moved everything into /trunk/ to create the standard svn layout, for use with tools that require this (eg. git-svn). IMPORTANT: do NOT do an `svn up`. instead, re-use your working copy's existing files with `svn switch` (http://svnbook.red-bean.com/en/1.6/svn.ref.svn.c.switch.html).
bin/make: moved $make_filter_active test to lib/sh/make.sh make() so that it's also used when make() is run directly (e.g. in a runscript) rather than via the bin/make wrapper in the PATH
bugfix: bin/make: use separate $make_filter_active flag instead of $is_outermost for avoiding duplicate output filtering, so that an outer runscript, which sets $is_outermost but does not activate the make filter, will not prevent the make filter from being activated when make is invoked
bugfix: bin/make: need to use sys_cmd instead of command so that the system make command is invoked instead of the wrapper (which would cause infinite mutual recursion for the ~/bien working copy, although not for the ~/Dropbox/svn working copy because nonrecursive=1 was able to remove the single recursion)
bin/make: use .rel to do relative includes
bugfix: bin/make: do not alter the PATH passed to the invoked make command, since this is a general-purpose wrapper and is not linked to a specific working copy (it could be used to wrap any make invocation, not just for commands in the svn dir). this uses lib/sh/local.sh's new PATH_add= flag.
bugfix: bin/make: need to leave bin/, ~/bin/ in the PATH when running make nonrecursively, so that commands invoked by it which are located in these dirs (e.g. put, which will be used by `make inputs/upload`) can still be found. this requires using command()'s new nonrecursive=1 flag instead of running no_PATH_recursion, so that no_PATH_recursion() only affects the resolution of the command path, but does not propagate the filtered PATH to the invoked command itself.
bugfix: bin/make: use verbosity_compat because some make-invoked commands (e.g. bin/map) don't support verbosity=""
bugfix: bin/make: include local.sh so that its default verbosity-setting make() override will be used
bugfix: bin/make: use standard make logging port (1) instead of $log_fd (30) so that the output of bin/make can in turn be filtered by util.sh using the standard cmd_log_fd=1
bin/make: use `readlink -f` on BASH_SOURCE0 so that this script can also be run via a symlink
bin/make: don't print make cmd by default, so that only `make` output is printed at verbosity 1
bin/make: don't reinvoke make() if the make filter has already been set up, as indicated by $is_outermost (instead, invoke make directly using exec)
added bin/make, which runs make, hiding verbose messages about making included Makefiles. this should be used in preference to plain make, to avoid excessive log messages that prevent the user from seeing the core commands that are being run.
