honor the --docdir configure option.  The projdocdir variable is replaced by docdir variable. projdocdir had the same functionality as --docdirconfigure option.  The default docdir value is: $(prefix)/share/doc/$(PACKAGE) (is the same as --enable-fhs option)

Don't close file descriptors we don't own.
Fix cf-serverd stat()'ing the file tree every second.

The real problem is that signals are ignored by the event loop if they
arrive between calls to select(). The Linux approach would be to use
pselect(), but this doesn't work on some other platforms, most of all
Windows.

So instead we use a different approach: Writing to a socket is safe to
do in a signal handler according to POSIX, so we do that and listen to
that socket in the select() call.

The approach has been tested on both Linux and Windows, and is
verified to work even when forcing the signal to arrive before the
select() call is entered.

As part of this fix, the stat() timeout has been raised to one minute,
so that we still check for file changes reasonably often.

Fixes issue #3479.

Redmine#3279: add storejson() function
cf-agent --bootstrap fails on Debian systems, because sys.workdir/inputs is a symlink to /etc/cfengine3. The bootstrap creates 'failsafe.cf' in /etc/cfengine3, but cf-agent complains that this sys.workdir/inputs is a symlink. Both must fail/complain or we accept symbolic link to a
directory.

This patch enable the last option. It will determine if the destination is a symlink to a directory and ```copy_from``` attribute ```type_check : false``` is set.  If both options are true the copy will be honoured.
