db98ee13a9 Make complete() return the completion list directly 
Returning it through a pointer was a remnant of pre C++-11 days.

f1ce967dfa Do not allow empty items to be added to history 
Empty items are used as sentinels to indicate that we've reached the end of
history, so they should not be added as actual items. Enforce this.

cca57a7a87 fish_tests to set HOME and other variables to temporary dir 
Rather than placing files in the user's home directory, have fish_tests
manipulate HOME to be a temporary directory.

0531c02ce4 Remove 'user_supplied' flag for io_fd_t 
user_supplied was used to distinguish IO redirections which were
explicit, vs those that came about through "transmogrphication." But
transmogrification is no more. Remove the flag.

09f8e05b80 Clean up the return type of parser_t::eval 
parser_t::eval indicates whether there was a parse error. It can be
easily confused with the status of the execution. Use a real type to

33aff87c10 Switch io_file_t to store an fd, not a path 
Prior to this fix, a file redirection was turned into an io_file_t. This is
annoying because every place where we want to apply the redirection, we
might fail due to open() failing. Switch to opening the file at the point
we resolve the redirection spec. This will simplify a lot of code.

be685faeb8 Clean up how pipe fd avoidance works 
fish has to ensure that the pipes it creates do not conflict with any
explicit fds named in redirections. Switch this code to using
autoclose_fd_t to make the ownership logic more explicit, and also
introduce fd_set_t to reduce the dependence on io_chain_t.

7d5b44e828 Support FOO=bar syntax for passing variables to individual commands 
This adds initial support for statements with prefixed variable assignments.
Statments like this are supported:

a=1 b=$a echo $b        # outputs 1

Just like in other shells, the left-hand side of each assignment must
be a valid variable identifier (no quoting/escaping).  Array indexing
(PATH[1]=/bin ls $PATH) is *not* yet supported, but can be added fairly
easily.

The right hand side may be any valid string token, like a command
substitution, or a brace expansion.

Since `a=* foo` is equivalent to `begin set -lx a *; foo; end`,
the assignment, like `set`, uses nullglob behavior, e.g. below command
can safely be used to check if a directory is empty.

x=/nothing/{,.}* test (count $x) -eq 0

Generic file completion is done after the equal sign, so for example
pressing tab after something like `HOME=/` completes files in the
root directory
Subcommand completion works, so something like
`GIT_DIR=repo.git and command git ` correctly calls git completions
(but the git completion does not use the variable as of now).

The variable assignment is highlighted like an argument.

Closes #6048
