This is needed by CreateSubRequest, which creates a sub-request
using some subset of the passed IO vectors. In the case that the
last vector will not be fully used, we need to clamp its size
in the sub-request to the remaining length.
do_iterative_fd_io, used by vfs_read_pages (which is in turn
used by the file cache) used this to split up requests
into their constituent block-run requests. So, previously,
the invalid IO requests created by this could, under one possible
interpretation, overwrite valid file data and cause disk corruption.
It is slightly unfortunate that generic_size_t has no unsigned
equivalent, so we are left with 0 as the magic number here,
instead of -1. However, the passed "length" remains unchanged,
so any callers that pass the wrong value for lastVecSize
will be trapped by the assert added in the previous commit
Fixes#15912 (the assert added in the previous commit),
and potentially disk corruption caused by this.
Per POSIX.1-2008, getpeername() shall fails if the socket is not
connected.
With this change, it's no longer possible to retrieve the peer from
connectionless protocols such as UDP, even if a peer is assigned to them
via connect(). The same behavior can be replicated among
POSIX-compatible operating systems such as Linux.
Fixes#15081

By default, Haiku does not provide localised names for applications and
preference names. This commit changes the default setting to 'true',
for displaying the localised variants.
This is generally bad UX, especially for the preference preflets,
since the user will have no idea where to go if he/she does not
speak English (even will not be able to find this setting presumably).

When bounce buffers were changed from fixed to dynamic in hrev27185, the
early unlock in case of physical vectors was not removed. This would
lead to an unprotected fBounceBuffers list and the possibility for
multiple operations to share the same bounce buffer vecs, leading to
disk corruption. This would not happen when used purely under the
IOScheduler as all translations are done from a single thread there.
With the nvme_disk driver that runs requests in parallel, this was
however easy to trigger.

Passing "1" as the bytes argument instead of "0" means that
get_memory_map would never return an error in the case that
one physical_entry was not enough for the vaddr's map.
This reveals the true cause of the disk corruptions:
libnvme is assuming some of the passed buffers are
physically contiguous, and they are not.
This way, if something stalls in an unexpected way, the whole system
won't just hang.
Should "fix" #15874, but there is probably some other underlying
problem.
Reported by translator loic (thanks!). The double space is only removed in
user-facing strings, I did not touch the comments.
For those interested in an internet controversy, search the internet for
the origins of the double space after a period. In any case, for consistency with
other user facing strings, go to a single space after a period.
