samba-tool dns zoneoptions: timestamp manipulation options

There was a bug in Samba before 4.9 that marked all records intended
to be static with a current timestamp, and all records intended to be
dynamic with a zero timestamp. This was exactly the opposite of
correct behaviour.

It follows that a domain which has been upgraded past 4.9, but on
which aging is not enabled, records intended to be static will have a
timestamp from before the upgrade date (unless their nodes have
suffered a DNS update, which due to another bug, will change the
timestmap). The following command will make these truly static:

$ samba-tool dns zoneoptions --mark-old-records-static=2018-07-23 -U...

where '2018-07-23' should be replaced by the approximate date of the
upgrade beyond 4.9.

It seems riskier making blanket conversions of static records into
dynamic records, but there are sometimes useful patterns in the names
given to machines that we can exploit. For example, if there is a
group of machines with names like 'desktop-123' that are all supposed
to using dynamic DNS, the adminstrator can go

$ samba-tool dns zoneoptions --mark-records-dynamic-regex='desktop-\d+'

and there's a --mark-records-static-regex for symmetry.

These options are deliberately long and cumbersome to type, so people
have a chance to think before they get to the end. We also introduce a
'--dry-run' (or '-n') option so they can inspect the likely results
before going ahead.

*NOTE* ageing will still not work properly after this commit, due to
other bugs that will be fixed in other commits.

fstrcpy into a possibly NULL buffer, free original string, then

Even though SMB_VFS_CONNECTPATH() returns a const char,
vfs_shadow_copy2() can free and reallocate this whilst
in use inside process_symlink_open().

Take a copy to make sure we don't reference free'd memory.
