The default debug level of smbclient is set to 'log level = 1'. So we
need to use at least NOTICE to not get the message when we do not force

This should be significantly faster than pwriting.
openbsd doesn't have posix_fallocate, so we do need the fallback. Also, it
might have weird failure modes, so we keep the old code in place except for
posix_fallocate returning success or ENOSPC.

Without this it's very easy to create virtually huge files: ftruncate expands a
file, the pwrites fail with ENOSPC, thus the write fails. The next writer runs
into the same situation, and ftruncate-expands the file even further. tdb_check
will then spend ages reading the 4GB of zeros byte by byte.
Here we hold the freelist lock or are inside a transaction, so it is safe to
cut the file again. Nobody can have used the space that we have tried to
allocate, so we can't have any stray pointers corrupting the database.

This checks for posix_fallocate unless we are sitting on an ancient glibc.
With this we don't need HAVE_BROKEN_POSIX_FALLOCATE anymore,
HAVE_POSIX_FALLOCATE will only be defined if we have a valid [g]libc.
./configure tested on Debian, FreeBSD (which does have posix_fallocate) and
OpenBSD (which does not have posix_fallocate). Also tested with changing the
not have an old-enough glibc around. All did the right thing.

Current code assigns errno from async pthreadpool calls to the
vfs_default internal vfswrap_*_state. The callers of the vfs_*_recv
functions expect the value from errno in vfs_aio_state.error.
Correctly assign errno to vfs_aio_state.error and remove the unused
internal err variable.

This makes vfs_acl_common.c a subsystem of its own that acl_xattr and acl_tdb
now link against, not #include it.
This patch is a bit on the large and clumsy side, but splitting it up would
(I believe) involve a separate intermediate copy of acl_common.c.

Due to the non-fixable bug in the BUCKET macro tdbtool list printed some
other hash chainlist, not the freelist.

The following C program demonstrates the issue:
#include <stdio.h>
#include <stdlib.h>
#include <stdarg.h>
#include <stdbool.h>
#include <string.h>
#include <unistd.h>
#include <errno.h>
#include <dirent.h>
#include <sys/types.h>
int main(int argc, char **argv)
{
int hash = -1;
int tsize_signed = 10;
unsigned int tsize_unsigned = 10;
int bucket;
#define BUCKET(hash, tsize) ((hash) % (tsize))
bucket = BUCKET(hash, tsize_unsigned);
printf("hash [%d] tsize [%d] bucket [%d]\n", hash, tsize_unsigned, bucket);
bucket = BUCKET(hash, tsize_signed);
printf("hash [%d] tsize [%d] bucket [%d]\n", hash, tsize_signed, bucket);
return 0;
}
Output:
$ ./tmp
hash [-1] tsize [10] bucket [5]
hash [-1] tsize [10] bucket [-1]
The first version is what the current BUCKET() macro does. As a result
we lock the hashtable chain in bucket 5, NOT the freelist.
-1 is sign converted to an unsigned int 4294967295 and
4294967295 % 10 = 5.
As all callers will lock the same wrong list consistently locking is
still consistent.
Stumpled across this when looking at the output of `tdbtool DB list`
which always printed some other hashchain and not the freelist.
The freelist bucket offset computation doesn't use the BUCKET macro in
freelist.c (directly or indirectly) when working on the freelist, it
just directly uses the FREELIST_TOP define, so this problem only affects
tdbtool list.
