Issue 5050 - bdb bulk op fails if fs page size > 8K

[progier389]

Issue: Getting replication failure when db is set on file system having page size greater than 8K
libdb - BDB0623 DB_MULTIPLE/DB_MULTIPLE_KEY buffers must be aligned, at least page size and multiples of 1KB
bdb_map_error - bdb_public_cursor_bulkop failed with db error 22 : Invalid argument

because when using bdb, db bulk operation (that retrieve several records in a single operation) must have a buffer size that is both 1024 bytes aligned and greater of equal to the db page size which default to the underlying file system page size
(and the initial buffer size is hardcoded to 8K in ds389)

Solution is to alloc a new buffer if the provided buffer does not fulfill the requirements.

Ack from me, @Nascire or @croadfeldt if you are able to test this that would be lovely!

You fine folks don't happen to have a pre-built container for this PR by chance do you? Otherwise, will try to spin one up myself.

There are rpms for F35 built from this PR: https://github.com/389ds/389-ds-base/suites/5165071779/artifacts/156447124
So you can try to add them on top of you existing freeipa container image (ADD dist/rpms /tmp, RUN dnf install -y /tmp/rpms/*, etc.)

I'll try the reproducer with proxmox later today as well.

I gave it a spin, now it's a different error message:

Thank you Victor !
FYI: I fixed the second issue. Could you test it please ?

Thank you, Pierre!
