* copy the ldb_options passed to ldb_connect onto the ldb_context,
making them more generally available.
* fix index buffering.
As a performance enhancement the indexes are cached in memory during a
transaction, and written to disk as part of the prepare commit. The
indexes could become corrupt in the event of a failed operation.
* fix read beyond buffer
Calling the "ldb_parse_tree" function with a filter consisting of
exactly a single space (" ") would trigger a read beyond the input
buffer.

Copy the options supplied to to ldb_connect, and place them on the
ldb_context. This allows backend options i.e. lmbd map size to be passed
cleanly from the callers.

get_FileIndex() returns a stable and unique numerical identifier when "store dos
attributes" is enabled. It is NOT the same as a file's inode number which used
as the key for locking.tdb.
For POSIX clients we should return the inode numbers in the POSIX query info
level and the FileIndex in the corresponding SMB protocol fields (eg SMB2 QFID
create context).
This fix lets test "smbtorture_s3.plain.CLEANUP3" test work with get_FileIndex()
returning something different then the file's inode number.

This doesn't cause visible damage in vanilla Samba, but would affect downstream

For the same reason there's no test.

The internal string conversion routines smb_strtoul(l) return
an error if the provided string could not be converted to an integer.
This can be the case if the string is empty or if it starts with non-numeric
characters which cannot be converted.
The standard C library, however, does allow this and simply returns 0 as the
converted value.
If this behaviour is wanted, it can be enabled by using
the "SMB_STR_ALLOW_NO_CONVERSION" flag.

The standard string to integer conversion routines stop at the first
character which cannot be converted to a number.
However, if such a character is found, it is not considered an error.
With the flag "SMB_STR_FULL_STR_CONV" enabled, an error will be returned
if the string could not be converted entirely.

The standard string to integer conversion routines allow strings
with a leading "-" to indicate a negative number.
However, the returned value is always an unsigned value representing
the bit-pattern of this negative value.
Typically, this behaviour is NOT wanted and therefore the standard
behavior of the internal smb_strtoul(l) return an erros in such situations.
It can be enabled though by using the flag SMB_STR_ALLOW_NEGATIVE.
This test verifies the correct processing.
