728a4634a1 replace var_entry_t with env_var_t 
This is a step to storing fish vars as actual vectors rather than flat
strings.

745a88f2f6 Revert "Fix clearing abandoned line with VTE (#4243)" 
Unfortunately, this breaks the expect tests.

So, until I can figure out how to unbreak them:

This reverts commit 09cb31a172.

cf00162340 Fix clearing abandoned line with VTE (#4243) 
* Fix clearing abandoned line with VTE

With VTE-based terminals, resizing currently causes multi-line prompts
to go weird.

This changes the sequence we use to clear the line to one suggested by
a VTE
developer (https://bugzilla.gnome.org/show_bug.cgi?id=763390#c4).

It changes nothing in konsole 17.04.3 and urxvt 9.22, but they already
work.

Note that this does not fix the case where output did not end in a
newline, but that doesn't seem to be up to us. Also, it only affects
those lines.

Fixes #2320.

* Use terminfo definition instead of hardcoding

Thanks to @ixjlyons.

11f5bbf83d remove completions for . and source 
These completions never actually worked and always fell back to the
builtin path completion. But a recent fix means that these now keep the
fallback from happening resulting in no completions for these commands.

4f5bd08b20 improve set -U warning 
Doing `set -U var` when a global named `var` exists can result in
confusing behavior. Try to limit the confusion by improving the warning
we write. Also, only write the warning if interactive.

8b8a21dcad Fixed exec failure regression 
The process_t pointer sent to setup_child_process can actually be 0
without it being failure, as that is what fish sends when `exec` is run
(in the case of INTERNAL_EXEC).

This was causing exec to fail.

Mahmoud Al-Qudsi
25afc9b377 Changed how process groups are assigned to child processes 
There is no more race condition between parent and child with
regards to setting the process groups. Each child sets it for themselves
and then blocks indefinitely until the parent does what it needs to for
them (having waited for them to set their process groups). They are not
SIGCONT'd until the next process in the chain (if any) starts so that
that process can join their process group and open the pipes.
