Fixes #799

Closes #823

See merge request redox-os/ion!885

This commit adds separate quote handling to parsing
arguments inside the method body instead of checking
the global quoting state of the shell.

__dfly_error() was removed from Rust many years ago.

DragonFly uses a thread-local errno variable, but #[thread_local] is
feature-gated and not available in stable Rust as of this writing
(Rust 1.31.0). We have to use a C extension to access it.

Tracking issue for `thread_local` stabilization:

    https://github.com/rust-lang/rust/issues/29594

Once this becomes stable, we can simply use:

    extern { #[thread_local] static errno: c_int; }

Fix `time` to measure control-flow blocks

Closes #829

See merge request redox-os/ion!883

Do as bash does, and ignore multiple calls of `time`.

This commit fixes the control-flow stack building
for the `Statement::Time` variant.
`Statement::Time` is handled as a block if `parse()`
returns a block-like (partial) statement wrapped by `time`.

For convenience `is_block()` is added to make the check
less verbose.

Fixes #829

Comment in test for 'or' since it now works.
