24905ba82d docs-xml: remove explicit "constant"
The constant mark applied to types "string" and "ustring". The previous patches
in this patchset already markes all string options as either constant or
substituted, but it's still possible to add options or change existing ones to
be neither constant nor substituted.

In order to enforce strings to be either constant or substitued, remove the
explicit constant marker. Instead, any option that is not marked as substituted
is implicitly made constant.

This patch doesn't change behaviour and all generated files are the same before
and after this change.

3fea05e01f smbd: Remove write cache
Since this was written, our write path has changed significantly. In
particular we have gained very flexible support for async I/O, with the
linux io_uring in the pipeline. Caching stuff in main memory and then
doing a blocking pwrite nowadays does not belong into the core smbd
code. If someone wants it back, it should be doable in a VFS module.

Removes: "write cache size" parameter.

hiding it in the code. This change also has the code match the

f90cf49970 s4 smdb standard: Limit processes forked on accept.
Limit the number of processes started by the standard model on accept.
For those services that support fork on accept, the standard model forks
a new process for each new connection. This patch limits the number of
processes to the value specified in 'max smbd processes', a value of
zero indicates that there is no limit on the number of processes that
can be forked.

84f07a8dcb s3/smbd: fix handling of delete-on-close on directories
This implements a check to test the delete-on-close flag of a directory
for requests to create files in this directory.

Windows server implement this check, Samba doesn't as it has performance
implications.

This commit implements the check and a new option to control it. By
default the check is skipped, setting "check parent directory delete on
close = yes" enables it.

c4be0b7ff4 s3: smbd: Change aio_pending_size static variable to a new "aio max threads" smb.conf parameter.
Removes accessor functions as now this parameter is set
under user control in smb.conf. Default is 100.

Note that this doesn't limit the number of outstanding
aio requests, it just causes them to go onto the
pthreadpool queue.

Now we need to prioritize pthreadpool pipe replies
ahead of incoming SMB2 requests, but that's a patch
for another day.

Based on ideas from Volker.
