0ca81e7cec Fix: Kakoune passed environment variables in shell invocations are repeated 
If a %sh{} script refers to any variables multiple times they are all multiply
included in the environment. Example: if a %sh{} invocation refers to
${kak_buffile} 5 times, the environment will have "kak_buffile=..." repeated 5
times and so on. This repetition happens for each multiply used variable that
is passed into the environment.

The variable should, of course, be only passed into the environment once. This
commit should fix this issue.

4a59018dcd Do not select on non-urgent fd when handling only urgent events 
This avoids 100% CPU usage when we have pending fifo input while running
a shell process, as we will not end-up busy looping in pselect but not
reading the available data due to being only processing urgent events.

This should be rare but should not happen silently, this way it will

74c337df5d Add a libexec/ directory and use it to find the kak command 
Add that libexec directory to the PATH instead of the current kak
binary directory to avoid impacting other commands.

The libexec directory currently only contains a symlink back to
the Kakoune binary.

a4f830f143 Use _exit() after vfork() 
Closes #2620

The docs for Mac OS X's vfork() requires it, and _exit() conforms to
POSIX.1-2008.

b897a18aa6 Use a dummy function for SIGPIPE instead of SIG_IGN 
SIG_IGN is inherited after 'execve' and requires us to reset
that signal handler, which does not work well with vfork on
OSX. Using an empty function does the trick and will be auto
reset to default on exec.

5250593129 ShellManager: Use vfork instead of fork 
When large buffers have been opened, copying Kakoune's memory
page descriptors can get pretty slow, making fork more expensive
than necessary.

vfork avoids that problem. While not strictly conforming, it seems
the few calls we do before execve (open, close, dup2 and
set_signal_handler) would not cause any problems on platforms we
care about.
