python.m4 and Tom Payne's, Matthieu Moy's, and Reuben Thomas's ax_lua.m4
+#   (serial 17). Basically, this file is a mash-up of those two files. I
+#   like to think it combines the best of the two!
+#
+#   AX_PROG_LUA: Search for the Lua interpreter, and set up important Lua
+#   paths. Adds precious variable LUA, which may contain the path of the Lua
+#   interpreter. If LUA is blank, the user's path is searched for an
+#   suitable interpreter.
+#
+#   Optionally a LUAJIT option may be set ahead of time to look for and
+#   validate a LuaJIT install instead of PUC Lua. Usage might look like:
+#
+#     AC_ARG_WITH(luajit, [AS_HELP_STRING([--with-luajit],
+#         [Prefer LuaJIT over PUC Lua, even if the latter is newer. Default: no])
+#     ])
+#     AM_CONDITIONAL([LUAJIT], [test "x$with_luajit" != 'xno'])
+#
+#   If MINIMUM-VERSION is supplied, then only Lua interpreters with a
+#   version number greater or equal to MINIMUM-VERSION will be accepted. If
+#   TOO-BIG-VERSION is also supplied, then only Lua interpreters with a
+#   version number greater or equal to MINIMUM-VERSION and less than
+#   TOO-BIG-VERSION will be accepted.
+#
+#   The Lua version number, LUA_VERSION, is found from the interpreter, and
+#   substituted. LUA_PLATFORM is also found, but not currently supported (no
+#   standard representation).
+#
+#   Finally, the macro finds four paths:
+#
+#     luadir             Directory to install Lua scripts.
+#     pkgluadir          $luadir/$PACKAGE
+#     luaexecdir         Directory to install Lua modules.
+#     pkgluaexecdir      $luaexecdir/$PACKAGE
+#
+#   These paths are found based on $prefix, $exec_prefix, Lua's
+#   package.path, and package.cpath. The first path of package.path
+#   beginning with $prefix is selected as luadir. The first path of
+#   package.cpath beginning with $exec_prefix is used as luaexecdir. This
+#   should work on all reasonable Lua installations. If a path cannot be
+#   determined, a default path is used. Of course, the user can override
+#   these later when invoking make.
+#
+#     luadir             Default: $prefix/share/lua/$LUA_VERSION
+#     luaexecdir         Default: $exec_prefix/lib/lua/$LUA_VERSION
+#
+#   These directories can be used by Automake as install destinations. The
+#   variable name minus 'dir' needs to be used as a prefix to the
+#   appropriate Automake primary, e.g. lua_SCRIPS or luaexec_LIBRARIES.
+#
+#   If an acceptable Lua interpreter is found, then ACTION-IF-FOUND is
+#   performed, otherwise ACTION-IF-NOT-FOUND is performed. If ACTION-IF-NOT-
+#   FOUND is blank, then it will default to printing an error. To prevent
+#   the default behavior, give ':' as an action.
+#
+#   AX_LUA_HEADERS: Search for Lua headers. Requires that AX_PROG_LUA be
+#   expanded before this macro. Adds precious variable LUA_INCLUDE, which
+#   may contain Lua specific include flags, e.g. -I/usr/include/lua5.1. If
+#   LUA_INCLUDE is blank, then this macro will attempt to find suitable
+#   flags.
+#
+#   LUA_INCLUDE can be used by Automake to compile Lua modules or
+#   executables with embedded interpreters. The *_CPPFLAGS variables should
+#   be used for this purpose, e.g. myprog_CPPFLAGS = $(LUA_INCLUDE).
+#
+#   This macro searches for the header lua.h (and others). The search is
+#   performed with a combination of CPPFLAGS, CPATH, etc, and LUA_INCLUDE.
+#   If the search is unsuccessful, then some common directories are tried.
+#   If the headers are then found, then LUA_INCLUDE is set accordingly.
+#
+#   The paths automatically searched are:
+#
+#     * /usr/include/luaX.Y
+#     * /usr/include/lua/X.Y
+#     * /usr/include/luaXY
+#     * /usr/local/include/luaX.Y
+#     * /usr/local/include/lua-X.Y
+#     * /usr/local/include/lua/X.Y
+#     * /usr/local/include/luaXY
+#
+#   (Where X.Y is the Lua version number, e.g. 5.1.)
+#
+#   The Lua version number found in the headers is always checked to match
+#   the Lua interpreter's version number. Lua headers with mismatched
+#   version numbers are not accepted.
+#
+#   If headers are found, then ACTION-IF-FOUND is performed, otherwise
+#   ACTION-IF-NOT-FOUND is performed. If ACTION-IF-NOT-FOUND is blank, then
+#   it will default to printing an error. To prevent the default behavior,
+#   set the action to ':'.
+#
+#   AX_LUA_LIBS: Search for Lua libraries. Requires that AX_PROG_LUA be
+#   expanded before this macro. Adds precious variable LUA_LIB, which may
+#   contain Lua specific linker flags, e.g. -llua5.1. If LUA_LIB is blank,
+#   then this macro will attempt to find suitable flags.
+#
+#   LUA_LIB can be used by Automake to link Lua modules or executables with
+#   embedded interpreters. The *_LIBADD and *_LDADD variables should be used
+#   for this purpose, e.g. mymod_LIBADD = $(LUA_LIB).
+#
+#   This macro searches for the Lua library. More technically, it searches
+#   for a library containing the function lua_load. The search is performed
+#   with a combination of LIBS, LIBRARY_PATH, and LUA_LIB.
+#
+#   If the search determines that some linker flags are missing, then those
+#   flags will be added to LUA_LIB.
+#
+#   If libraries are found, then ACTION-IF-FOUND is performed, otherwise
+#   ACTION-IF-NOT-FOUND is performed. If ACTION-IF-NOT-FOUND is blank, then
+#   it will default to printing an error. To prevent the default behavior,
+#   set the action to ':'.
+#
+#   AX_LUA_READLINE: Search for readline headers and libraries. Requires the
+#   AX_LIB_READLINE macro, which is provided by ax_lib_readline.m4 from the
+#   Autoconf Archive.
+#
+#   If a readline compatible library is found, then ACTION-IF-FOUND is
+#   performed, otherwise ACTION-IF-NOT-FOUND is performed.

+# SYNOPSIS
+#
+#   AX_REQUIRE_DEFINED(MACRO)
+#
+# DESCRIPTION
+#
+#   AX_REQUIRE_DEFINED is a simple helper for making sure other macros have
+#   been defined and thus are available for use.  This avoids random issues
+#   where a macro isn't expanded.  Instead the configure script emits a
+#   non-fatal:
+#
+#     ./configure: line 1673: AX_CFLAGS_WARN_ALL: command not found
+#
+#   It's like AC_REQUIRE except it doesn't expand the required macro.
+#
+#   Here's an example:
+#
+#     AX_REQUIRE_DEFINED([AX_CHECK_LINK_FLAG])
