This goes directly into the database, for which the format changes

Previously, we did this only when writing out the locking.tdb
record. That was because we had places where the index of a particular
share mode entry mattered while operating on the array. This is no
longer the case, so we can remove stale entries early.

All places that matter explicitly check for staleness. This cleanup
action should only happen before writing the database

We have to break leases referenced from multiple share modes only
once.

The durable reconnect mainly has to check that there is one and only one
entry, and it has to reset it with the new values.

Avoid the full fsp, this makes the indexing of the share mode array
clearer, and it makes the next commit easier

Why? Next commit will make share_mode_forall_leases() use
share_mode_forall_entries(), and that does not necessarily have to
depend on "share_mode_lock". And as we can pass the required
information via "private_data", don't embed the "share_mode_lock"
reference into this lowlevel library routine.

Abstract away the fact that we store the share modes as an array inside
"struct share_mode_data".

Make the real data dependencies clearer, we don't need a full
share_entry, only its access and sharemode masks

It was hard for me to understand share_conflict(), so once I understood
it I thought this version would be easier to follow. It violates
README.Coding (one argument per line), but grouping the parameters to
mask_conflict makes it clearer to me what belongs together.

Mind the missing space before "(e.g. another...". While there, avoid

Less bytes .text, the compiler now does not have to expect other threads to

The same lease can be used via different TCP connections (yes, we have
tests for this!). At the end of downgrade_lease() we update all fsp's
with fsps_lease_update() that link to the lease that just was
changed. However, this is only in the local process, this is not
cross-smbd. So other smbds using the same lease can use stale
information and for example get the mandatory locking wrong.

Believe it or not, but without this change "num_files" was first.
Thanks Metze for this (to me at least) really, really surprising
