fast-import: move command state globals into 'struct fast_import_state'

A previous commit introduced 'struct fast_import_state' to hold some
command state, and reduce the need for global variables.

Let's continue in the same direction and move two more global variables
that describe the command state into it: 'seen_data_command' and
'allow_unsafe_features'.

All the sites accessing these variables are already in functions that
receive the 'state' parameter (or in cmd_fast_import() which owns the
struct), so no additional threading is needed.

As 'state->allow_unsafe_features' is now dereferenced in
check_unsafe_feature(), its 'state' parameter is no longer unused, so
the UNUSED marker is removed.

The fast_import_state_init() call is moved up before the early
command-line scan for '--allow-unsafe-features', so that this option
can be recorded directly into the struct without being clobbered by
the memset() in fast_import_state_init().

This is a mechanical refactoring with no intended behavior change.
