builtin/refs: add verify subcommand

Introduce a new subcommand "verify" in git-refs(1) to allow the user to
check the reference database consistency and also this subcommand will
be used as the entry point of checking refs for "git-fsck(1)".

Add "verbose" field into "fsck_options" to indicate whether we should
print verbose messages when checking refs and objects consistency.

Remove bit-field for "strict" field, this is because we cannot take
address of a bit-field which makes it unhandy to set member variables
when parsing the command line options.

The "git-fsck(1)" declares "fsck_options" variable with "static"
identifier which avoids complaint by the leak-checker. However, in
"git-refs verify", we need to do memory clean manually. Thus add
"fsck_options_clear" function in "fsck.c" to provide memory clean
operation.
