Christian Couder aaca161e1e fast-import: use early_scan_options() for --allow-unsafe-features 
The "feature" lines at the start of the stream are processed before the
command line options are parsed, so cmd_fast_import() scans its
arguments early to find out if `--allow-unsafe-features` was given.

That scan doesn't know which options take their value as a separate
argument, and it stops at the first argument that doesn't start with a
dash. So it disagrees with parse_options(), which accepts values
separated from their option by a space, for a command line like
"--depth 5 --allow-unsafe-features": the scan stops at "5" and never
sees the option, so unsafe "feature" commands from the stream are
refused even though the option was given.

Let's fix this by building the options for the scan from the same
`struct option` array that parse_options() uses, so that both agree on
which options take a value.

Note that the scan still only matches the exact option spelling, while
parse_options() also accepts unambiguous abbreviations, so the two still
disagree for a command line like "--allow-unsafe". This errs on the safe
side, and is now documented as a restriction.
