346844b730 librpc: Change type of ‘u16string’ from ‘const uint16_t *’ to ‘const unsigned char *’
A u16string is supposed to contain UTF‐16 code units, but
ndr_pull_u16string() and ndr_push_u16string() fail to correctly ensure
this on big‐endian systems. Code that relies on the u16string array
containing correct values will then fail.

Fix ndr_pull_u16string() and ndr_push_u16string() to work on big‐endian
systems, ensuring that other code can use these strings without having
to worry about first encoding them to little‐endian.

59b9432524 conditional_ace.idl: Fix undefined shift
If ‘int’ is a 32‐bit type, then 1 << 31 cannot be represented in an
‘int’, and this shift will invoke undefined behaviour.

We have got away with this so far because of a Pidl bug that changed the
expression to ‘(uint32_t)1 << 31’, which is valid. But that bug is about
to be fixed.

e81e070638 librpc/idl:security: add claims flag indicating orderly and unique members
The same flag will be used in conditional ACE composites, and on
CLAIM_SECURITY_ATTRIBUTE_RELATIVE_V1 structures derived from wire
claims and resource attribute ACEs, when we know we have checked the
claim has no duplicate values.

Resource Attribute ACEs contain CLAIM_SECURITY_ATTRIBUTE_RELATIVE_V1
at rest, but we are not going to set the flag there on the off chance
that the ACE could fly off to another application and have another
application specific meaning there. We will only check for uniqueness
and set the flag on ephemeral copies of resource claims during access
check operations.

6aa6ef4b7c librpc/idl:conditional_ace: make a flags field 32 bit
This allows it to align with
CLAIM_SECURITY_ATTRIBUTE_RELATIVE_V1.flags, with which it shares
values and will soon share more.

It was 16 bit because we needed few flags, and at one point .type was
8 bit, so 16 bits packed nicely into a smaller struct.

f94b981e86 pidl: Add new ‘u16string’ type
This type represents a UTF‐16–encoded string. These strings are kept
UTF‐16–encoded rather than converted to the Unix charset to be stored in
memory; this avoids issues regarding NULL termination and conversion
between character sets. We want to be able to handle strings that are
not valid UTF‐16.

Not bumping the NDR ABI version, because there hasn’t been an NDR
release since commit c4f281e9ae.

This in turn causes trouble for round-trip testing, so it is easiest
