Change how we separate toplevel and global scopes
...
Instead of introducing a new local scope at the point of `set`, merely
push a new local scope at the end of env_init(). This means we have a
single toplevel local scope across the lifetime of the fish process,
which means that
set -l foo bar
echo $foo
behaves as expected, without modifying the global environment.

set: Don't create empty var when erasing index
...
When using `set -e foo[1]` to erase an index, if the variable doesn't
already exist, return 1 instead of creating it as an empty variable.

Add an optional mode to env_get_string()
...
The mode restricts the scope in which the variable is searched for.
Use this new restricted scope functionality in the `set` builtin. This
fixes `set -g` to not show local shadowing variable values, and also
allows for scoped erasing of slices.

set: Print an error when setting a special var in the wrong scope
...
When attempting to set a readonly or electric variable in the local or
universal scopes, print an appropriate error. Similarly, print an error
when setting an electric variable as exported. In most cases this is
simply a nicer error instead of the 'read-only' one, but for the 'umask'
variable it prevents `set -l umask 0023` from silently changing the
global value.

set: Don't treat toplevel scope the same as global
...
When using the `set` command with the -l flag, if we're at the top
level, create a temporary local scope. This makes query/assignment
behavior be consistent with the value-printing behavior.
This works by marking the current block as needing to pop the
environment if a local scope was pushed. I assume this is safe to do. I
also assume the current block is the right one to modify, rather than
trying to walk up the stack to the root.

Large set of changes to how PATH is handled. Changed fish to no longer modify PATH in share/config.fish. Introduced variable fish_user_paths, and a glue function __fish_reconstruct_path that splices together PATH with fish_user_paths. Changed fish to no longer validate changes to PATH unless the paths are new (i.e. don't recheck what's already there). Modified certain sets to store const wchar_t instead of wcstring to save a few allocations.

Add index ranges
...
Builtin 'set' now can set variable index ranges:
set test[1..3] a b c #works
set test[-1..-3] a b c #works if variable have enough elements
set test[2..-2] a b c #works
set test[1..3 -1..-2] a b c b b #works
Expand now can parse index ranges. But not handle for now.
TODO:
* Add variable substitution index ranges: echo $PATH[-1..1]
* Add command substitution index range: echo (seq 10)[-1..-4]
* Add process substitution indexes and ranges: echo %vim[-1]
