This is better than doing a strlen() on the string, as that huristic
only worked for ASCII strings.

Introduce a new flag, LIBNDR_FLAG_STR_RAW8, which indicates that libndr
should not attempt to convert the corresponding byte sequence, and place
the responsibility on the caller to do so later.
This is needed in cases where the string is known to be 8-bit and either
NULL terminated or of known length, but in an unspecified character set.
For example, when pulling PT_STRING8 properties from an exchange server
via libmapi + libndr, the codepage is neither known nor in the control
of the caller, and is determined by subsequent properties requested from
the server. Therefore the client would like to fetch all properties in
one large batch, and convert the resulting strings locally.
This commit also includes some (basic) tests of each of the flags'
respective behaviors with the ndr push/pull string functions, in a new
source4 torture test suite ndr.ndr_string.

Reduce the amount of duplicate code in ndr_pull_string by moving the
almost duplicate conversion calls and their corresponding NDR pulls and
checks to a single location. In the place of the removed calls is logic
allowing the conversion to be generalized, and and any specific
pulls/checks that do not apply to the general case.
This is similar to what has already been done in the switch statement
for ndr_push_string.

Makes these interfaces much harder to misuse and easier to ensure error
checking.

but it does :-).
Turns out one of the *really* significant differences between
convert_string() in source4 and source3, is that the one in
source3 will return 0 for byte length converted when called
with dest_len = 0 whereas the one in source4 returns (size_t)-1
and sets errno to E2BIG.
Allow the ndr_string code to cope with the (arguably correct)
way that the source4 implementation works. This code only gets
excercised in the print spooler tests, which aren't run in source4,
which is why this bug has lasted for so long.
You don't want to know how long it took me to find this :-).
Jeremy.

convert_string*()
we shouldn't accept bad multi-byte strings, it just hides problems

This fixes the calculation of needed space for destination unicode charset.

Before we ignored the charset type.
